What causes the cross roller bearing fault vibration?

The cross roller bearing fault vibration fault vibration is mainly caused by the following reasons:

1) Excessive load causes excessive deformation of inner and outer rings and rolling body, resulting in vibration - transmission vibration caused by the change of center of rotary axis of cross roller bearing with rolling body position, as well as vibration caused by inaccurate installation or different sizes of rolling body. Generally, such vibration is of low frequency.

2) Nonlinear vibration due to poor lubrication of grease.

3 tips: How to judge there are safety hazards in bearing operation by watching and listening?

Bearing is an indispensable part in the mechanical industry, and the quality of bearing affects the operation performance of machinery.We usually is removed bearing for testing, Today FRB BEARINGS teach you new skills: How to judge there are safety hazards in bearing operation by watching and listening?

Observation: should open the bearing box on a regular basis, in order to visual check bearing and oil seal, check of the condition of the near the bearing oil seal to ensure that they are enough to prevent hot liquids or corrosive liquid, gas along the axis of seeping into the bearings.

Be careful !！Six big failure of bearings

 

Bearing is the core part of mechanical . We can check the fault of bearing timely to ensure the normal operation of machinery.Now let's look at six big failure of bearings.

1.Fatigue
Bearing fatigue is characterized by spalling of bearing raceway.This is because the strength of the bearing steel particles decreases, causing the particles to peel off the raceway.The surface of the cracked bearing is rough, which will produce noise and vibration.

Normal fatigue damage occurs when the bearing reaches its expected life under normal load and working conditions.This form of damage is predictable and is caused by metal damage under continuous load.
