Slewing Bearing

Slewing bearing is same as regular bearings, it assembly simply by rings and rollers. Even so, compare to normal bearings, slewing bearing includes a lot of variances. Normally, slewing bearing has huge dimensions, OD usually betwwen 0.4m to 10m, plus some even to 40m. Under normal circumstances, slewing bearing functioning in a minimal speed, high load condition. Slewing bearing comes with mounting holes, lubricating holes and sealing machine. It has small stucture, convenience to steer rotate, simple unit installation and easy protection etc.

EPT slewing ring bearings are available in many patterns with internal, external or without gear. The reduced cross section, hefty load capability and integrated equipment make these bearings preferred structure components. Slewing ring bearings are trusted in engineering machinery, mining gear and many other industrial products.
Slewing bearing is normally a large of bearing with exceptional structure that can bear integrated load like axle load, radial load and overturning load. It combines support, rotating, transmission, fixed, sealed, anti-corrosion and various other functions into one unit. Widely used in lifting machinery, construction machinery, tranny machinery, mining and metallurgy machinery, medical apparatus and radar, ship, wind power and different industries.

Slewing Ring Bearings will be precision created to manage various load types which include radial, axial, moment or a combination of every. Their particular construction and small footprint help facilitate simple mounting and repair. Seals are regular for retaining grease and keeping contaminants out. Re-lubricating holes are included into the style, evenly distributed around the bearing, to allow for grease replenishment which will help reduce friction and dress in 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 second simultaneously. And they are composed of two seat rings, which design in small structure and light weight, steel ball contact with the circular raceway at four details. There happen to be three types of this kind of single row 4 items get in touch with ball slewing bearing: without gear bearing (non tooth), external gear bearing (exterior tooth), and Internal gear bearing (internal tooth).
EPT slewing band bearings may support radial, axial and tilting second loads acting 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 an individual bearing, that may measurably reduce the overall cost 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 so are particularly easy to install.

The ball size is generally 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 will be calculated using software to ensure correct selection for the slewing bearing. The material selection is done based on the suggestions 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 as well as the boom cranes generally have the material as 50Mn. The balls are created from High chromium metal, generally denoted by 100Cr6 and the cages are constructed of either nylon 6 or nylon 66 based on the load conditions.
We makes slewing ring bearings for use in various demanding industries such as for example heavy equipment, coal and oil, medical systems, renewable strength and semiconductor manufacturing. These versatile bearings are specifically designed to handle large, hefty, slow-oscillating loads like those in cranes, booms and lifts, yet can be used in high-precision applications such as CT scanners and commercial positioners.
