Slewing bearing is identical to common bearings, it assembly by rings and rollers. However, compare to normal bearings, slewing bearing includes a lot of distinctions. Normally, slewing bearing possesses huge dimensions, OD generally betwwen 0.4m to 10m, plus some even to 40m. Under normal circumstances, slewing bearing functioning in a low speed, high load condition. Slewing bearing comes with mounting holes, lubricating holes and sealing system. It has compact stucture, convenience to guide rotate, simple assembly and easy protection etc.
EPT slewing band bearings can be found in many styles with internal, external or perhaps without gear. The low cross section, hefty load capability and integrated equipment make these bearings ideally suited structure components. Slewing band bearings are trusted in construction machinery, mining devices and many other industrial products.
Slewing bearing is normally a sizable of bearing with distinctive structure that could bear integrated load just like axle load, radial load and overturning load. It combines support, rotating, transmitting, fixed, sealed, Shaft Clamp china anti-corrosion and different functions into one unit. Trusted in lifting machinery, engineering machinery, tranny machinery, mining and metallurgy machinery, medical gear and radar, deliver, wind power and additional industries.
Slewing Ring Bearings happen to be precision created to manage many different load types which includes radial, axial, moment or perhaps a combination of every. Their unique construction and small footprint help facilitate ease of mounting and maintenance. Seals are standard for retaining grease and keeping contaminants out. Re-lubricating holes are integrated into the design, evenly distributed around the bearing, to permit for grease replenishment which helps reduce friction and wear and extend bearing existence.
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 bands, which design in compact structure and light weight, steel ball contact with the circular raceway at four points. There happen to be three types of the sort of single row 4 tips speak to 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 minute loads performing either singly or perhaps in combination and in virtually any direction. Therefore, it is possible to replace the combination set up of radial and axial bearings by a single bearing, which will measurably decrease the overall expense and simplify the design. Slewing rings happen to be 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 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 happen to be calculated using software to ensure correct selection for the slewing bearing. The material variety is done based on the type parameters and the requirement of the customer. Generally, the materials selected for slew ring can be C45 and En19 or 42CrMO4. Excavator and crawler applications and also the boom cranes generally possess the materials as 50Mn. The balls are made from High chromium metal, generally denoted by 100Cr6 and the cages are made of 
either nylon 6 or nylon 66 depending on the load conditions.
We makes slewing band 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 are specifically made to handle large, large, slow-oscillating loads like those in cranes, booms and lifts, yet can also be used in high-accuracy applications such as for example CT scanners and industrial positioners.
