Sintered sliding bearing

摘要

A sintered sliding bearing comprises a porous sintered alloy in which the pores in at least the surface layer are filled with a thermoplastic resin with a melt viscosity at 250 DEG C of 10 to 2,000 cPs. The sintered alloy preferably contains a solid lubricant dispersed in the alloy matrix. The bearing is suitable for use at high temperatures, e.g. heating rollers in copying machines.
