Slewing Bearing

Slewing bearing is same as regular bearings, it assembly simply by rings and rollers. However, compare to normal bearings, slewing bearing has a lot of variations. Normally, slewing bearing offers 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 installation holes, lubricating holes and sealing system. It has compact stucture, convenience to guide rotate, simple unit installation and easy maintenance etc.

EPT slewing ring bearings are available in many styles with internal, external or without gear. The low cross section, major load capacity and integrated equipment make these bearings best structure components. Slewing band bearings are widely used in building machinery, mining products and many other industrial products.
Slewing bearing is certainly a large of bearing with distinctive 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 device. Widely used in lifting machinery, structure machinery, transmitting machinery, mining and metallurgy machinery, medical products and radar, ship, wind power and other industries.

Slewing Ring Bearings are precision created to manage a range of load types including radial, axial, moment or a combination of each. Their particular construction and compact footprint help facilitate ease of mounting and protection. Seals are standard for retaining grease and keeping contaminants out. Re-lubricating holes are integrated into the style, evenly distributed around the bearing, to permit for grease replenishment which can 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 minute as well. And they are made up of two seat bands, which design in compact structure and light-weight, steel ball contact with the circular raceway at four details. There happen to be three types of the sort of single row 4 points get in touch with ball slewing bearing: without gear bearing (non tooth), external gear bearing (external tooth), and Internal gear bearing (internal tooth).
EPT slewing band bearings can support radial, axial and tilting minute loads performing either singly or perhaps in combination and in any direction. Therefore, it is possible to replace the combination arrangement of radial and axial bearings by a single bearing, that will measurably decrease the overall expense and simplify the look. Slewing rings are sealed on both sides, lubricated with high quality grease, could be relubricated via lubrication nipples and are particularly easy 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 are calculated using software to make sure correct variety for the slewing bearing. The material selection is done predicated on the suggestions parameters and the requirement of the client. Generally, the material selected for slew band is normally C45 and En19 or 42CrMO4. Excavator and crawler applications and also the boom cranes generally possess the material as 50Mn. The balls are made of High chromium steel, generally denoted by 100Cr6 and the cages are made from either nylon 6 or nylon 66 according to the load conditions.
We makes slewing ring bearings for use in various demanding industries such as heavy equipment, oil and gas, medical systems, renewable strength 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 be used in high-accuracy applications such as for example CT scanners and commercial positioners.
