Slewing bearing is same as usual bearings, it assembly by rings and rollers. Even so, compare on track bearings, slewing bearing has a lot of dissimilarities. Normally, slewing bearing has huge dimensions, OD generally betwwen 0.4m to 10m, plus some even to 40m. Under normal circumstances, slewing bearing working in a minimal speed, high load condition. Slewing bearing includes mounting holes, lubricating holes and sealing unit. It has compact stucture, convenience to steer rotate, simple installation and easy repair etc.

EPT slewing ring bearings are available in many models with internal, external or perhaps without gear. The low cross section, major load capacity and integrated equipment make these bearings best structure components. Slewing band bearings are widely used in construction machinery, mining gear and many other industrial products.
Slewing bearing is definitely a huge of bearing with specialized structure that could bear integrated load like axle load, radial load and overturning load. It combines support, rotating, tranny, fixed, sealed, anti-corrosion and various other functions into one unit. Trusted in lifting machinery, structure machinery, tranny machinery, mining and metallurgy machinery, medical equipment and radar, ship, wind power and various other industries.

Slewing Ring Bearings will be precision built to manage a number of load types which includes radial, axial, moment or perhaps a combination of each. Their unique construction and small footprint help facilitate ease of mounting and repair. Seals are regular for retaining grease and keeping contaminants out. Re-lubricating holes are included into the design, evenly distributed around the bearing, to permit for grease replenishment which can help reduce friction and use and extend bearing life.
The Single-Row Ball type Slewing Band have four points with one row. They could bear axial load, radial load and tilting second simultaneously. 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 happen to be three types of the kind of single row 4 items speak to ball slewing bearing: without equipment bearing (non tooth), external gear bearing (external tooth), and Internal equipment bearing (internal tooth).
EPT slewing ring bearings can support radial, axial and tilting instant loads performing either singly or perhaps in combination and in virtually any direction. Therefore, you’ll be able to replace the combination set up of radial and axial bearings by an individual bearing, that will measurably reduce the overall price and simplify the design. Slewing rings happen to be sealed on both sides, lubricated with top Shaft Clamp china quality grease, can be relubricated via lubrication nipples and so are particularly easy to install.

The ball size is generally chosen with respect to the axial load and radial load approaching on the Slewing bearing. It varies from 10 mm to 60 mm. The loads are calculated using software to ensure correct variety for the slewing bearing. The material assortment is done based on the source parameters and the necessity of the client. Generally, the material selected for slew band can be C45 and En19 or 42CrMO4. Excavator and crawler applications plus the boom cranes generally have the materials as 50Mn. The balls are constructed with High chromium metal, generally denoted by 100Cr6 and the cages are constructed of either nylon 6 or nylon 66 according to the load conditions.
We makes slewing band bearings for use in a number of demanding industries such as for example heavy equipment, oil and gas, medical systems, renewable energy and semiconductor manufacturing. These versatile bearings happen to be specifically designed to handle large, heavy, slow-oscillating loads like those in cranes, booms and lifts, yet can even be used in high-accuracy applications such as CT scanners and industrial positioners.
