        3. Slewing bearings


          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.

          Type of slewing rings

          Four point contact ball precision slewing bearing(with inner ring gear,outer ring gear or without gear)

          Double row different diameter ball slewing bearing(with inner ring gear,outer ring gear or without gear)

          Tri-row cylindrical  roller slewing bearing(with inner ring gear,outer ring gear or without gear)

          Crossed roller slewing bearing(with inner ring gear,outer ring gear or without gear)

          Four point ball slewing bearing with

          Slewing dimension

          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.

          Material

          Luoyang jiayu selects the best material specifications to suit specific usages 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.

          Selection and Design

          We can provide bearing type selection and design according to your specific requirements.

          Real-time follow-up

          From raw material procurement to finished product delivery, documented product quality control, factory real-time follow-up

          Complete range

          Various kinds of bearings, including large, super-large turntable bearings, precision cross-roller bearings, thin-walled bearings, precision angular contact ball bearings, ceramic ball bearings, steel wire raceway bearings, joint bearings, etc., have complete accuracy grades.

          High quality and low price

          Because there are factories, we can provide high quality products and guarantee low prices.
