Slewing bearing is identical to ordinary bearings, it assembly by rings and rollers. Even so, compare on track bearings, slewing bearing includes a lot of differences. Normally, slewing bearing has huge dimensions, OD generally betwwen 0.4m to 10m, plus some even to 40m. Under normal conditions, slewing bearing working in a low speed, high load state. Slewing bearing includes mounting holes, lubricating holes and sealing system. It has compact stucture, convenience to steer rotate, simple assembly and easy protection etc.

EPT slewing ring bearings are available in many patterns with internal, Shaft Clamp china external or perhaps without gear. The reduced cross section, hefty load ability and integrated gear make these bearings great structure components. Slewing band bearings are trusted in construction machinery, mining equipment and many other industrial products.
Slewing bearing is normally a big 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 device. Widely used in lifting machinery, building machinery, transmitting machinery, mining and metallurgy machinery, medical devices and radar, ship, wind power and additional industries.

Slewing Ring Bearings happen to be precision created to manage a range of load types including radial, axial, moment or a combination of every. Their particular construction and compact footprint help facilitate simple mounting and repair. Seals are typical for retaining grease and keeping contaminants out. Re-lubricating holes are included into the style, evenly distributed around the bearing, to permit for grease replenishment which assists reduce friction and have on and extend bearing existence.
The Single-Row Ball type Slewing Ring have four points with one row. They could bear axial load, radial load and tilting minute as well. And they are composed of two seat bands, which design in small structure and light weight, steel ball contact with the circular raceway at four things. There happen to be three types of this kind of single row 4 points contact ball slewing bearing: without gear bearing (non tooth), exterior gear bearing (external tooth), and Internal equipment bearing (internal tooth).
EPT slewing ring bearings may support radial, axial and tilting instant loads performing either singly or perhaps in combination and in virtually any direction. Therefore, it is possible to replace the combination set up of radial and axial bearings by a single bearing, that will measurably reduce the overall cost and simplify the design. Slewing rings will be sealed on both sides, lubricated with top quality grease, can be relubricated via lubrication nipples and are particularly easy to install.

The ball size is generally chosen with regards to the axial load and radial load arriving on the Slewing bearing. It varies from 10 mm to 60 mm. The loads are calculated using software to ensure correct collection for the slewing bearing. The material collection is done based on the suggestions parameters and the requirement of the client. Generally, the materials selected for slew band is certainly C45 and En19 or 42CrMO4. Excavator and crawler applications in addition to the boom cranes generally possess the materials as 50Mn. The balls are constructed of High chromium steel, generally denoted by 100Cr6 and the cages are created from either nylon 6 or nylon 66 based on the load conditions.
We makes slewing band bearings for use in various demanding industries such as for example heavy equipment, coal and oil, medical systems, renewable energy and semiconductor developing. These versatile bearings are specifically designed to handle large, major, slow-oscillating loads like those in cranes, booms and lifts, yet can be used in high-accuracy applications such as for example CT scanners and professional positioners.
