Slewing bearing is identical to normal bearings, it assembly by rings and rollers. However, compare to normal bearings, slewing bearing has a lot of variances. Normally, slewing bearing possesses huge dimensions, OD usually betwwen 0.4m to 10m, and some even to 40m. Under normal instances, slewing bearing functioning in a low speed, high load condition. Slewing bearing comes with installation holes, lubricating holes and sealing system. It has small stucture, convenience to steer rotate, simple set up and easy maintenance etc.

EPT slewing band bearings can be found in many models with internal, external or without gear. The low cross section, major load ability and integrated equipment make these bearings great structure components. Slewing ring bearings are trusted in building machinery, mining gear and many other industrial products.
Slewing bearing is normally a big of bearing with special structure that can bear integrated load just like axle load, radial load and overturning load. It combines support, rotating, tranny, fixed, sealed, anti-corrosion and additional functions into one product. Widely used in lifting machinery, construction machinery, transmitting machinery, mining and metallurgy machinery, medical tools and radar, ship, wind power and different industries.

Slewing Ring Bearings are precision created to manage many different load types which include radial, axial, moment or a combination of each. Their unique construction and compact footprint help facilitate ease of mounting and maintenance. Seals are normal for retaining grease and keeping contaminants out. Re-lubricating holes are integrated into the design, evenly distributed around the bearing, to allow for grease replenishment which will help reduce friction and have on and extend bearing life.
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 at the same time. 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 tips. There are three types of this kind of single row 4 things contact ball slewing bearing: without gear bearing (non tooth), exterior gear bearing (external tooth), and Internal gear bearing (internal tooth).
EPT slewing band bearings may support radial, axial and tilting minute loads performing either singly or perhaps in combination and in virtually any direction. Therefore, it is possible to replace the combination arrangement of radial and axial bearings by a single bearing, which will measurably reduce the overall cost and simplify the look. Slewing rings happen to be sealed on both sides, lubricated with top quality grease, could be relubricated via lubrication nipples and are particularly easy to install.

The ball size is normally chosen with respect 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 collection for the slewing bearing. The material collection is done based on the insight parameters and the necessity of the customer. Generally, the materials selected for slew band is C45 and En19 or 42CrMO4. Excavator and crawler applications and also the boom cranes generally have the material as 50Mn. The balls are created from High chromium metal, generally denoted by 100Cr6 and the cages are created from either nylon 6 or nylon 66 according to the load conditions.
We makes slewing ring bearings for use in a range of demanding industries such as heavy equipment, coal and oil, medical systems, renewable energy and semiconductor manufacturing. These versatile bearings will be Shaft Clamp china specifically designed to handle large, hefty, slow-oscillating loads like those in cranes, booms and lifts, yet may also be used in high-accuracy applications such as for example CT scanners and professional positioners.
