Curved spring washers
Do (mm): 5.46 - 31.12
Di (mm): 2.54 - 20.32
t (mm): 0.10 - 0.53
Precision engineered curved washers are available in many stock sizes. These washers are made of finely tempered spring steel with some sizes being made of stainless steel. They came deburred and have had all set removed during manufacture. Curved washers exert relatively light thrust loads and are often used to absorb axial end play.
The rate is approximately linear between 10% and 80% of available deflection.
Standard finish for high carbon steel is plain finish. Stainless steel is supplied in plain finish. On special order, high carbon steel washers may be mechanically plated, a process which substantially reduces the possibility of hydrogen embrittlement.
