6203LLU Deep Groove Ball Bearing

Double row deep groove ball bearings are fitted with two glass fiber reinforced nylon 66 cages. The SKF suffix is TN9.

Deep groove ball bearings fitted with nylon cages can operate at temperatures up to 120 ° C.

The characteristics of the cage are not affected by lubricants used for general rolling bearings, except for certain synthetic or synthetic oil-based greases and lubricants containing large amounts of extreme pressure additives for high temperature applications.

When there is alignment error between the inner and outer rings of double row deep groove ball bearings, additional load will be caused. Thus increase the load of the steel ball and cage, shorten the working life of the bearing. Therefore, the allowable angular error is only 2 arc minutes. Any larger Angle error will result in an increase in noise.
