Oiles 470-02/02W Carbon fiber composite bearings for underwater use Feature Has self-lubricating performance. Demonstrates low coefficient of friction and superior wear performance especially in water, chemicals, or oil. Demonstrates superior wear performance and maintains stable performance even under abrasive conditions subject to soil, sand, foreign matter or rust on the mating parts. A multi-layer type (470-02W), which incorporates 470-02 on the sliding surface and 250 or 425 as the backing material is also available. The standard split metal for flocculators and bearing units are available on order.
