A patent application has been granted for the taper locking key design of Orkot® Marine Bearings’, part of Trelleborg Sealing Solutions in Rotherham, stern tube bearings manufactured in two material grades for commercial and naval vessels. The expanding key is a mechanical fixing option to bearing assembly by press fitting or chocking. This design allows for removal of the bearings without dry-docking the vessel.
The grants are UK Patent Application GB 0617761.2 and European Patent Application EP 07 253 533.9 and the low-wear low-friction propeller shaft bearings may be up to 1m diameter. They have all major classification society approvals at 2:1 length to diameter ratio and can be used as conventional water lubricated stern tube bearings or as A bracket bearings for naval ships.
