Slewing bearing is same as typical bearings, it assembly by rings and rollers. However, compare to normal bearings, slewing bearing includes a lot of variations. Normally, slewing bearing possesses huge dimensions, OD usually betwwen 0.4m to 10m, and some even to 40m. Under normal conditions, slewing bearing operating in a minimal speed, high load condition. Slewing bearing includes installation holes, lubricating holes and sealing system. It has compact stucture, convenience to steer rotate, simple set up and easy maintenance etc.
EPT slewing band bearings can be found in many designs with internal, external or without gear. The low cross section, large load capability and integrated gear make these bearings ideal structure components. Slewing ring bearings are trusted in construction machinery, mining equipment and many other industrial products.
Slewing bearing is definitely a big of bearing with unique structure that may bear integrated load like axle load, radial load and overturning load. It combines support, rotating, transmitting, fixed, sealed, anti-corrosion and various other functions into one unit. Widely used in lifting machinery, development machinery, transmission machinery, mining and metallurgy machinery, medical gear and radar, deliver, wind power and different industries.
Slewing Ring Bearings are precision created to manage many different load types which include radial, axial, moment or perhaps a combination of every. Their unique construction and small footprint help facilitate simple mounting and protection. Seals are standard for retaining grease and keeping contaminants out. Re-lubricating holes are included into the design, evenly distributed around the bearing, to permit for grease replenishment which assists reduce friction and put 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 minute as well. And they are composed of two seat rings, which design in compact structure and light-weight, steel ball connection with the circular raceway at four factors. There are three types of the kind of single row 4 details get in touch with ball slewing bearing: without gear bearing (non tooth), exterior gear bearing (external tooth), and Internal gear bearing (internal tooth).
EPT slewing ring bearings can support radial, axial and tilting minute loads performing either singly or perhaps in combination and in any direction. Therefore, you’ll be able to replace the combination set up of radial and axial bearings by a single bearing, which will measurably reduce the overall expense and simplify the design. Slewing rings happen to be sealed on both sides, lubricated with top quality grease, can be relubricated via lubrication nipples and so are particularly easy 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 are calculated using software to make sure correct variety for the slewing bearing. The material collection is done based on the insight parameters and the necessity of the customer. Generally, the material selected for slew band is usually C45 and En19 or 42CrMO4. Excavator and crawler applications in addition to the boom cranes generally have the materials as 50Mn. The balls are made of High chromium metal, generally denoted by 100Cr6 and the cages are constructed of either nylon 6 or nylon 66 according to the load conditions.
We makes slewing ring bearings for use in various demanding industries such as heavy equipment, coal and oil, medical systems, renewable energy and semiconductor manufacturing. These versatile bearings are specifically designed to handle large, serious, slow-oscillating loads like those in cranes, booms and lifts, yet can even be used in high-accuracy applications such as CT scanners and industrial positioners.
