Slewing bearing is same as ordinary bearings, it assembly simply by rings and rollers. However, compare on track bearings, slewing bearing includes a lot of differences. Normally, slewing bearing has huge dimensions, OD usually Shaft Clamp china betwwen 0.4m to 10m, and some even to 40m. Under normal situations, slewing bearing operating in a low speed, high load condition. Slewing bearing comes with mounting holes, lubricating holes and sealing machine. It has compact stucture, convenience to steer rotate, simple assembly and easy maintenance etc.
EPT slewing ring bearings can be found in many patterns with internal, external or without gear. The reduced cross section, hefty load potential and integrated equipment make these bearings best structure components. Slewing band bearings are widely used in construction machinery, mining apparatus and many other industrial products.
Slewing bearing can be a sizable of bearing with unique structure that may bear integrated load like axle load, radial load and overturning load. It combines support, rotating, tranny, fixed, sealed, anti-corrosion and various other functions into one unit. Widely used in lifting machinery, development machinery, transmission machinery, mining and metallurgy machinery, medical gear and radar, ship, wind power and other industries.
Slewing Ring Bearings will be precision created to manage a variety of load types which includes radial, axial, moment or a combination of every. Their particular construction and small 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 permit for grease replenishment which will help reduce friction and wear 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 point in time as well. 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 tips. There are three types of the kind of single row 4 things contact ball slewing bearing: without equipment bearing (non tooth), external gear bearing (exterior tooth), and Internal equipment bearing (internal tooth).
EPT slewing band 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 arrangement of radial and axial bearings by a single bearing, that may measurably decrease the overall cost 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 easy to install.
The ball size is normally chosen with regards to the axial load and radial load coming on the Slewing bearing. It varies from 10 mm to 60 mm. The loads are calculated using software to ensure correct variety for the slewing bearing. The material variety is done predicated on the suggestions parameters and the necessity of the customer. Generally, the material selected for slew band is normally C45 and En19 or 42CrMO4. Excavator and crawler applications and also the boom cranes generally have the materials as 50Mn. The balls are constructed with High chromium metal, generally denoted by 100Cr6 and the cages are constructed with either nylon 6 or nylon 66 according to the load conditions.
We makes slewing ring bearings for use in a variety 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, serious, slow-oscillating loads like those in cranes, booms and lifts, yet can even be used in high-precision applications such as for example CT scanners and commercial positioners.
