Friction -aligning the upper and lower idler group used to adjust the belt running side to prevent the snaking to ensure stable operation of the conveyor belt .
The various idlers advanced structure , reliable performance , roll paper timber through a rigorous selection process , the use of high-quality special welded pipe , a strict tolerance requirements . Shaft material using cold drawn round steel, bearing is made of high qualified steel plate stamping , PDC type seal structure , three sealing devices , dustproof, waterproof properties is good. The assembly to roll strength, radial runout quantity is small, the rotary resistance is small, light weight, low energy consumption, long service life.
