Shaft Locking Pins

Metrol Motion Control stocks high-quality shaft locking pins, also known as shaft lock pins or retaining D clips. These essential components are designed to secure shafts' ends and prevent installed clips from falling off due to excessive vibrations. Typical applications for shaft locking pins relate to vehicles and industrial engines, machine manufacturing, and marine and defence.

A shaft pin is opened when the wired section is pulled from the attached shaft, and it can be resecured by re-inserting it into the pre-drilled hole in the shaft. Our motion control experts have created various specifications for these vital components, including:

  • Different pin and loop diameters
  • Unique pin heights and widths
  • Teardrop shape.
  • You can download our complete spring and wire form catalogue to learn more about the range of specifications we supply

They can be constructed as either teardrop shape (LSR) for round shafts and tubes or square-shaped (LSS) to suit square shafts and tubes. All our manufactured shaft pins are compliant with DIN 11023.
