Slewing bearing is same as common bearings, it assembly by rings and rollers. Nevertheless, compare to normal bearings, slewing bearing has a lot of differences. Normally, slewing bearing provides huge dimensions, OD usually betwwen 0.4m to 10m, plus some even to 40m. Under normal situations, slewing bearing functioning in a minimal speed, high load state. Slewing bearing includes mounting holes, lubricating holes and sealing gadget. It has small stucture, convenience to steer rotate, simple assembly and easy repair etc.
EPT slewing ring bearings can be purchased in many designs with internal, external or without gear. The reduced cross section, weighty load potential and integrated gear make these bearings great structure components. 
Slewing ring bearings are widely used in construction machinery, mining tools and many other industrial products.
Slewing bearing is normally a big of bearing with distinctive structure that may bear integrated load just 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, engineering machinery, transmission machinery, mining and metallurgy machinery, medical gear and radar, ship, wind power and various other industries.
Slewing Ring Bearings happen to be precision created to manage a range of load types which include radial, axial, moment or a combination of every. Their particular construction and small footprint help facilitate ease of 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 facilitates reduce friction and use 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 moment as well. And they are made up of two seat rings, which design in small structure and light-weight, steel ball contact with the circular raceway at four details. There happen to be three types of this sort of single row 4 items contact ball slewing bearing: without gear bearing (non tooth), external gear bearing (exterior tooth), and Internal equipment bearing (internal tooth).
EPT slewing band bearings may support radial, axial and tilting minute loads acting 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, that may measurably reduce the overall price and simplify the design. Slewing rings are sealed on both sides, lubricated with top quality grease, could be relubricated via lubrication nipples and are particularly simple to Shaft Clamp china 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 will be calculated using software to ensure correct selection for the slewing bearing. The material variety is done based on the input parameters and the requirement of the customer. Generally, the materials selected for slew band is normally C45 and En19 or 42CrMO4. Excavator and crawler applications in addition to the boom cranes generally have the material as 50Mn. The balls are constructed with High chromium metal, generally denoted by 100Cr6 and the cages are made from either nylon 6 or nylon 66 based on the load conditions.
We makes slewing band bearings for use in a range of demanding industries such as for example heavy equipment, coal and oil, medical systems, renewable strength and semiconductor production. These versatile bearings will be specifically designed to handle large, heavy, slow-oscillating loads like those in cranes, booms and lifts, yet can even be used in high-reliability applications such as CT scanners and professional positioners.
