Slewing bearing is same as ordinary bearings, it assembly by rings and rollers. Nevertheless, compare on track bearings, slewing bearing includes a lot of distinctions. Normally, slewing bearing has huge dimensions, OD usually betwwen 0.4m to 10m, and some even to 40m. Under normal circumstances, slewing bearing working in a low speed, high load state. Slewing bearing comes with installation holes, lubricating holes and sealing machine. It has small stucture, convenience to guide rotate, simple set up and easy maintenance etc.

EPT slewing ring bearings are available in many designs with internal, external or perhaps without gear. The reduced cross section, heavy load capacity and integrated equipment make these bearings best structure components. Slewing ring bearings are widely used in building machinery, mining apparatus and many other industrial products.
Slewing bearing is a sizable of bearing with special structure that can bear integrated load just like axle load, radial load and overturning load. It combines support, rotating, transmitting, fixed, sealed, anti-corrosion and additional functions into one device. Trusted in lifting machinery, engineering machinery, transmitting machinery, mining and metallurgy machinery, medical equipment and radar, deliver, wind power and additional industries.

Slewing Ring Bearings are precision built to manage many different load types which includes radial, axial, moment or a combination of each. Their particular construction and small footprint help facilitate ease of mounting and repair. Seals are normal for retaining grease and keeping contaminants out. Re-lubricating holes are incorporated into the style, evenly distributed around the bearing, to allow for grease replenishment which can help reduce friction and wear 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 instant at the same time. And they are made up of two seat rings, which design in small structure and light weight, steel ball connection with the circular raceway at four items. There will be three types of the kind of single row 4 details get in touch with ball slewing bearing: without equipment bearing (non tooth), exterior 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 perhaps in combination and in virtually any direction. Therefore, Shaft Clamp china 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 design. Slewing rings are sealed on both sides, lubricated with high 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 arriving on the Slewing bearing. It varies from 10 mm to 60 mm. The loads will be calculated using software to make sure correct variety for the slewing bearing. The material selection is done based on the type parameters and the necessity of the client. Generally, the materials selected for slew band is certainly C45 and En19 or 42CrMO4. Excavator and crawler applications as well as the boom cranes generally possess the materials as 50Mn. The balls are constructed with High chromium steel, generally denoted by 100Cr6 and the cages are constructed of either nylon 6 or nylon 66 depending on the load conditions.
We makes slewing ring bearings for use in a range of demanding industries such as heavy equipment, coal and oil, medical systems, renewable energy and semiconductor developing. These versatile bearings happen to 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 for example CT scanners and industrial positioners.
