Custom Composite Bearings
The physical properties of CIP Marine™ composites make it an excellent wear and bearing material. As a general guide, this 100% marine bearing material is best suited for high load, high impact and slow rotating applications. CIP Marine™ composite bearings and wear pads are great replacements for your current bronze, brass, nylon, urethane and rubber applications such as rudder, thruster and stern tube bearings.
