Abstract A sleeve bearing is described which is useful for carrying the rotating propellor shaft of water craft, as well as for various industrial purposes. The sleeve bearing consists of a single homogeneous solid, hard elastomeric urethane polymer having a Shore D hardness of at least 60, a compressive modulus of elasticity at a 4% compressive strain of at least 50,000 psi and a dry dynamic co-efficient of friction against steel of no more than 0.20. This polymer is machined so as to fit within a cylindrical housing by means of a forced interference fit providing sufficient outward radial force by the outer surface of the sleeve on the housing to retain the bearing in movement-free fit during the operational life of the bearing.
