ACM L2 Marine is a high load composite bearing material that has been specifically formulated for marine environment applications.
With virtually zero swell in water and very low thermal expansion coefficients, L2 Marine is ideally suited to the operating conditions and working environment of rudder and pintle bearings which can be either water, oil, grease lubricated or dry conditions. The material was developed to give improved performance, longer life, non-lubricated operation and a maintenance free fit and forget bearing solution.
Advantages
- High load capability
- Dry, grease, oil or water lubricated
- Very low swell
- Can be freeze fitted
- Short delivery time
- Low wear
- Shaft friendly
L2 Marine is the only composite material approved to operate as a rudder bearing in wet and dry conditions at bearing pressures up to 10 MPa. Class approvals are held from many of the world’s foremost classification societies.
ACM L2 Marine has been tested and approved for stern tube bearing applications and has been proven to offer superior performance in terms of wear, extended life and low shaft wear over other water lubricated propeller shaft bearing materials.
Key Properties
- Classification society approved
- Dynamic coefficient of friction (dry): 0.13
- Swell in water (volume): < 0.15%
ACM has extensive experience supplying L2 Marine bearings for the marine and offshore industry in a wide range of applications including rudder bearings and steering gear, water lubricated propeller shaft bearings, bearings for anchor handling systems, crane bearings, life boat systems, winches, stern roller bearings, offshore moorings and so on. ACM L2 Marine has been successfully installed and operated on over 7,000 vessels worldwide.
