RING GUIDE

 

Series Number: IB  Internal Basic  Ring

The IB series rings are designed to compress for installation into the groove of a bore or housing.  The portion of the ring extending above the groove holds the assembly in place.  By design, constant rotation speeds are of no consequences to the IB series, since centrifugal forces cause the rings to seat tighter against the groove.  Lugs are internal to the ring.

Size Range: .250 – 10.0 inches (6.4mm -  254.0mm)

Series Number: XB  External Basic Ring

The XB series rings are designed to expand when installed over a shaft for installation into a groove.  The portion of the ring extending above the groove holds the assembly in place.  The XB series are often used in assemblies subjected to strong centrifugal forces and high rotation speeds.  Lugs are external to the ring.

Size Range: .125-10.0 inches (3.2mm – 254.0mm)

 

Series Number: IIV Internal Inverted Ring

The IIV series rings differ from the IB Series in two ways.  Although used in a compression mode for insertion into a bore or housing, the section height has been increased and the lugs are inverted so they fit the bottom of the groove.  The lug design, inverted rings provide less contact surface with the groove wall and therefore have somewhat lower thrust load capacity than either the IB or the XB series basic rings.  The IIV series reduces the distance the lugs of the standard IB series ring extends beyond the circumference of the housing, thus allowing another assembly to pass through its’ center unrestricted.  The lug design and increased section height provides a higher shoulder than the basic ring, one that is uniformly concentric to the housing.  For this reason inverted rings are ideal for locating and retaining lenses, seals and other components having curved surfaces.  The higher shoulder also makes it possible for the rings to accommodate ball and roller bearings and other parts with large corner radii or chamfers.  Also, the uniform shoulder provides a more pleasing appearance than the basic style rings.  This feature lends the inverted style to be better suited to external applications such as on cameras, office machinery, home appliances and other applications where products must be ergonomically pleasing to the eye.

Size Range:  .625 – 4.0 inches (15.9mm – 101.6mm)

 

Series Number: XIV External Inverted Ring

The XIV series rings differ from the XB series in two ways.  Although used for insertion over a shaft, the section height has been increased and the lugs inverted so that they fit the bottom of the groove.  Because the lug design, inverted rings provide less contact surface with the groove wall and therefore have somewhat lower thrust load capacity than either the IB or XB series basic rings.  The XIV series reduce the distance the lugs of the standard XB series ring extend beyond the circumference of the shaft, thus ideal for the assembly of shielded bearings and other applications where clearance dimensions are critical.  The lug design and increased section height provide a higher shoulder than the basic ring, one that is uniformly concentric to the shaft.  For this reason inverted rings are ideal for locating and retaining lenses, seals and other components have a curved surface.  Also, the uniform shoulder provides a more pleasing appearance than the basic style ring.  This feature lends the inverted style to be better suited to external applications such as on camera, office machinery, home appliances and other applications were products must be ergonomically pleasing to the eye.

Size Range: .500 – 3.938 inches (12.7mm – 100.0mm)

 

Series Number: XHD External Heavy Duty Ring

The XHD series rings are an extra thick version of the basic XB series and have an increased section height.  Rings have wider lugs, which extend further into the ring, providing more uniform load distribution against the retained part.  The XHD series has high thrust-load and impact resistance and provides a shoulder with sufficient height to accommodate large corner radii or chafers.

Size Range: .394 – 2.00 inches (10.0mm - 50.8mm)

 

Series Number: IBB Internal Basic Bowed Ring

The IB01 series rings are similar in construction and application to our IB series internal flat rings, except they are bowed.  The IB01 series are designed to take up end play and to dampen vibrations and oscillations.  This bowed construction helps compensate for accumulated tolerances in groove location and dimensions of the retained parts, as well as for wear in the assembly.  Once snapped into place, bowed rings exert a force of “preload” on the assembly or part being retained.

Size Range: .250 – 1.750 inches (6.4mm – 44.4mm)

 

Series Number: XBB External Basic Bowed Ring

The XB01 series rings are similar in construction and application to our XB series external flat ring, except they are bowed.  The XB01 series is designed to take up end play and to dampen vibrations and oscillations.  This bowed construction helps compensate for accumulated tolerances in groove locations and dimensions of the retained parts, as well as for wear in the assembly.  Once snapped into place, bowed rings exert a force or a “preload” on the assembly or part being retained.

Size Range: .188 – 1.750 inches (4.8mm – 44.4mm)

 

Series Number: IBV Internal Basic Beveled Ring

The IB02 series rings are similar in construction and application to our IB series internal flat rings, except that the groove engaging end of the ring has a 15Ί beveled angle.  Beveled rings are designed to provide rigid end play take up in assemblies where manufacturing tolerances or wear in the parts cause end play between the ring and the retained part.  Once installed into a groove the beveled ring acts as a wedge between the outer groove wall and the part being retained.  It also exerts an axial force against the retained part.

Size Range: 1.000 – 10.00 inches (25.4mm – 254.0mm)

 

Series Number: XBV External Basic Beveled Ring

The XB02 series rings are similar in construction and application to our XB series external flat rings, except that the groove engaging end of the ring has a 15Ί beveled angle.  Beveled rings are designed to provide rigid end play take up in assemblies where manufacturing tolerances or wear in the parts cause end play between the ring and the retained part.  Once installed into a groove the beveled ring acts as a wedge between the outer groove wall and the part being retained.  It also exerts an axial force against the retained part.

Size Range: 1.000 – 10.00 inches (25.4mm – 254.0mm)

 

Series Number: XEB  External “E” Bowed Ring

The XEB series rings are similar in construction and application to our XE series external flat “E” ring, except that they are bowed cylindrically.  The XEB series is designed to provide end play take up in an axial direction, while maintaining a tight grip against the bottom of the groove.  Once snapped into place, a bowed ring exerts a force or a “preload” on the assembly or part being retained.  This style ring is not recommended for use as a shoulder against rotating parts, since rotation may cause the ring to become dislodged from the groove.

Size Range: .110 - .875 inches (2.8mm – 22.2mm)

 

Series Number: XC External Crescent Ring

The XC series rings are designed t be installed radially on a shaft directly in the plane of the groove.  When installed on a shaft the ring undergoes circular deformation and, consequently, maintains a tight fit against the bottom of the groove.  Because the taper is on the inner surface of the ring facing the groove, the ring provides a uniform shoulder concentric to the shaft.  This style ring is ideal for applications where clearance dimensions are critical.

Size Range: .125 – 2.000 inches (3.2mm – 50.8mm)

 

Series Number: XE  External “E” Ring

The XE series rings are by far the most popular and commonly used radial retaining rings.  The XE series is designed to provide a large shoulder on small diameter shafts for effective retention of assemblies.  Three prongs make contact with the bottom of the groove, which is usually relatively deep to increase the ring’s thrust load capacity.

Size Range:  .040 – 1.375 inches (1.0mm – 34.9mm)

 

Series Number: XER  External “E” Reinforced Ring

The XER series rings are specifically designed for assemblies where the conventional XE series rings do not provide enough retention strength as required by the application.  The XER series is particularly suited for applications requiring higher thrust loads resulting from heavy vibration and shock loads, high rotational speeds or relative rotation between the retained parts.  These rings utilize the same groove sizes as the standard XE “E” rings, giving the designer the ability to use either type without redesigning the assembly.

Size Range: .094 - .562 inches (2.4mm – 14.3mm)

 

Series Number: XK & XKT External Klip Ring & External Klip Thin Ring

The XK & XKT series rings are unique styles of heavy-duty radially assembled rings, which provide substantially greater gripping strength and load capacity than convention “E” rings or similar type fasteners.  The XK series is thicker than most rings and have a larger sectional height.  It is installed in a deep groove and due to its mechanical design give the XK series higher thrust load and impact capacity, as well as resistance to axial and radial push-out forces.  The ideal applications for this ring are for farm machinery, off-road equipment and similar heavy duty applications.  The XKT series is a thinner version of the XK series and fits the same groove widths as the XE series rings.  An important advantage for assemblies that require a stronger ring but the assembly design does not allow for a thicker ring.

Size Range: XK   = .156 – 2.000 (4.0mm – 50.8mm)

                     XKT = .156 – 1.000 (4.0mm –  25.4mm)

 

Series Number: XP & XPR  External Circular Push-on Ring & External Circular Push-on Reinforced Ring

The XP & XPR series rings are self locking designs and can be installed by hand onto a shaft.  The XPR series may require an assembly tool.  As the ring is forced over a shaft the prongs spread from their initial position.  The load applied from the opposite direction forces the prongs to grip the shaft.  The XP series differs from the XPR series (reinforced) in that it has a flat rim, shorter locking prongs and a smaller outside diameter.  It is recommended for assemblies where a flat contact surface with the retained part is required or where clearance dimensions are critical.  The XPR (reinforced) series differs from the XP series in three ways. First, it has a higher thrust load capacity and the reinforced arched rim provides exceptionally high strength and resistance to bending, twisting, and buckling. Secondly, it can accommodate greater shaft tolerances because of its extra long locking prongs.  Thirdly, it has wider application use and not only can it be used on precision machined shafts, but also on tubes, cast parts, plastic shafts, and studs.  As well as other parts having dimensional differences which often prohibit the use of other push-on fasteners.

Size Range:  .094 – 1.0 inches (2.39mm – 25.4mm)

 

Series Number: IP  Internal circular Push-on Ring

The IP series rings are internal self-locking styles designed for use in housings or bores.  They can be installed easily by hand or with a simple tool.  The IP series differ from the XP series in that the locking prongs are on the outside of the rim.  This series does not require an internal groove or undercut in the housing, which is a cost reduction benefit to the designer, but rings cannot be reused after disassembly.

Size Range:  .312 – 2.0 inches (7.9mm – 50.8mm)

 

Series Number: XRG  External Radial Grip Ring

The XRG series ring is self-locking and makes its own grove on a soft shaft, which significantly increases its holding power.  By design, they automatically compensate for tolerances and can be radially installed directly against the face of the retained parts, virtually eliminating end play.

Size Range:  .092 – .379 inches (2.3mm – 9.6mm)

 

Series Number: XG   External Grip Ring

The XG series ring is designed for use on ungrooved shafts, bosses, tubes, and studs.  They exert a frictional hold against axial displacement from either direction.  The XG series ring differs from the standard XB series in that it is thicker, has a larger section height and a larger outside diameter, thus providing a higher retaining shoulder.  The advantages of this series over other self-locking fasteners are greater gripping strength, resistance to relative rotation between the ring and the retained parts, wider application acceptance, adjustable in either axial direction, or reusable while not marring the shaft surface during assembly or disassembly.

Size Range:  .058 – .755 inches (1.5mm – 19.0mm)
