It is not allowed to press vigorously. It is not allowed to percussion TIMKEN bearings directly with hammers. It is not allowed to transmit pressure through rolling bodies.
Return
Try to use special tools to avoid using cloth and staple.
Even if the invisible smile dust enters TIMKEN bearings, it will increase the wear, vibration and noise of bearings.
When taking the deep groove ball bearings directly with the hand, we should wash the sweat from the hands fully, and then apply the high quality mineral oil to the operation. In the rainy season and summer, we should pay special attention to the rust prevention.
Under some special operating conditions, deep groove ball bearings can get longer life than traditional calculation, especially under light load conditions. These special operating conditions are that when the rolling surface (track and roller) is effectively separated by a lubricating oil film and limits the surface damage that may be caused by the contaminant. In fact, under ideal conditions, the so-called permanent deep groove ball bearing life is not impossible.
(1) at the same time, it is precisely determining the radial target of the shaft and the position of the axial target, and the beating of the stop shaft.
(2) improve the rigidity of the bearing. The machine uses bearings from the axle, differential gear of the bicycle, deep groove ball bearings.
(3) to prevent the vibration of the axially marked target and the homophonic formation due to resonance. Bearings for small motors.
(4) the torsion slip, the revolution slip and the rotation slip of the rolling body. High speed torsion centripetal thrust bearing, thrust ball bearing.
(5) accurate placement of the rings and the rolling elements. Thrust ball bearings and thrust spherical roller bearings are used when the axis is in degree.
