Abstract: The present invention provides a plain bearing having improved bearing properties, especially anti-seizure property, initial conformability and cavitation resistance. According to the present invention, a sliding layer is provided on a surface of a bearing alloy layer comprising of a copper-based or aluminum-based alloy, thereby the sliding layer is so structured that, to a polyamide-imide resin of a main constituent, a polyamide resin is added and mixed under a high shear force to form a polymer-alloyed resin binder, in which 1 to 75% by mass of a solid lubricant is dispersed. The sliding layer can have high toughness and strength, as well as improved anti-seizure property, initial conformability and cavitation resistance.

Abstract: A bearing seal suitable for sealing a bearing system (18) under extremely abrasive and damp conditions. The seal assembly (22) includes a metal casing (36) received in a housing (26) which defines a small annular gap (34) relative to a shaft (16) supported by the bearing system (18). The seal assembly (22) includes a first seal (42) and a second seal (48) spaced apart to define an annular space (60). The assembly (22) is provided with a plurality of passages (64/66) circumferentially spaced apart from one another. Upon pumping grease (76) under pressure into the bearing system, grease is forced to flow through the passages (64/66) whereby the annular gap (34) is filled with grease throughout substantially the entire circumference thereof. The mass of grease retained in the annular gap (34) serves as a barrier against water and abrasive particles. A bearing and seal assembly (10) is also disclosed.
