|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
 | Basic Internal Retaining Ring/Basic Internal Snap RingOnce installed inside the groove of a housing or bore, the portion of the retaining ring protruding from the groove holds an assembly in place. Size Range: .250 - 10.0 inches (6.4 - 254 mm) |
| ||||||||||||
 | Basic External Retaining Ring/Basic External Snap RingProvides a large shoulder on a shaft by snapping into grooves on the shaft side. Once installed in the grooves, the portion of the snap ring protruding out holds an assembly in place. External placement ensures extra thrust capacity. Size Range: .125 - 10.0 inches (3.2 - 254 mm) |
| ||||||||||||
 | Inverted Internal Retaining Ring/Inverted Internal Snap RingInverted lugs seat into the groove of this retaining ring for better clearance and a cleaner appearance. Good for shielded bearings that pass tightly through the bore or housing. Size Range: .625 - 4.0 inches (15.9 - 101.6 mm) |
| ||||||||||||
 | Inverted External Retaining Ring/Inverted External Snap RingUsed 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 of the lug design, inverted retaining rings provide less contact surface with the groove wall. Size Range: .5 - 3.938 inches (12.7 - 100 mm) |
| ||||||||||||
 | Heavy Duty External Retaining Ring/Heavy Duty External Snap RingExtra-thick version of basic external retaining ring that is stronger and yields higher thrust loads. Heavy Duty External Ring has wider lugs and provide more uniform load against thr retained part. This series ring has high thrust-load and impact resistance and provides a shoulder with sufficient height to accommodate large coner radi or chamfers. Size Range: .394 - 2 inches (10 - 50.8 mm) |
| ||||||||||||
 | Basic Bowed Internal Retaining Ring/Basic Bowed Internal Snap RingCurved design for resilient end-play take-up of rattling in linkages. Provides tension on adjusting screws. Also used to salvage assemblies where grooves have been cut too wide. Install this retaining ring with the convex surface abutting the part. Size Range: .25 - 1.75 inches (6.4 - 44.4 mm) |

 | Basic Beveled Internal Retaining Ring/Basic Beveled Internal Snap RingA 15° bevel on the outside diameter, when fitted into a 15° bevel on the load-bearing groove wall, yields rigid end-play take-up of manufacturing tolerances or wear on the retained part. This retaining ring is used in greasy and oily environments. Compressed into a bore or housing. Size Range: 1 - 10 inches (25.4 - 254 mm) |
| ||||||||||||
 | Basic Beveled External Retaining Ring/Basic Beveled External Snap RingA 15° bevel on the inside diameter, when fitted to a 15° bevel on the load-bearing groove wall, yields rigid end-play take-up of manufacturing tolerances or wear on the retained part. Used in greasy and oily environments. Retaining ring expands to pass over a shaft and snap into the groove. Size Range: 1 - 10 inches (25.4 - 254 mm) |
| ||||||||||||
 | “E” Bowed External Retaining Ring/”E” Bowed External Snap RingLike all E-Style retaining rings, these fit directly into the shaft groove from the side. These rings bow to provide spring-like retention, so you can take up any end play and tighten loose assemblies. Ideal for replacing machined shoulders, washer and cotter pin assemblies, and screw and nut assemblies. Size Range: .11 - .875 inches (2.8 - 22.2 mm) |
| ||||||||||||
 | Crescent External Retaining Ring/Crescent External Snap RingIdeal for low-clearance applications where radial installation is preferred. Crescent retaining rings snap easily into place and form a narrow and uniform concentric shoulder. Size Range: .125 - 2 inches (3.2 - 50.8 mm) |
| ||||||||||||
 | “E” External Retaining Ring/”E” External Snap RingSlide these retaining rings directly into the groove from the side of the shaft. The three prongs come in contact with the bottom of the groove and provide a shoulder to retain assemblies. Size Range: .04 - 1.375 inches (1 - 34.9 mm) |
| ||||||||||||
 | “E” External Reinforced Retaining Ring/”E” External Reinforced Snap RingStamped clips for deep grooves with three prongs that yield high thrust load capacity. RE retaining rings are heavier duty for higher thrust loads and 50% higher RPM's. Size Range: .094 - .562 inches (2.4 - 14.3 mm) |
| ||||||||||||
 | PO – Klipring External Retaining Ring/Klipring External Snap RingHigh-strength retaining rings are ideal for large bearing surfaces. Unique, wide design offers extra retention surface against the retained part. Install quickly with pliers or a mallet and remove with an ordinary screwdriver when using this retaining ring. Size Range: .156 - 2 inches (4 - 50.8 mm) |

 | Radial External Grip Retaining Ring/Radial External Grip Snap RingGrip rings are stamped grooveless retainers that are radially applied using an applicator. Because there is no groove, the part may be adjusted on the shaft to take up end-play. Size Range: .092 - .379 inches (2.3 - 9.6 mm) |
| ||||||||||||
 | External Grip Retaining Ring/External Grip Snap RingThis retaining ring is designed for use on ungrooved shafts, bosses, tubes and studs. This ring exerts a frictional hold against axial displacement from either direction. 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, and reusable while not marring the shaft surface during assembly or disassembly. Size Range: .058 - .755 inches (1.5 - 19 mm) |
