Slewing bearing is identical to ordinary bearings, it assembly by rings and rollers. On the other hand, compare on track bearings, slewing bearing has a lot of dissimilarities. Normally, slewing bearing provides huge dimensions, OD usually betwwen 0.4m to 10m, plus some even to 40m. Under normal circumstances, slewing bearing operating in a low speed, high load condition. Slewing bearing includes installation holes, lubricating holes and sealing machine. It has small stucture, convenience to steer rotate, simple assembly and easy maintenance etc.

EPT slewing band bearings are available in many styles with internal, external or without gear. The low cross section, serious load ability and integrated gear make these bearings best structure components. Slewing band bearings are widely used in structure machinery, mining tools and many other industrial products.
Slewing bearing is a large of bearing with unique structure that could bear integrated load like axle load, radial load and overturning load. It combines support, rotating, transmitting, fixed, sealed, anti-corrosion and different functions into one product. Trusted in lifting machinery, engineering machinery, transmitting machinery, mining and metallurgy machinery, medical equipment and radar, ship, wind power and other industries.

Slewing Ring Bearings happen to be precision built to manage various load types which include radial, axial, moment or a combination of each. Their particular construction and compact footprint help facilitate simple mounting and repair. Seals are standard for retaining grease and keeping contaminants out. Re-lubricating holes are incorporated into the design, evenly distributed around the bearing, to permit for grease replenishment which allows reduce friction and dress in and extend bearing existence.
The Single-Row Ball type Slewing Band have four points with one row. They could bear axial load, radial load and tilting instant as well. And they are made up of two seat bands, which design in compact structure and light-weight, steel ball contact with the circular raceway at four points. There are three types of this kind of single row 4 details speak to ball slewing bearing: without gear bearing (non tooth), external gear bearing (external tooth), and Internal gear bearing (internal tooth).
EPT slewing band bearings may support radial, axial and tilting instant loads acting either singly or in combination and in any direction. Therefore, you’ll be able to replace the combination set up of radial and axial bearings by a single bearing, which will measurably decrease the overall cost and simplify the look. Slewing rings are sealed on both sides, lubricated with top quality grease, could be relubricated via lubrication nipples and are particularly easy to install.

The ball size is normally chosen with regards to the axial load and radial load approaching on the Slewing bearing. It varies from 10 mm to 60 mm. The loads happen to be calculated using software to make sure correct variety for the slewing bearing. The material selection is done predicated on the insight parameters and the requirement of the client. Generally, the materials selected for slew ring is certainly C45 and En19 or 42CrMO4. Excavator and crawler applications plus the boom cranes generally possess the material as 50Mn. The balls are created from High chromium metal, generally denoted by 100Cr6 and the cages are constructed with either nylon 6 or nylon 66 based on the load conditions.
We makes slewing ring bearings for use in a number of demanding industries such as heavy equipment, coal and oil, medical systems, renewable energy and semiconductor making. These versatile bearings will be specifically made to handle large, heavy, slow-oscillating loads like those in cranes, booms and lifts, yet can even be used in high-reliability applications such as for example CT scanners and professional positioners.
