3) Good anti-dust effect
Dust seal structure is different with the previous structure. It adopts a method that combines the dust seals made of special material and air curtain, which has good anti-dust effect.
4) Convenient adjustment and maintenance
The upper bearing is spherical bearing, which makes the shaft run more stable, and the load capacity is higher, thereby prolonging the service life. Besides, the spherical bearing inner ring is shaft bushing structure, the maintenance is easier.
Be equipped with gap measuring device, the crushing can be adjusted by hydraulic device through button operation in short time.
