DOUBLE GROOVED PIN

A DOUBLE GROOVED PIN is a precision cylindrical pin with two grooves machined into the shaft body. The two grooves can be used separately with retaining rings, circlips, seals, or other retaining components to limit axial movement, control assembly spacing, and improve positioning stability within the mechanism.

Two Grooves Provide Dual Positioning

The two grooves can be fitted separately with retaining rings or circlips to control both sides of bearings, gears, bushings, and other components, creating a clearly defined assembly position.

Precise Control of Component Spacing

By controlling the groove spacing and groove positions, the axial distance between components can be maintained more precisely, helping reduce component displacement and changes in assembly clearance.

Improves Retention Stability

The dual retaining structure helps reduce the possibility of axial movement during operation, vibration, or loading, improving overall assembly stability.

Supports Multiple Functional Configurations

The two grooves can be assigned different functions, such as positioning, sealing, oil guidance, or accommodating different retaining components, providing greater flexibility in mechanical design.

Suitable for Various Transmission Assemblies

DOUBLE GROOVED PINS are commonly used in motors, gearboxes, rollers, pulleys, automation equipment, electronic equipment, and automotive and motorcycle components.
