Wave Washers, or Wave Spring Washers provide thrust loads and also absorb vibration in applications with little axial space.

These types of Wave Spring Washers are particularly useful for the pre-loading of bearings, for example, in electric motors. The Washers are installed within the bearing housing and operate by maintaining a force on the outer face of the bearing. This ensures a smooth and quiet running of the motor which helps extend the life of the bearing.

The overlap in the Wave Washer allows the end to move during compression.

Need help with installing a Split Cotter Pin correctly?

Here is our helpful guide to provide assistance in ensuring you are using the correct size and installing your split cotter pin correctly.

Here is some helpful information when it comes to fitting Spring Pins, also known as Roll Pins.

Firstly, make sure the spring pin or roll pin is the correct size. These are always listed by the hole size they are fitting in to. For example, a 5mm spring pin, will suit a 5mm hole.

Then make sure the holes in both the Spring Pin, and the hole in your application are aligned accurately so the pin can be inserted smoothly.

Once the pin is aligned to the hole, gently tap the pin in using controlled strikes to avoid misalignment or deformation.

Finally, ensure the pin has a flush fit to the components surface, this will provide a secure connection.

One of the most common issues faced with Roll Pins or Spring Pins, is how to decide what size you require.

However it’s very simple… A Roll Pin or Spring Pin is always listed by the HOLE size it is fitting into. For example if the hole size is 10mm, you will require a 10mm Pin. These Pins are always produced slightly oversized on the outside diameter, to enable them to close down and fit securely into the hole. Using the same size example above, a 10mm Pin will have am outside diameter of 10.5 – 10.8mm, so that it closes down into the 10mm hole.

Each product page on our website for these types of Pins will contain the hole size and the outside diameter measurements to help you decide which Pin you require.
