Key Features

Enhanced Rubber Outside Diameter (V)

The outside diameter of the 42X56X7HMSA10V is made of SKF’s fluoro rubber compound (V), also known as viton, which is used in applications where the operating temperature exceeds 100oC (210oF), the upper limit for nitrile rubber. Viton seals can be used in temperatures up to 200oC (390oF). Like the nitrile rubber, these viton seals have extended service lives, reducing the need for maintenance and replacement.
