Slewing Bearing

Slewing bearing is same as usual bearings, it assembly by rings and rollers. Even so, compare to normal bearings, slewing bearing includes a lot of dissimilarities. Normally, slewing bearing possesses 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 state. 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 can be purchased in many designs with internal, external or Shaft Clamp china perhaps without gear. The reduced cross section, hefty load ability and integrated gear make these bearings ideally suited structure components. Slewing band bearings are widely used in engineering machinery, mining equipment and many other industrial products.
Slewing bearing is a big of bearing with exceptional structure that can bear integrated load like axle load, radial load and overturning load. It combines support, rotating, transmission, fixed, sealed, anti-corrosion and additional functions into one product. Widely used in lifting machinery, engineering machinery, transmission machinery, mining and metallurgy machinery, medical apparatus and radar, deliver, wind power and additional 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 simple mounting and repair. Seals are common for retaining grease and keeping contaminants out. Re-lubricating holes are included into the style, evenly distributed around the bearing, to allow for grease replenishment which can help reduce friction and don 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 minute concurrently. And they are made up of two seat bands, which design in small structure and light-weight, steel ball contact with the circular raceway at four points. There happen to be three types of this kind of single row 4 items contact ball slewing bearing: without equipment bearing (non tooth), external gear bearing (external tooth), and Internal equipment bearing (internal tooth).
EPT slewing band bearings may support radial, axial and tilting second loads performing either singly or perhaps in combination and in any direction. Therefore, you’ll be able to replace the combination arrangement of radial and axial bearings by a single bearing, which will measurably reduce the overall price and simplify the look. Slewing rings are sealed on both sides, lubricated with high quality grease, can be relubricated via lubrication nipples and so are particularly easy to install.

The ball size is normally chosen with respect to the axial load and radial load arriving on the Slewing bearing. It varies from 10 mm to 60 mm. The loads happen to be calculated using software to ensure correct selection for the slewing bearing. The material collection is done predicated on the type parameters and the necessity of the client. Generally, the materials selected for slew ring is usually C45 and En19 or 42CrMO4. Excavator and crawler applications and also the boom cranes generally have the material as 50Mn. The balls are made from High chromium metal, generally denoted by 100Cr6 and the cages are created from either nylon 6 or nylon 66 according to the load conditions.
We makes slewing band bearings for use in a variety of demanding industries such as heavy equipment, oil and gas, medical systems, renewable strength and semiconductor developing. These versatile bearings will be specifically made to handle large, hefty, slow-oscillating loads like those in cranes, booms and lifts, yet can be used in high-reliability applications such as CT scanners and commercial positioners.
