Slewing bearing is same as normal bearings, it assembly by rings and rollers. However, compare to normal bearings, slewing bearing has a lot of dissimilarities. Normally, slewing bearing possesses huge dimensions, OD usually betwwen 0.4m to 10m, plus some even to 40m. Under normal instances, slewing bearing functioning in a low speed, high load condition. Slewing bearing comes with mounting holes, lubricating holes and sealing unit. It has small stucture, convenience to steer rotate, simple set up and easy maintenance etc.

EPT slewing ring bearings can be found in many patterns with internal, external or without gear. The low cross section, heavy load ability and integrated equipment make these bearings great structure components. Slewing band bearings are trusted in building machinery, mining tools and several other industrial products.
Slewing bearing is normally a big of bearing with particular structure that may bear integrated load just like axle load, radial load and overturning load. It combines support, rotating, tranny, fixed, sealed, anti-corrosion and additional functions into one product. Trusted in lifting machinery, construction machinery, transmission machinery, mining and metallurgy machinery, medical devices and radar, ship, wind power and different industries.

Slewing Ring Bearings are precision built to manage various load types which include radial, axial, moment or a combination of every. Their unique construction and small footprint help facilitate ease of mounting and repair. Seals are normal for retaining grease and keeping contaminants out. Re-lubricating holes are integrated into the design, evenly distributed around the bearing, to allow for grease replenishment which will help reduce friction and have on and extend bearing life.
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 at the same time. And they are made up of two seat rings, 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), exterior gear bearing (external tooth), and Internal gear bearing (internal tooth).
EPT slewing ring bearings may 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 arrangement of radial and axial bearings by a single bearing, which will measurably decrease the overall cost and simplify the look. Slewing rings happen to be sealed on both sides, lubricated with top quality grease, could be relubricated via lubrication nipples and are particularly simple to install.

The ball size is generally chosen with regards to the axial load and radial load approaching on the Slewing bearing. It varies from 10 mm to 60 mm. The loads will be calculated using software to make sure correct variety for the slewing bearing. The material variety is done predicated on the input parameters and the necessity of the client. Generally, the material selected for slew ring is certainly C45 and En19 or 42CrMO4. Excavator and crawler applications as well as the boom cranes generally have the materials as 50Mn. The balls are made from High chromium metal, generally denoted by 100Cr6 and the cages are made from either nylon 6 or nylon 66 based on the load conditions.
We makes slewing band bearings for use in various demanding industries such as for example heavy equipment, coal and oil, medical systems, renewable strength and semiconductor making. These versatile bearings are specifically made to handle large, weighty, slow-oscillating loads like those in cranes, booms and lifts, yet may also be used in high-accuracy applications such as CT scanners and commercial positioners.
