Bearing friction torque decreases with the increase of cage pocket hole clearance, this basically is by the cage pocket hole clearance will reduce with the increasing of steel ball and cage pocket hole.
Caused by the friction between, so for oil bearing cage angular contact ball bearing bearing.
Cage pocket hole clearance should be taken into account in the cage before running smoothness Take appropriate way.
Bearing friction torque as the cage guide clearance and decreases, when the cage guide gap increases to a certain value,bearing friction torque increases with the increase of cage guide clearance.
Under the condition of bearing low speed, ball and cage.
It is difficult to form between elastohydrodynamic lubrication, basic in dry friction condition,therefore, square column type straight pocket hole cage of angular contact ball bearing friction.
Torque than cylindrical straight pocket hole cage bearing friction torque is small, but under the condition of bearing at high speed, the axis of the cylindrical straight hole bag cage.
Bearing friction torque than square column type straight hole cage bearing friction torque small, this is because the cylinder bore straight pocket than square column type straight pocket in the steel ball.
