A rolling bearing for supporting a shaft on which a fan is provided, has an inner ring having an inner ring race on an outer surface thereof, an outer ring having an outer ring race on an inner surface thereof, balls provided between the inner ring race and the outer ring race and a retainer which keeps the balls apart each other in a circumferential direction, wherein an inner diameter of the bearing is set to be 3 mm or more and 17 mm or less, an outer diameter of the bearing is set to be 8 mm or more and 40 mm or less, when a thickness ti and a thickness te satisfies a relationship te&#x2267;1.24 ti, and a residual austenite content in the inner ring is 7 wt % or less.

Rolling element bearing and motor

A pair of pre-loaded ball bearingsare fixed to a shafthaving a flangeto be a reference surface Q formed on one end, and where a clearance C is secured between the surfaceon the flange side of the inner raceof the bearingon the side of the flangeand the flange surface

Rolling bearing apparatus for swing arm

A rolling bearing lubricated with a grease includes an outer ring, an inner ring, a plurality of rolling elements disposed between respective rolling raceway tracks of the outer ring and the inner ring, and a retainer having a plurality of pockets for locking the rolling elements to freely roll and formed of resin material. In the rolling bearing, the radial clearance gap ratio of the pockets of the retainer is set to 0&#x2266;&#x3b4;r/Da&#x2266;0.09, and the axial clearance gap ratio of the pockets is set to 0&#x2266;&#x3b4;a/Da&#x2266;0.06 when the kinematic viscosity of base oil at 40&#xb0; C. of the grease is 10 to 40 mm/sec, being set to 0&#x2266;&#x3b4;a/Da&#x2266;0.05 when the kinematic viscosity of base oil is 10 to 90 mm/sec, being set to 0&#x2266;&#x3b4;a/Da&#x2266;0.025 when the kinematic viscosity of base oil is 10 to 160 mm/sec.

Rolling bearing and fan motor using the same

A one-way clutch containing rolling bearing comprises a bearing part,and an OWC part,sharing an outer race,and an inner race,The bearing part,contains a plurality of balls,and the OWC part,contains sprags,and a ribbon spring,. The balls,and the sprags,are held by a single integral-type cage

One-way clutch containing rolling bearing

A rolling bearing unit comprises outer and inner ring members, a cover having an open and portion fitted to the outer ring member and a rotational speed sensor which is mounted in the cover to detect the rotation of the inner ring member, such that the cover can be removed from the outer ring member without causing any damage on the associated components, by applying a tool to the open end portion of the cover at a recess on the outer ring member faced to the open end portion of the cover.
