Slewing Bearing

Slewing bearing is identical to usual bearings, it assembly simply by rings and rollers. Even so, compare to normal bearings, slewing bearing has a lot of variations. Normally, slewing bearing has huge dimensions, OD generally betwwen 0.4m to 10m, plus some even to 40m. Under normal situations, slewing bearing working in a low speed, high load condition. Slewing bearing comes with mounting holes, lubricating holes and sealing device. It has compact stucture, convenience to steer rotate, simple assembly and easy maintenance etc.

EPT slewing band bearings can be purchased in many patterns with internal, external or without gear. The reduced cross section, serious load capability and integrated equipment make these bearings suitable structure components. Slewing band bearings are trusted in engineering machinery, mining devices and many other industrial products.
Slewing bearing can be a big of bearing with special structure that may bear integrated load just like axle load, radial load and overturning load. It combines support, rotating, transmission, fixed, sealed, anti-corrosion and various other functions into one product. Widely used in lifting machinery, construction machinery, transmitting machinery, mining and metallurgy machinery, medical apparatus and radar, ship, wind power and additional industries.

Slewing Ring Bearings are precision built to manage a range of load types which includes radial, axial, moment or perhaps a combination of every. Their particular construction and small Shaft Clamp china footprint help facilitate ease of mounting and protection. Seals are typical for retaining grease and keeping contaminants out. Re-lubricating holes are incorporated into the style, evenly distributed around the bearing, to allow for grease replenishment which will help reduce friction and don 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 moment concurrently. And they are made up of two seat rings, which design in compact structure and light-weight, steel ball connection with the circular raceway at four factors. There will be three types of this sort of single row 4 things speak to ball slewing bearing: without equipment bearing (non tooth), exterior gear bearing (external tooth), and Internal equipment bearing (internal tooth).
EPT slewing band bearings can support radial, axial and tilting second loads performing either singly or perhaps in combination and in virtually any direction. Therefore, you’ll be able to replace the combination set up of radial and axial bearings by a single bearing, that may measurably reduce the overall cost and simplify the look. Slewing rings will be sealed on both sides, lubricated with high quality grease, could be relubricated via lubrication nipples and so are particularly simple to install.

The ball size is normally chosen with regards to the axial load and radial load arriving on the Slewing bearing. It varies from 10 mm to 60 mm. The loads are calculated using software to ensure correct collection for the slewing bearing. The material collection is done based on the type parameters and the requirement of the client. Generally, the material selected for slew band is certainly C45 and En19 or 42CrMO4. Excavator and crawler applications and also the boom cranes generally possess the material as 50Mn. The balls are created from High chromium metal, generally denoted by 100Cr6 and the cages are made of either nylon 6 or nylon 66 according to the load conditions.
We makes slewing ring bearings for use in a variety of demanding industries such as heavy equipment, oil and gas, medical systems, renewable strength and semiconductor developing. These versatile bearings are specifically designed to handle large, weighty, 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 industrial positioners.
