Product Description

Metric Basic Retaining Rings Shaft is an open-ended ring-shaped fastener made of elastic materials such as spring steel or stainless steel. It forms a protruding "shoulder" by embedding into the grooves on the shaft, and is used to axially position and fix the components (such as bearings, gears) installed on the shaft. During installation, a special ring expander is used to expand the retaining ring, allowing it to fit and "lock" into the pre-drilled grooves on the shaft.

Structural Characteristics

The structure design of the Metric Basic Retaining Rings Shaft is ingenious. It achieves convenient installation through the opening and the design of the installation hole. Moreover, by adopting various cross-sections and ear shapes, it can adapt to different force conditions and space requirements.

1.Installation mechanism

Opening and slotting

It allows for easy installation using standard locking pliers, making the operation convenient.

2.Fixed principle

Interference fit (inner diameter < shaft diameter)

Relying on elastic deformation, it fits into the shaft groove, forming a stable axial "shoulder" section

3.Section design

Conical/Variable Cross-Section (Stamping)

It can achieve uniform stress distribution, which is the solution commonly adopted by standard type Metric Basic Retaining Rings Shaft.

Constant-section (winding/friction cutting)

Uniform force distribution, capable of handling heavy-load conditions, without burrs

Spiral (multi-layer winding)

Earless design, 360° seamless contact, suitable for high-speed or shallow groove applications

4.Installation features

Ear piece (Lug)

Provides the position for the screw holes, for installation and disassembly

There are ear shapes (standard and conventional)

Including single ear designs (B or C type) and double ear designs

Earless type (screw, uniform cross-section)

No protruding ear interference, saving space
