Thrust Washers

Posted by - ratite Dec/07/2006 at 09:36AM

I use them where ever there is pressure and two twisting or rotating surfaces.

What happens when you compress a compression spring is the spring will rotate back and forth as you compress and release

When you install a Thrust Washers it acts as a bearing (I use this term lightly) the washer is precision ground and hardened and intended as a bearing race for the Thrust bearing.

If you install a needle thrust bearing sandwiched between 2 washers at the end of a spring you have a very smooth spring function it allows the spring to move freely without fiction.

A washer is good at both ends of the spring and a bearing is better at one end.
RWS use 2 washers and oil (NOT GREASE) on their upper end springers I would think RWS knows what there doing.
