[Note]

1. Polyoxymethylene (POM) resin is used in conjunction with steel, and can be used without lubrication or with lubrication. Lubrication can effectively improve PmV value and wear.

2. The temperature of polyoxymethylene (POM) resin changes greatly. When using it, please pay attention to the use temperature, frictional heat, etc.

3. The friction coefficient changes according to the use conditions and lubrication conditions.
