Slewing Bearing

Slewing bearing is same as typical bearings, it assembly simply by rings and rollers. Even so, compare to normal bearings, slewing bearing includes a lot of differences. Normally, slewing bearing features huge dimensions, OD usually betwwen 0.4m to 10m, plus some even to 40m. Under normal instances, slewing bearing operating in a low speed, high load condition. Slewing bearing includes installation 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 purchased in many patterns with internal, external or perhaps without gear. The low cross section, weighty load capability and integrated equipment make these bearings preferred structure components. Slewing ring bearings are widely used in building machinery, mining devices and many other industrial products.
Slewing bearing is definitely a sizable of bearing with unique structure that could bear integrated load just like axle load, radial load and overturning load. It combines support, rotating, tranny, fixed, sealed, anti-corrosion and various other functions into one product. Trusted in lifting machinery, development machinery, tranny machinery, mining and metallurgy machinery, medical gear and radar, ship, wind power and other industries.

Slewing Ring Bearings are precision created to manage a number of load types including radial, axial, moment or perhaps a combination of every. Their unique construction and small footprint help facilitate simple mounting and maintenance. Seals are regular for retaining grease and keeping contaminants out. Re-lubricating holes are included into the style, evenly distributed around the bearing, to permit for grease replenishment which allows reduce friction and dress in and extend bearing existence.
The Single-Row Ball type Slewing Ring have four points with one row. They could bear axial load, radial load and tilting point in time concurrently. And they are made up of two seat bands, which design in small structure and light weight, steel ball connection with the circular raceway at four tips. There happen to be three types of this kind of single row 4 items speak to 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 second loads acting either singly or in combination and in virtually any direction. Therefore, you’ll be able to replace the combination arrangement of radial and axial bearings by a single bearing, that will measurably reduce the overall price and simplify the look. Slewing rings will be sealed on both sides, lubricated with high quality grease, can be relubricated via lubrication nipples and are particularly easy to install.

The ball size is generally chosen with respect to the axial load and radial load arriving 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 variety is done predicated on the source parameters and the requirement of the client. Generally, the material selected for slew band is definitely C45 and En19 or 42CrMO4. Excavator and crawler applications as well as the boom cranes generally possess the materials as 50Mn. The balls are made from High chromium metal, generally denoted by 100Cr6 and the cages are constructed of either nylon 6 or nylon 66 depending on the load conditions.
We makes slewing ring bearings for use in various demanding industries such as heavy equipment, coal and oil, medical systems, renewable strength and semiconductor manufacturing. These versatile bearings are specifically designed to handle large, major, slow-oscillating loads like those in cranes, booms and lifts, yet may also be used in high-reliability applications such as CT scanners and professional positioners.
