Self-lubricating BEARPHITE
By using special graphite and optimizing material composition, we have developed "Self-lubricating BEARPHITE" that can be used in environments not suited to oil lubrication.
Characteristics
- By adding graphite 5 times (or more) than the bronze based material, excellent sliding properties is ensured even in a dry environment.
- Optimized material composition secures formability in manufacturing process
- Has conductivity because it is not oil- impregnated.
