The pressure of Bearing inner is also bigger, and vice versa；
Bearing is improved in the processing efficiency of hard Vehicle Processing age of a draught animal process, and to the inside pressure maintaining of bearing after assembling trap
Detection is can be carried out.
Beneficial effect by adopting the above technical scheme is: having filled up the detection blank about sealing Bearing inner pressure, has increased
The detection means of the internal pressure of sealing bearing is added, and in the process of the bearing age of a draught animal and the bearing age of a draught animal and sealing
Circle matches the evaluation closed and play the role of key；Both improved bearing hard Vehicle Processing age of a draught animal process time processing efficiency and
Quality, and also add after assembly trap to the inside pressure maintaining performance detection means of bearing, meet customer requirement.
