How deep should a snap ring groove be?
Groove depth (h) should be 1/3 to 1/2 of the ring’s radial width (b). This provides optimum ring stability in applica- tions with high shear forces.
What is snap ring groove?
External retaining rings (also known as “external snap rings”) sit in the grooves on the exterior of shafts of any size. The areas of the ring that protrude out from the shaft hold it in place.
What is the difference between a snap ring and a retaining ring?
There really isn’t a difference. Snap-ring and retaining ring such as # 410-21 are two names for the same thing. If your tail light looks like # ST40RB then use # A40SRB.
What is the tolerance for a retaining ring?
The ring section radial width tolerance should be ± . 004 in. (0.102 mm) minimum.
What are the different types of snap rings?
Types of snap rings
- Tapered section snap ring.
- Constant section snap ring.
- Spiral lock snap ring – you can have single-turn or multi-turn spiral rings.
- Circlip with grip holes.
- Circlip without grip holes.
How do snap rings work?
A snap ring or retaining ring has a C-shape or circular shape with a gap. The gap allows the ring to expand or compress. When installing a snap ring inside a bore or housing, you pull the ends of the ring together to compress it then release it into the groove.
What is the difference between an internal and external snap ring?
Internal retaining rings fit into a housing or bore. External retaining rings fit over a shaft or pin. They often have prongs that grip shaft or housing bore. These rings are also called self-locking.
What do snap rings do?
Retaining rings — also known as snap rings or circlips — are metal fasteners installed into a groove on a shaft, or in a housing or bore to retain an assembly. The devices keep parts in place using a compact, lightweight design that requires fewer machining operations than other fastening techniques.
What is a 1060-1075 snap ring?

What is the size of a snap ring?
Internal Retaining Snap Ring sizes and Bore Design Sizes .250 -1.500 Internal Retaining Snap Ring sizes and Bore Design Sizes 1.562 – 3.000 Internal Retaining Snap Ring sizes and Bore Design 3.062 – 5.000
What is a retaining snap ring?
Retaining snap ring is a fastener that holds components or assemblies onto a shaft or in a housing/bore when installed in a groove. Once installed, the exposed portion acts as a shoulder which retains the specific component or assembly. Circlips are a type of retaining ring.
What are the dimensions of the ring grooves?
All dimensions are in inches. Depth of groove d = (OD-ID)/2. Thickness indicated is for unplated rings; for most plated rings, the maximum ring thickness will not exceed the minimum groove width (S) minus 0.0002 inch.
