Slewing Bearing

Slewing bearing is same as usual bearings, it assembly by rings and rollers. On the other hand, compare to normal bearings, slewing bearing includes a lot of differences. Normally, slewing bearing offers huge dimensions, OD generally betwwen 0.4m to 10m, plus some even to 40m. Under normal situations, slewing bearing operating in a low 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 maintenance etc.

EPT slewing ring bearings can be purchased in many patterns with internal, external or without gear. The low cross section, hefty load ability and integrated equipment make these bearings ideally suited structure components. Slewing ring bearings are trusted in construction machinery, mining products and several other industrial products.
Slewing bearing can be a big of bearing with special structure that could bear integrated load like axle load, radial load and overturning load. It combines support, rotating, transmission, fixed, sealed, anti-corrosion and additional functions into one unit. Trusted in lifting machinery, construction machinery, tranny machinery, mining and metallurgy machinery, medical apparatus and radar, deliver, wind power and other industries.

Slewing Ring Bearings are precision created to manage a range of load types including radial, axial, moment or perhaps a combination of every. Their unique construction and compact footprint help facilitate simple mounting and maintenance. Seals are typical for retaining grease and keeping contaminants out. Re-lubricating holes are integrated into the design, evenly distributed around the bearing, to permit for grease replenishment which allows reduce friction and wear and extend bearing lifestyle.
The Single-Row Ball type Slewing Ring have four points with one row. They could bear axial load, radial load and tilting minute as well. And they are composed of two seat bands, which design in compact structure and light-weight, steel ball contact with the circular raceway at four factors. There will be three types of this sort of single row 4 details contact ball slewing bearing: without equipment bearing (non tooth), Shaft Clamp china 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 performing either singly or in combination and in any direction. Therefore, it is possible to replace the combination arrangement of radial and axial bearings by an individual bearing, that will measurably decrease the overall cost and simplify the design. Slewing rings are sealed on both sides, lubricated with high quality grease, can be relubricated via lubrication nipples and so 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 happen to be calculated using software to ensure correct selection for the slewing bearing. The material assortment is done based on the suggestions parameters and the necessity of the client. Generally, the material selected for slew ring is C45 and En19 or 42CrMO4. Excavator and crawler applications and also the boom cranes generally have the material as 50Mn. The balls are constructed with High chromium steel, generally denoted by 100Cr6 and the cages are made of either nylon 6 or nylon 66 depending on the load conditions.
We makes slewing band bearings for use in various demanding industries such as heavy equipment, oil and gas, medical systems, renewable strength and semiconductor manufacturing. These versatile bearings will be specifically designed to handle large, serious, slow-oscillating loads like those in cranes, booms and lifts, yet can also be used in high-precision applications such as CT scanners and industrial positioners.
