Slewing bearing is same as regular bearings, it assembly simply by rings and rollers. However, compare on track bearings, slewing bearing has a lot of dissimilarities. Normally, slewing bearing possesses huge dimensions, OD generally betwwen 0.4m to 10m, plus some even to 40m. Under normal conditions, slewing bearing functioning in a minimal speed, high load condition. Slewing bearing includes mounting holes, lubricating holes and sealing gadget. It has compact stucture, convenience to guide rotate, simple unit installation and easy protection etc.
EPT slewing band bearings can be found in many styles with internal, external or without gear. The reduced cross section, heavy load capability and integrated equipment make these bearings best structure components. Slewing band bearings are widely used in building machinery, mining apparatus and several other industrial products.
Slewing bearing can be a big of bearing with specialized structure that may bear integrated load like axle load, radial load and overturning load. It combines support, rotating, tranny, fixed, sealed, anti-corrosion and other functions into one unit. Widely used in lifting machinery, building machinery, tranny machinery, mining and metallurgy machinery, medical devices and radar, ship, wind power and other industries.
Slewing Ring Bearings happen to be precision built to manage a variety of load types which include radial, axial, moment or a combination of every. Their particular construction and small footprint help facilitate simple mounting and repair. Seals are regular for retaining grease and keeping contaminants out. Re-lubricating holes are integrated into the design, evenly distributed around the bearing, to allow for grease replenishment which assists reduce friction and have on and extend bearing lifestyle.
The Single-Row Ball type Slewing Band have four points with one row. They could bear axial load, radial load and tilting second at the same time. And they are composed of two seat rings, which design in small structure and light-weight, steel ball connection with the circular raceway at four tips. There will be three types of the sort of single row 4 points get in touch with ball slewing bearing: without equipment bearing (non tooth), external gear bearing (external tooth), and Internal equipment bearing (internal tooth).
EPT slewing ring bearings can support radial, axial and tilting minute loads acting either singly or perhaps in combination and in any direction. Therefore, it is possible to replace the combination set up of radial and axial bearings by a single bearing, that will measurably decrease the overall expense and simplify the look. Slewing rings are sealed on both sides, lubricated with top quality grease, can be relubricated via lubrication nipples and 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 are calculated using software to make sure correct selection for the slewing bearing. The material variety is done based on the input parameters and the requirement of the client. Generally, the material selected for slew ring is definitely 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 of High chromium metal, generally denoted by 100Cr6 and the cages are made of either nylon 6 or nylon 66 based on the load conditions.
We makes slewing band bearings for use in various demanding industries such as heavy equipment, coal and oil, medical systems, renewable strength and semiconductor making. These versatile bearings happen to be specifically made to handle large, serious, slow-oscillating loads like those in cranes, booms and lifts, yet may also be used in high-precision applications such as CT scanners and industrial positioners.
