Edabearings import bearings, if not choose wrong was correctly used, prior to bearing life, can be used for a long time, in this case, the damage to split.
Injury status: the bearing load when rotating, the inner ring, outer ring raceway surface rolling or peeling phenomenon decent due to rolling fatigue and showed scaly. Cause: excessive load. Install side (non linear) torque load, water intrusion. Poor lubrication, lubricant inappropriate bearing clearance is not appropriate. Bearing box accuracy is not good, the rigidity of bearing box uneven axial deflection of large rust, erosion point, scratch and indentation (surface deformation) causes the development.

The use of appropriate viscosity lubricant, improve lubrication method. Check the shaft and bearing box accuracy. Check the clearance. Check the clearance.
According to the load direction, acting on the Edabearings bearing imports and the nature of the inner and outer rings which side of each ring rotation, the load can be divided into the rotating load, static load or non directional load. Under the rotating load and non directional loads shall be taken with the (static ring interference fit), static load bearing ferrule, desirable transition fit or movable fit (clearance).
Edabearings imports the bearing load or impact load, vibration, the surplus shall be increased. The hollow shaft, thin-wall bearing box or light alloy, plastic housings, also need to increase the amount of interference.
The requirement to maintain high rotation, should be used in high precision bearings, and improve the dimensional precision of shaft and bearing box, to avoid interference is too large. If the interference is too large, may make the shaft or bearing box geometry precision of bearing ring geometry, to the detriment of the rotating precision bearings.
Non separable bearings (such as deep groove ball bearing inner ring and the outer ring of the static with), Edabearings imports bearing installation, disassembly is extremely inconvenient, the inner and outer rings of the best one side adopts the movable fit.
