ABSTRACT:
A porous-plastic bearing comprises a porous-plastic sliding bearing member which is formed by gathering a cluster of plastic particles each having a volume in the range of from about 0.004 mm.sup.3 to about 4 mm.sup.3 and sintering the cluster of plastic particles while setting its porosity at a selected value in the range of from about 10% to about 30%. Furthermore, the sliding bearing member comprises a plurality of plastic particles in any longitudinal or cross section. Pores formed within the sliding bearing member are impregnated with or filled with a lubricating agent.
