Slewing Bearing

Slewing bearing is same as normal bearings, it assembly simply by rings and rollers. Nevertheless, compare to normal bearings, slewing bearing includes a lot of differences. Normally, slewing bearing provides huge dimensions, OD generally betwwen 0.4m to 10m, plus some even to 40m. Under normal instances, slewing bearing functioning in a low speed, high load state. Slewing bearing includes installation holes, lubricating holes and sealing device. It has small stucture, convenience to guide rotate, simple assembly and easy maintenance etc.

EPT slewing band bearings are available in many patterns with internal, external or perhaps without gear. The low cross section, major load capacity and integrated gear make these bearings suitable structure components. Slewing ring bearings are trusted in building machinery, mining devices and several other industrial products.
Slewing bearing is definitely a huge of bearing with special structure that could 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 unit. Widely used in Shaft Clamp china lifting machinery, development machinery, tranny machinery, mining and metallurgy machinery, medical gear and radar, deliver, wind power and different industries.

Slewing Ring Bearings happen to be precision built to manage a number of load types which includes radial, axial, moment or a combination of each. Their unique construction and small footprint help facilitate simple mounting and protection. Seals are normal for retaining grease and keeping contaminants out. Re-lubricating holes are incorporated into the design, evenly distributed around the bearing, to allow for grease replenishment which facilitates reduce friction and have on and extend bearing lifestyle.
The Single-Row Ball type Slewing Ring have four points with one row. They could bear axial load, radial load and tilting second concurrently. And they are made up of two seat bands, which design in small structure and light-weight, steel ball contact with the circular raceway at four factors. There happen to be 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 gear bearing (internal tooth).
EPT slewing band bearings may support radial, axial and tilting minute loads performing either singly or perhaps in combination and in any direction. Therefore, you’ll be able to replace the combination arrangement of radial and axial bearings by a single bearing, which will measurably reduce the overall price 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 simple to install.

The ball size is generally 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 are calculated using software to make sure correct collection for the slewing bearing. The material variety is done based on the input parameters and the requirement of the customer. Generally, the material selected for slew band is normally C45 and En19 or 42CrMO4. Excavator and crawler applications as well as the boom cranes generally have the materials as 50Mn. The balls are constructed of High chromium steel, 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 many different demanding industries such as heavy equipment, coal and oil, medical systems, renewable strength and semiconductor manufacturing. These versatile bearings happen to be specifically designed to handle large, weighty, slow-oscillating loads like those in cranes, booms and lifts, yet can also be used in high-accuracy applications such as CT scanners and industrial positioners.
