151 external and internal retaining rings in a pre-packaged assortment covering both shaft-mount and bore-mount snap ring sizes used in automotive and mechanical assembly. External and internal retaining rings are the standard solution for retaining bearings, gears, and bushings in assemblies where a separate nut or fastener won't fit — keeping a mixed assortment on hand eliminates per-job sourcing for routine shaft and bore work.
What's Included
- External retaining rings (snap rings) — fit into a circumferential groove on the outside of a shaft to retain components axially
- Internal retaining rings (snap rings) — fit into a groove inside a bore or housing to retain a shaft or bearing from the inside
- Multiple sizes covering common shaft and bore diameters in automotive and mechanical applications
- 151 pieces total
Specifications
| Fastener types | External retaining rings, internal retaining rings |
| Material | Carbon spring steel |
| Application | Shaft and bore retention — automotive, drivetrain, and general mechanical assemblies |
| Installation | Requires snap ring pliers (external or internal, depending on ring type) |
| Total pieces | 151 |
| Supplier | Auveco |
Best For
- Drivetrain and transmission shops — retaining rings secure bearings, thrust washers, and gear sets inside transmissions, differentials, and axle assemblies; having a stocked assortment reduces disassembly wait time
- General automotive service shops — retaining rings appear in wheel hubs, CV axle assemblies, and suspension components; a mixed assortment covers the sizes most commonly encountered
- Industrial and equipment maintenance — motors, gearboxes, and hydraulic components use retaining rings throughout; keeping common sizes on hand is basic maintenance prep
External vs. Internal Retaining Rings
External retaining rings (also called external snap rings or circlips) sit in a groove machined around the outside circumference of a shaft. They prevent a bearing, gear, or other component from sliding off the end of the shaft. Installed with external snap ring pliers that compress the ring to fit it into the groove.
Internal retaining rings sit in a groove machined into the inside wall of a bore or housing. They retain a shaft or bearing inside the housing from the inside out. Installed with internal snap ring pliers that expand the ring to fit it into the groove.
The critical dimension for both types is the groove diameter — not the shaft or bore diameter alone. Always measure the groove and verify the ring's unloaded diameter matches before installation. Never reuse a retaining ring that has been removed — the spring tension is compromised after expansion or compression. Questions? Contact us.
