What are the two types of snap rings?

There are two main types: internal and external snap ring pliers. Snap rings with internal rings and rings with external rings have some defining differences.

What are the two types of retaining rings?

Internal retaining rings are designed for retaining parts inside a bore or housing. They may feature lobes at the ring opening that protrude into the inner diameter of the ring. External retaining rings are intended for placement on the outside of the shaft, often in a machined groove.

What is the difference between a snap ring and a retaining ring?

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 the difference between internal and external snap rings?

Internal retaining rings fit into a housing or bore. External retaining rings fit over a shaft or pin.

How do I choose a snap ring?

Can I use e clip instead of snap ring?

We use e clips over snap rings because for snap rings you need to turn down the shaft to a circle. E clips don’t require the circular shaft and can easily be pressed into the machined groove (no tool is needed).

What is a retaining ring used for?

Retaining rings are used to hold components onto a shaft or into a bore. The smooth, round finish of most shafts or bores makes them difficult to attach to with alternative methods, whereas retaining rings clamp around them and create a shoulder that keeps parts in place.

What is the meaning of retainer ring?

A retaining ring is a type of industrial fastener that holds mating components or assemblies together. A retaining ring is a circular component made out of metal that sits in a groove (housing or shaft). You can have an internal (housing) retaining ring or an external (shaft) retaining ring.

What is an external retaining ring?

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 circlip and a snap ring?

What does a retaining ring look like?

How do I remove a retaining ring?

To remove this ring, simply pry out the end using a small screwdriver or staple remover, and then spiral the ring out by hand. For larger size rings, Smalley also makes a removal tool, part number RT-108, that can be used to remove the rings. The end of the tool contains a slot to insert the tip of the removal notch.

Where do retaining rings go?

Retaining rings are designed to fit into a machined groove either on the inside of a bore or on the outside of a shaft. These components reduce vibration, retain two parts of an assembly, and can withstand axial loading.

How do you size a snap ring?

How do you remove a snap ring without holes?

If you want to remove a snap ring that doesn’t have a hole, consider using a pair of narrow-tip pliers. You should be able to remove the ring without incurring injuries. Another means of removing a snap ring without holes is using screwdrivers.

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.

Where are snap rings used?

Snap rings are a great way to rapidly mount your bearings and have them adequately located axially in your application. They are often used in external applications to secure parts on grooved shafts, pins, or studs. External circlips are designed to ensure a tight fit into a grove around the outside of a shaft or rod.

How thick is a snap ring?

Constant Section (Snap) Ring

Often thought of as the strongest of the ring types, they have a thicker cross-section and square edges. Constant Section (Snap) Rings are stocked from . 375 in. to 10 in. diameters, 13 mm to 300 mm.
