Thrust Washers

1. The #50W thrust washer made by our company is a kind of high-performance, solid-lubricated product that is mainly constructed from copper alloy. Different from common bearings, the solid-lubricated thrust washer does not depend on oil film for lubrication.

2. This product allows solid lubricant to rub against axle through frictional heat when in use. It gives outstanding lubrication performance when oil and powder coexist. The thrust washers can not only protect axle from abrasion, but also make the characteristic of solid lubricant permanent.

3. Thus far, the thrust washers have been widely used as the plastic mould accessories, packaging machine accessories, and the other transmission accessories.

4. Please choose the part number through the appropriate inner diameter and thickness. Here is an example under conditions of 6mm inner diameter and 3mm thickness.
