Circlip Round Wire Snap Rings

The following is an introduction to the working principle of the Circlip Round Wire Snap Rings.

1.Structural Foundation

The Circlip Round Wire Snap Rings is formed by winding a round-section spring steel wire into a circular ring with an opening.

In the free state, its outer diameter is slightly larger than the diameter of the target installation hole. Because the cross-section is circular, the entire ring has no sharp edges, and thus will not scratch the hole wall or mating parts during installation or use.

2.Installation process

Compress

Use the socket jaw pliers to grip both ends of the opening, and apply force to squeeze the pliers. At this point, the Circlip Round Wire Snap Rings is radially compressed, its outer diameter becomes smaller, and it transforms into a circular ring that is smaller than the installation hole diameter.

Insert into the hole

In the compressed state, insert the retaining ring as a whole into the hole and push it to the pre-machined circular groove position.

Release

Release the locking clamp. The retaining ring loses the external force constraint and, relying on its stored elastic potential energy, expands outward.

Since the outer diameter in the free state is larger than the hole diameter, the retaining ring will tightly fit into the bottom of the groove and cannot be pulled out from the hole.

Completion of positioning

After the retaining ring is inserted into the groove, a smooth annular step surface is formed inside the hole. The part to be positioned should be closely attached to this step, thereby being restricted to a certain axial position within the hole and unable to slide outwards.

3.Core working principle breakdown

Free state: Outer diameter > Hole diameter, cannot be directly inserted into the hole

Compressed state: Outer diameter < Hole diameter (utilizing elastic deformation), the locking spring applies force, the diameter decreases

Insert into slot: Maintain the compressed state, and send to the groove position

After release, working state: Outer diameter recovers > Hole diameter (limited by the groove wall), the elastic restoring force converts into radial pressure, causing the Circlip Round Wire Snap Rings to closely adhere to the bottom of the groove
