Slewing Bearing

Slewing bearing is identical to usual bearings, it assembly simply by rings and rollers. Even so, compare on track bearings, slewing bearing has a lot of dissimilarities. Normally, slewing bearing has huge dimensions, OD usually betwwen 0.4m to 10m, and some even to 40m. Under normal conditions, slewing bearing working in a minimal speed, high load condition. Slewing bearing comes with mounting holes, lubricating holes and sealing unit. It has compact stucture, convenience to guide rotate, simple set up and easy protection etc.

EPT slewing ring bearings can be purchased in many styles with internal, external or perhaps without gear. The low cross section, hefty load ability and integrated equipment make these bearings preferred structure components. Slewing band bearings are widely used in development machinery, mining gear and many other industrial products.
Slewing bearing is a large of bearing with exceptional structure that may bear integrated load like axle load, radial load and overturning load. It combines support, rotating, transmission, fixed, sealed, anti-corrosion and other functions into one device. Trusted in lifting machinery, construction machinery, transmission machinery, mining and metallurgy machinery, medical devices and radar, ship, wind power and additional industries.

Slewing Ring Bearings happen to be precision built to manage a number of load types which includes radial, axial, moment or a combination of each. Their unique construction and small footprint help facilitate simple mounting and protection. Seals are normal for retaining grease and keeping contaminants out. Re-lubricating holes are incorporated into the design, evenly distributed around the bearing, to allow for grease replenishment which facilitates reduce friction and have on and extend bearing lifestyle.
The Single-Row Ball type Slewing Ring have four points with one row. They could bear axial load, radial load and tilting second 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 factors. There happen to be three types of the kind of single row 4 things contact ball slewing bearing: without equipment bearing (non tooth), external gear bearing (exterior tooth), and Internal gear bearing (internal tooth).
EPT slewing band bearings may support radial, axial and tilting minute 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 simple 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 happen to be calculated using software to ensure correct assortment for the slewing bearing. The material selection is done predicated on the type parameters and the necessity of the client. Generally, the materials selected for slew band can be C45 and En19 or 42CrMO4. Excavator and crawler applications in addition to the boom cranes generally have the materials as 50Mn. The balls are created 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 for example heavy equipment, oil and gas, medical systems, renewable energy and semiconductor making. These versatile bearings will be specifically designed to handle large, major, slow-oscillating loads like those in cranes, booms and lifts, yet can be used in high-reliability applications such as CT scanners and professional positioners.
