SE Single Worm Gear Slewing Ring Bearing With Hydraulic Motor For
Construction Machinery
Single Worm Gear Slewing Drive
Hangtuo make all kinds of slewing bearings for construction
machinery, such as tower cranes, excavator, mobile crane, crawler
crane, stacker reclaimers. Our compact designed worm gear slewing
drives are specially for solar tracking systems. We are capable to
design and manufacture non-standard slewing bearing and slewing
drives independently. Our products are widely used in various
application fields, such as port, ship, vehicle, mining,
engineering, lifting, environmental protection, oil, chemicals,
light industry, metallurgical machinery and the military etc. With
over 10 years of experience, our products are widely export to USA,
Germany, Japan, Spain, Canada, Italy, France, India, Brazil,
Australia etc.
