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 a circlip and a snap ring?

The name snap ring generally refers to circlips which have the ends formed to aid installation and removal, and which are not formed from wire (i.e. do not have a round cross-section). These rings are designed to be installed and removed with special pliers.

How much force can a snap ring hold?

For example, a 1-3/8 external snap ring has a ring thrust load capacity of 8,222 lbs and a groove capacity of 4,100 lbs. However, these capacities are only accurate when: The housing and shaft are made from cold-rolled steel. The edge margin is within the recommended range – in this case, over 0.126 inches.

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.

Which way does a snap ring go?

Up is you want the shortest end towards you. You don't want it the other way if you look at this.

What is the purpose of a snap ring?

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.

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).

How do you size a snap ring?

First measure the furthest two points from left to right with a gap facing away from you to

How do you remove a snap ring without holes?

How Do You Remove Circlips Without Holes? If you need to remove a circlip that doesn't have holes on the ends, it is recommended to use a pair of narrow tip pliers. The fine tips of the pliers should be able to securely hold the snap ring and enable careful removal.

How do you install circlips without pliers?

Screwdrivers are sometimes also used to install circlips. The clip can be lined up and the screwdriver used to force it into the groove of a bore, or a groove on a shaft.

What's the difference between an internal and external snap ring?

Internal rings are located in a housing groove, while external rings sit in a shaft groove. All of our rings are specified as either internal or external, with the exception of an OD/ID lock ring, which functions in both. Once the assembly type is decided, the assembly size should be specified.

How do you install a retaining ring?

Spirolox retaining rings are designed to be installed by hand, so no special tooling is required. This is done by separating the turns, inserting one end of the ring over the shaft (or through the bore), and into the groove, then spiraling the rest of the ring into the groove.

What is thrust load capacity for a retaining ring?

A self-locking retaining ring, which does not need a groove, provides 66 lbs. of static thrust load capacity; an external retaining ring for the same application installed in a soft groove provides 1,200 lbs. of static load capacity with a safety factor of 2.

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.

How do you size a retaining ring?

Clip diameter — Ring size is determined by measuring the clip's free diameter, or the diameter of the clip prior to installation. Internal retaining rings are measured by their outer diameter, while external rings are measured by their inner diameter.

What is a retaining ring groove?

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. As the name suggests, an internal ring sits in a housing groove, whereas an external ring sits in a shaft groove.

How do you measure an internal circlip?

The best way to find the internal circlip size you need, is to measure the inside diameter of the bore (not the circlip groove). For example, a 30mm bore will require a 30mm circlip (keeping in mind that the 30mm circlip will not measure 30mm on the outside diameter as it is not yet compressed).

When should you use a retaining ring?

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.

Why is it important to fit the snap ring snugly during installation?

As with any metal component, if the ring is stretched beyond the yield point of the material, it will plastically deform. Deformation occurs when the installation stress exceeds the minimum tensile strength of the material.
