Precision dual axis slewing bearing slewing drive for solar tracking system

According to rows of rolling elements,slewing bearings can be divided into single-row slewing bearings, double -row slewing bearings and multi-row slewing bearings. Slewing bearings also can be divided into roller slewing bearings  and  ball slewings depending on rolling element type.Slewing bearings are also called rotary ring bearings,slewing rings or turntable rings which are usually used in these indusitries,such as port machine, metallurgical industry ,hoist and engineering machine, and so on. Luoyang Jiayu not only provide not only solutions for those applications,but also high-level slewing bearings research and development so that we can offer high precision slewing bearings.

We can produce whole slewing bearings with a diameter from 120mm up to 13000mm. In terms of segmented bearings, these are manufactured with a diameter of up to 17 metres.When manufacturing slewing bearings. The material we choose mostly is 42CrMo,but sometimes structural hardening steels or alloys, special steels for hardening under controlled atmosphere.These materials are manufactured by approved steel works. Inspections are carried out at each significant step of manufacturing what makes it possible to achieve the specified quality. Core hardening and tempering are carried out to reach required hardness.

The slewing drive is a new type of slewing product, usually called slewing ring, which is usually composed of worm, slewing ring, housing, motor and other components. Since the core components are slewing bearings, they can simultaneously withstand axial forces, radial forces, and overturning moments. Compared with traditional rotary products, the new rotary drive features easy installation, easy maintenance and a greater degree of installation space.

Slewing drive are widely used in PV,CPV,STP solar tracking systems and construction applications including truck cranes, manlifts, turntables, port machinery, modular vehicles, small wind power systems and satellite communications.

Coresun Drive processes the Slewing Drive Motor metallographic testing to ensure the quality of raw material and follows the standard inspection specification.
