ACM Bearings Ltd have been manufacturing resin bonded composite materials for many years.
Our current customer base is very extensive, ranging from forklift truck manufacturers to nuclear power generation; food processing to pharmeceuticals.
L2 Marine has classification society approvals, and ACM Bearings Ltd are ISO 9001:2000 approved.
The material is available in tube and sheet form, as well as in fully finished components to customer or ACM drawings.
L2 Marine has been specifically formulated for marine environment applications. It is ideally suited to the operating conditions and working environment of rudder and pintle bushes, which can be either water, oil or grease lubricated, or be operating under dry conditions.
The material is a high load composite bearing material made of synthetic fabric reinforcement which is impregnated with a thermosetting resin and solid lubricant fillers (molybdenum disulphide & ptfe).
L2 Marine has approval with Lloyd's Register of Shipping for use as a synthetic rudder bearing material, for a bearing pressure of 5.5Nmm-2 under wet and dry conditions, and for a bearing pressure of 10Nmm-2 under wet and dry conditions.
ACM is also a Germanischer Lloyd approved manufacturer of rudder and pintle bearing bushes in L2 Marine under wet and dry conditions.
Other approvals are available, certifying the material for rudder bearing and pintle applications.
The material is grey in colour and is available in tube and sheet form, as well as in fully finished components to customer or ACM drawings.
The material is manufactured to documented procedures and propriety standards. Certificates of conformance can be issued and full traceability is kept for 5 years.

Housing: ACM marine bearings require radial support from the bearing housing. Under normal operating conditions the interference fit quoted is adequate to retain the bearing in its housing. The use of a retaining ring or a shouldered housing bore is recommended and lead-in chamfers are required on the bearing to prevent shaving of the bearing during press fitting.
Shaft: The external diameter of the shaft should be constant over the length of the bearing operating surface. The surface finish should be a maximum of 1.2 µRa.
