Custom Cast Urethane WasherShanghai Pepsen manufactures standard and custom urethane washers as per customer requirements including drawings or samples. Hardness is normally 40A-70D, but can vary as well as color. 


What are the types of urethane washers?

Washers usually come as thin and flat disc with a central hole. Depending on the intermediary material, washers can be used to distribute the load such as a screw or a nut, reduce vibration and noise, prevent corrosion of oil and chemical, or be applied as a spacer, spring, wear pad, locking device, or seal.

There are generally three types of urethane washers: flat washers, spring washers, and locking washers.

Plain/flat washers distribute the weight to keep the surface from being damaged or to provide electrical insulation.

Spring washers are flexible enough to prevent a fastening from loosening due to intense vibration.

A locking washer can also act as a spring washer; locking washers prevent materials (like a nut/bolt) from coming loose.

What applications for urethane washers?

Urethane washers are famous for their high tear strength, excellent wear resistance, and very suitable for sealing and cushioning. Used in a variety of industries including punching die, drinking water, electrical and automotive, urethane washers are small, but very important to the function of many engineering applications.
