WH series for heavy duty rotary drive.The surface adopts QPQ treatment process, which can not only increase the surface hardness of the product, but also ensure its wear resistance and corrosion resistance.
.
On the basis of the original product, 8 bolts are added at both ends of the worm to effectively prevent the worm from being pulled out due to the excessive axial impact force.
Different from the traditional 42CrMo worm material, carbon steel is added to ensure that the worm can bear the input torque of 600-1000N. M
WH14 slewing drive rotary table is widely used in aerial work platform, roadheader, rotating equipment and automatic assembly line.


For Coresun Drive’s slewing drive worm bearing, raw material testing, process testing, finished product testing should be made for ensuring the 100% quality production.

These initiatives include the availability of customized designs with speed and dispatch for Waterproof/ High Speed/ Wholesale/ Rotary Table Bearing. 'Reputation is life, quality and survival'.
