Patent ID: 7651274

Claim:
A spherical slide bearing system, comprising: an outer ring; an inner ring slidably retained within the outer ring; and a pin having a grease supply flow path extending through an interior thereof to open in an outer peripheral surface thereof, the pin being inserted into the inner ring so that the pin is circumferentially slidable therein, and the inner ring including a communication flow path establishing communication between a gap defined between the inner ring and the pin and a gap defined between the inner ring and the outer ring; wherein each of at least one inlet port of the communication flow path in the inner ring is provided at a position that is axially displaced from each of at least one outlet port of the grease supply flow path in the pin so that grease flows through the gap between the pin and the inner ring substantially along an entire axial length of the pin after flowing out of the at least one outlet port of the grease supply flow path and before flowing into the at least one inlet port of the communication flow path.
