Slewing bearing is same as normal bearings, it assembly by rings and rollers. However, compare to normal bearings, slewing bearing has a lot of dissimilarities. Normally, slewing bearing has huge dimensions, OD generally betwwen 0.4m to 10m, plus some even to 40m. Under normal conditions, slewing bearing operating in a minimal speed, high load condition. Slewing bearing comes with mounting holes, lubricating holes and sealing unit. It has compact stucture, Shaft Clamp china convenience to guide rotate, simple installation and easy maintenance etc.
EPT slewing band bearings are available in many designs with internal, external or without gear. The reduced cross section, large load capacity and integrated gear make these bearings great structure components. Slewing band bearings are widely used in engineering machinery, mining products and many other industrial products.
Slewing bearing is certainly a huge of bearing with particular structure that may bear integrated load just like axle load, radial load and overturning load. It combines support, rotating, tranny, fixed, sealed, anti-corrosion and various other functions into one product. Trusted in lifting machinery, structure machinery, tranny machinery, mining and metallurgy machinery, medical equipment and radar, deliver, wind power and other industries.
Slewing Ring Bearings are precision created to manage a range of load types which include radial, axial, moment or a combination of each. 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 allows reduce friction and use 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 minute simultaneously. And they are made up of two seat bands, which design in compact structure and light-weight, steel ball connection with the circular raceway at four details. There are three types of this kind of single row 4 factors contact ball slewing bearing: without equipment bearing (non tooth), exterior gear bearing (exterior tooth), and Internal equipment bearing (internal tooth).
EPT slewing band bearings may support radial, axial and tilting moment loads acting either singly or in combination and in any direction. Therefore, you’ll be able to replace the combination set up of radial and axial bearings by an individual bearing, that may measurably reduce the overall cost 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 easy to install.
The ball size is normally chosen with respect to the axial load and radial load coming on the Slewing bearing. It varies from 10 mm to 60 mm. The loads will be calculated using software to make sure correct collection for the slewing bearing. The material assortment is done based on the suggestions parameters and the requirement of the customer. Generally, the materials selected for slew ring is definitely C45 and En19 or 42CrMO4. Excavator and crawler applications along with the boom cranes generally possess the materials as 50Mn. The balls are made of High chromium metal, generally denoted by 100Cr6 and the cages are constructed of either nylon 6 or nylon 66 according to the load conditions.
We makes slewing band bearings for use in a range of demanding industries such as heavy equipment, coal and oil, medical systems, renewable energy and semiconductor making. These versatile bearings happen to be specifically designed to handle large, weighty, slow-oscillating loads like those in cranes, booms and lifts, yet can even be used in high-reliability applications such as for example CT scanners and professional positioners.
