Reduce your fastener assembly costs by designing in a Rotor Clip Retaining Ring. Consider replacing costly traditional fasteners with retaining rings and enjoy savings you didn't  know were possible. ROTORCLIPS® can also handle many "Non-Traditional" fastener requirements for even greater savings.

Before you designate a ROTORCLIP® for your application, follow these simple steps:
determine the retaining ring type
If the assembly you must retain is in a housing/bore, then you need an internal type or HOUSING (HO) ring.


If the assembly you must retain is on a shaft, then you need an external type or SHAFT (SH) ring.


If you are looking for a retaining ring to act as a spring or as a preload on parts to reduce chatter or vibration, then you need either a bowed (BHO, BSH for resilient end-play takeup) or a beveled (VHO, VSH for rigid end-play takeup) retaining ring. These are available for both internal and external applications.

internal bowed retaining ring

There are two other important variations of both HO internal rings and SH external rings. The "Bowed" HO (BHO)...

...and "Bowed" SH (BSH), so named because they are shaped like a bow, are used to compensate for accumulated tolerances.

self-locking retaining ring

If the assembly you must retain is characterized by very little thrust load, consider a self-locking retaining ring. These require no groove and are ideal for use on shaft/housing diameters of 1" or less.
