ACM Composites


Applications above and below the water line

We supply ACM bearings that have been specifically designed for the marine industry in a wide range of applications both above and below the water line.

  • Connector.

    Comprehensive range

    Range includes bearings for rudders and steering gear, water lubricated propeller shafts, anchor handling systems, cranes, winches, stern roller bearings and many other applications.

  • Connector.

    Composite materials

    All bearing feature a composite bearing material that has been specifically formulated for marine environment applications.

  • Connector.

    Dry or lubricated

    Bearings able to run dry in certain applications and with water lubrication in others.

L2 Marine is the primary marine grade supplied and is a high load bearing. It comprises synthetic fabric reinforcement impregnated with a thermosetting resin and solid lubricant fillers. This 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. The range 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. It is for these reasons that many navies use ACM material for their stern shaft bearings.
