Slewing bearing is same as Shaft Clamp china regular bearings, it assembly by rings and rollers. Nevertheless, compare to normal bearings, slewing bearing includes a lot of differences. Normally, slewing bearing features huge dimensions, OD generally betwwen 0.4m to 10m, plus some even to 40m. Under normal circumstances, slewing bearing operating in a low speed, high load condition. Slewing bearing includes installation holes, lubricating holes and sealing product. It has compact stucture, convenience to guide rotate, simple installation and easy repair etc.
EPT slewing band bearings can be purchased in many patterns with internal, external or perhaps without gear. The low cross section, large load capability and integrated gear make these bearings great structure components. Slewing band bearings are widely used in building machinery, mining apparatus and many other industrial products.
Slewing bearing is a big of bearing with particular structure that can bear integrated load like axle load, radial load and overturning load. It combines support, rotating, transmitting, fixed, sealed, anti-corrosion and other functions into one product. Trusted in lifting machinery, building machinery, tranny machinery, mining and metallurgy machinery, medical devices and radar, ship, wind power and additional industries.
Slewing Ring Bearings are precision built to manage various load types including radial, axial, moment or perhaps a combination of each. Their particular construction and compact footprint help facilitate simple mounting and maintenance. Seals are regular 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 will help reduce friction and put 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 as well. 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 factors. There are three types of the sort of single row 4 factors get in touch with ball slewing bearing: without equipment bearing (non tooth), exterior gear bearing (exterior tooth), and Internal gear bearing (internal tooth).
EPT slewing ring bearings can support radial, axial and tilting instant loads acting either singly or 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, which will measurably reduce the overall cost and simplify the design. Slewing rings are sealed on both sides, lubricated with top quality grease, can be relubricated via lubrication nipples and so are particularly simple to install.
The ball size is generally 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 variety for the slewing bearing. The material variety is done based on the insight parameters and the requirement of the customer. Generally, the materials selected for slew band is C45 and En19 or 42CrMO4. Excavator and crawler applications plus the boom cranes generally possess the materials as 50Mn. The balls are made 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 ring bearings for use in a number of demanding industries such as for example heavy equipment, coal and oil, medical systems, renewable strength and semiconductor developing. These versatile bearings happen to be specifically made to handle large, major, slow-oscillating loads like those in cranes, booms and lifts, yet can also be used in high-precision applications such as CT scanners and professional positioners.
