Materials for rings and rolling elements

While the contact surfaces between the bearing rings and rolling elements are subjected to repeated heavy stress,they must still maintain high rotational precission,therefore, the materials used for bearings rings and rolling elements require the following characteristics:

High rolling contact fatigue strength
High hardness
High wear resistance
High dimensional stability
High mechanical strength

2)Materials for cages

The materials for cages must have strength to with stand rotation at load and shock load. Low frictional efficiency light weight and be able to with stand operation temperature.

The material used in ribbon cages or crown cages is 08F or SPCC pressed.

It is chemical compositionis shown for extra-high speed application. Plastic cages such as glass reinforced polymideareused.

These plastic crown have the advantages oflow torque,long grease lefe and low noise,etc.

3)Vibration and noise

The measuring parameter of vibration adopted by RNB is the vibration acceleration of vibration velocity.

 The measuring units and measuring method are specified by JB/T5314 and JB/T5313 In the process of measuring vibration strictly controlled noise by using acoustics.
