Urethane Washers - Standard, Antistatic, Heat Resistant, Vulkollan®, Abrasion Resistant, Ceramic Urethane, Adhesive
:
MISUMI
We have prepared urethane washers in both inexpensive selection types and free specification types in 1mm increments.
A wide variety of materials are available, including standard urethane (A95, A90, A70, A50, A30), anti-static, and wear-resistant.

[ ! ]Urethane turns yellow by aging, but physical properties and characteristics remain unchanged.
[ ! ] Depending on the lot, milled marks may remain on the sides.
■Characteristic Values of Antistatic Urethane
