ABSTRACT:
A bush with a sliding surface comprising a socket, a ball-integral shaft having shaft portions on both sides of a ball portion, a bearing body location between the socket and the ball-integral shaft, and a cushion having recesses in at least one axial end portions thereof constructed of polyurethane resins or polyester resins. Excellent absorption of manufacturing tolerances of parts of the bush and easy adjustment of rotational torque of the bush in normal operating conditions are obtained through use of the bush of the present invention. Additionally, the bush can show excellent load bearing characteristics even when the bush receives large loads beyond normal operating loads. Further, the durability of the bush is improved.
