Slewing bearing is identical to ordinary bearings, it assembly simply by rings and rollers. However, compare to normal bearings, slewing bearing has a lot of variances. Normally, slewing bearing features huge dimensions, OD generally betwwen 0.4m to 10m, and some even to 40m. Under normal situations, slewing bearing functioning in a minimal speed, high load condition. Slewing bearing includes installation holes, lubricating holes and sealing unit. It has compact stucture, convenience to steer rotate, simple set up and easy maintenance etc.

EPT slewing band bearings are available in many styles with internal, external or without gear. The reduced cross section, serious load potential and integrated equipment make these bearings best structure components. Slewing ring bearings are widely used in construction machinery, mining devices and several other industrial products.
Slewing bearing is a huge of bearing with distinctive 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 different functions into one device. Widely used in lifting machinery, engineering machinery, transmission machinery, mining and metallurgy machinery, medical gear and radar, deliver, wind power and other industries.

Slewing Ring Bearings happen to be precision built to manage various load types including radial, axial, moment or perhaps a combination of each. Their unique construction and compact footprint help facilitate ease of mounting and repair. Seals are typical 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 can help reduce friction and have on and extend bearing life.
The Single-Row Ball type Slewing Ring have four points with one row. They could bear axial load, radial load and tilting point in time at the same time. And they are composed of two seat bands, which design in compact structure and light-weight, steel ball connection with the circular raceway at four tips. There happen to be three types of the sort of single row 4 things speak to ball slewing bearing: without gear bearing (non tooth), exterior gear bearing (exterior tooth), and Internal gear bearing (internal tooth).
EPT slewing band bearings may 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 set up of radial and axial bearings by an individual bearing, which will measurably decrease the overall expense and simplify the design. Slewing rings are sealed on both sides, lubricated with top quality grease, could be relubricated via lubrication nipples and so are particularly simple to install.

The ball size is normally 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 happen to be calculated using software to ensure correct collection for the slewing bearing. The material assortment is done predicated on the source parameters and the necessity of the client. Generally, the materials selected for slew band is certainly C45 and En19 or 42CrMO4. Excavator and crawler applications along with the boom cranes generally possess the material as 50Mn. The balls are made from High chromium steel, generally denoted by 100Cr6 and the cages are constructed with either nylon 6 or nylon 66 according to the load conditions.
We makes slewing band bearings for use in a variety of demanding industries such as heavy equipment, oil and gas, medical systems, renewable strength and semiconductor production. These versatile bearings are specifically designed 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 for example CT scanners and commercial positioners.
