PURPOSE: To provide a simply structured bearing capable of providing tight sealing to fluids without any wear affecting a sealing ability. CONSTITUTION: A bearing is provided with an inner race 11, an outer race 12, and a rolling member 13 leaving a radial clearance equal to or larger than 0 between the inner and outer races. In one side of the rolling member, a partial sealing member 15 is attached to the inner or outer race to define a substantially annular chamber 17 between the outer or inner race. The substantially annular chamber 17 has a length L and a width (j), and the width (j) is only slightly larger than the radial clearance. |
