A method of attaching a sliding member to the bearing ring of a sliding radial bearing device, a sliding radial bearing device, and a rotary work head using the sliding radial bearing device.

摘要

PROBLEM TO BE SOLVED: To improve load bearing property, straight running property and damping property as well as vibration damping property and quietness while utilizing low friction property of a rolling radial bearing device. SOLUTION: A sliding radial bearing device 100 has a bearing ring 130 having a cylindrical inner peripheral surface to be fitted to an outer peripheral surface of a shaft body 110 to be rotationally supported, and a stationary side fitting between the shaft body and the bearing ring. A thin plate-shaped sliding member 10 attached to a surface is provided, and the sliding member includes a lubricating oil pocket 14 whose circumference is surrounded by a land portion 12, and a plurality of convex portions arranged in the lubricating oil pocket. 16 is provided, and lubricating oil is supplied and discharged through the first and second ports 18a and 18b that open into the lubricating oil pocket.
