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.

Our firm has strived to establish a highly efficient and stable workers workforce and explored an effective high-quality management system for Zys Yrt Series Axial Angular Contact Thrust Bearing Zkldf460 for The Rotary Table of Machine Tool.
