Slewing Bearing

Slewing bearing is same as usual bearings, it assembly simply by rings and rollers. Nevertheless, compare on track bearings, slewing bearing has a lot of differences. Normally, slewing bearing provides huge dimensions, OD usually betwwen 0.4m to 10m, plus some even to 40m. Under normal circumstances, slewing bearing working in a minimal speed, high load condition. Slewing bearing includes mounting holes, lubricating holes and sealing gadget. It has compact stucture, convenience to guide rotate, simple unit installation and easy maintenance etc.

EPT slewing ring bearings can be found in many models with internal, external or without gear. The reduced cross section, weighty load ability and integrated equipment make these bearings best structure components. Slewing band bearings are trusted in engineering machinery, mining gear and many other industrial products.
Slewing bearing can be a large of bearing with particular structure that can bear integrated load like axle load, radial load and overturning load. It combines support, rotating, transmitting, fixed, sealed, anti-corrosion and other functions into one unit. Widely used in lifting machinery, structure machinery, transmitting machinery, mining and metallurgy machinery, medical equipment and radar, deliver, wind power and additional industries.

Slewing Ring Bearings are precision created to manage a variety of load types which include radial, axial, moment or a combination of every. Their particular construction and small footprint help facilitate ease of mounting and protection. Seals are normal 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 facilitates reduce friction and use and extend bearing your life.
The Single-Row Ball type Slewing Band have four points with one row. They could bear axial load, radial load and tilting instant at the same time. And they are made up of two seat rings, which design in compact structure and light-weight, steel ball contact with the circular raceway at four details. There are three types of this sort of single row 4 items contact ball slewing bearing: without equipment bearing (non tooth), exterior gear bearing (external tooth), and Internal equipment bearing (internal tooth).
EPT slewing ring bearings may support radial, axial and tilting point in time loads acting either singly or 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, that may measurably reduce the overall price and simplify the look. Slewing rings will 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 normally 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 happen to be calculated using software to ensure correct variety for the slewing bearing. The material selection is done based on the source parameters and the necessity of the customer. Generally, the material selected for slew ring is usually C45 and En19 or 42CrMO4. Excavator and crawler applications along with the boom cranes generally have the material as 50Mn. The balls are constructed of High chromium steel, generally denoted by 100Cr6 and the cages are created from 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 energy and semiconductor developing. These versatile bearings happen to be specifically made to handle large, large, slow-oscillating loads like those in cranes, booms and lifts, yet can also be used in high-accuracy applications such as for example CT scanners and industrial positioners.
