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 offers huge dimensions, OD generally betwwen 0.4m to 10m, plus some even to 40m. Under normal situations, slewing bearing functioning in a low speed, high load condition. Slewing bearing includes installation holes, lubricating holes and sealing product. It has compact stucture, convenience to guide rotate, simple unit installation and easy protection etc.
EPT slewing ring bearings can be purchased in many styles with internal, external or perhaps without gear. The low cross section, hefty load capacity and integrated gear make these bearings best structure components. Slewing band bearings are widely used in development machinery, mining products and several other industrial products.
Slewing bearing is certainly a huge of bearing with specialized structure that could bear integrated load like axle load, radial load and overturning load. It combines support, rotating, tranny, 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 devices and radar, ship, wind power and various other industries.
Slewing Ring Bearings are precision built to manage a range of load types which include radial, axial, moment or a combination of each. Their particular construction and small footprint help facilitate ease of mounting and maintenance. 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 will help reduce friction and have on and extend bearing life.
The Single-Row Ball type Slewing Band have four points with one row. They could bear axial load, radial load and tilting instant at the same time. And they are made up of two seat rings, which design in compact structure and light weight, steel ball contact with the circular raceway at four tips. There happen to be three types of this sort of single row 4 things get in touch with ball slewing bearing: without equipment bearing (non tooth), external gear bearing (exterior tooth), and Internal gear bearing 
(internal tooth).
EPT slewing ring bearings can support radial, axial and tilting moment loads performing either singly or in combination and in any direction. Therefore, you’ll be able to replace the combination arrangement of radial and axial bearings by an individual bearing, that will measurably decrease the overall expense and simplify the design. Slewing rings are sealed on both sides, lubricated with top quality grease, could be relubricated via lubrication nipples and so are particularly easy to install.
The ball size is normally 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 are calculated using software to ensure correct variety for the slewing bearing. The material collection is done predicated on the insight parameters and the requirement of the customer. Generally, the material selected for slew ring is normally C45 and En19 or 42CrMO4. Excavator and crawler applications plus the boom cranes generally possess the materials as 50Mn. The balls are made of High chromium metal, generally denoted by 100Cr6 and the cages are made of either nylon 6 or nylon 66 depending on the load conditions.
We makes slewing ring bearings for use in a variety of demanding industries such as for example heavy equipment, oil and gas, medical systems, renewable strength and semiconductor production. These versatile bearings are specifically designed to handle large, large, slow-oscillating loads like those in cranes, booms and lifts, yet may also be used in high-accuracy applications such as CT scanners and commercial positioners.
