Slewing Bearings

Slewing Bearings

√ The slewing bearing is a large bearing with a special structure that integrates multiple functions such as support, rotation, transmission, and fixation.

√ It is equipped with mounting holes, lubricating oil and sealing device, which can meet various needs

√ Simultaneously bear comprehensive loads such as large axial load, radial load and overturning moment

√ Widely used in a variety of large-scale slewing devices, supporting customization on demand

Slewing Drive

√ The worm-type slewing drive adopts an envelope worm drive, which can obtain a larger reduction ratio

√ Its bearing capacity, deformation resistance and transmission rigidity are higher

√ Suitable for low-speed applications

√ Can quickly customize the design according to customer needs

Spur Gear Drive

Spur Gear Drive

√ It replaces the structure of a toothed turntable and a pinion gear. The compact design can effectively save installation space and is easy to integrate into existing application units.

√ High transmission efficiency, fast speed, can withstand axial, radial and overturning moments

√ The full protection design can effectively extend the service life, reduce maintenance costs, and improve the safety of operators. The protection level reaches IP65
