Stern Tube Bearings

Stern tube bearings

For more than 50 years, TENMAT have been manufacturing advanced composite materials for the marine market and supplying more than 8,000 vessels with high-quality FEROFORM and RAILKO bearings on both commercial and military vessels operating in the most adverse environments and giving excellent performance.

TENMAT composite bearings are approved by the major classification societies for use in stern tube, propeller shaft and bracket bearings.

FEROFORM and RAILKO bearings work with any type of water, run with smaller clearances than elastomeric bearings, are dimensionally and thermally more stable, and have superior wear resistance. Independent tests confirm that TENMAT materials have a significantly better wear resistance than elastomeric and polyester / polyester bearing materials from our major competitors.

Therefore ship owners are provided with up to four times longer service life and lower operating costs.
