Slewing bearing is identical to ordinary bearings, it assembly simply by rings and rollers. Even so, compare to normal bearings, slewing bearing includes a lot of dissimilarities. Normally, slewing bearing possesses huge dimensions, OD usually betwwen 0.4m to 10m, plus some even to 40m. Under normal situations, slewing bearing functioning in a low speed, high load state. Slewing bearing includes installation holes, lubricating holes and sealing unit. It has compact stucture, convenience to guide rotate, simple set up and easy repair etc.
EPT slewing ring bearings can be found in many patterns with internal, external or without gear. The reduced cross section, hefty load capability and integrated equipment make these bearings ideal structure components. Slewing ring bearings are trusted in structure machinery, mining devices and many other industrial products.
Slewing bearing is a huge of bearing with exceptional structure that could bear integrated load just like axle load, radial load and overturning load. It combines support, rotating, transmitting, fixed, sealed, anti-corrosion and different functions into one product. Widely used in lifting machinery, structure machinery, tranny machinery, mining and metallurgy machinery, medical products and radar, deliver, wind power and other industries.
Slewing Ring Bearings are precision built to manage a variety of load types which includes radial, axial, moment or perhaps a combination of every. Their unique construction and compact footprint help facilitate ease of mounting and repair. Seals are standard for retaining grease and keeping contaminants out. Re-lubricating holes are incorporated into the design, evenly distributed around the bearing, to allow for grease replenishment which helps reduce friction and use 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 instant concurrently. And they are made up of two seat rings, which design in small structure and light weight, steel ball connection with the circular raceway at four points. There will be three types of this kind of single row 4 factors get in touch with ball slewing bearing: without gear bearing (non tooth), exterior gear bearing (external tooth), and Internal equipment bearing (internal tooth).
EPT slewing band bearings may support radial, axial and tilting point in time loads acting either singly or 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, which will measurably 
decrease the overall expense and simplify the design. Slewing rings will 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 respect to the axial load and radial load coming on the Slewing bearing. It varies from 10 mm to 60 mm. The loads are calculated using software to ensure correct Shaft Clamp china selection for the slewing bearing. The material assortment is done predicated on the input parameters and the requirement of the customer. Generally, the material selected for slew ring is C45 and En19 or 42CrMO4. Excavator and crawler applications and also the boom cranes generally have the materials as 50Mn. The balls are created from High chromium steel, generally denoted by 100Cr6 and the cages are made of either nylon 6 or nylon 66 based on the load conditions.
We makes slewing ring bearings for use in a variety of demanding industries such as heavy equipment, coal and oil, medical systems, renewable energy and semiconductor production. These versatile bearings are specifically designed to handle large, hefty, slow-oscillating loads like those in cranes, booms and lifts, yet can be used in high-reliability applications such as for example CT scanners and professional positioners.
