Slewing bearing is same as usual bearings, it assembly by rings and rollers. Nevertheless, compare on track bearings, slewing bearing includes a lot of differences. Normally, slewing bearing offers huge dimensions, OD usually betwwen 0.4m to 10m, plus some even to 40m. Under normal conditions, slewing bearing functioning in a minimal speed, high load condition. Slewing bearing includes mounting holes, lubricating holes and sealing device. It has compact stucture, convenience to steer rotate, simple installation and easy repair etc.
EPT slewing ring bearings can be found in many styles with internal, external or without gear. The reduced cross section, major load capacity and integrated equipment make these bearings preferred structure components. Slewing ring bearings are widely used in development machinery, mining equipment and many other industrial products.
Slewing bearing can be a large of bearing with unique 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 different functions into one device. Trusted in lifting machinery, building machinery, transmitting machinery, mining and metallurgy machinery, medical Shaft Clamp china apparatus and radar, deliver, wind power and other industries.
Slewing Ring Bearings happen to be precision built to manage a number of load types which includes radial, axial, moment or perhaps a combination of every. Their unique construction and compact footprint help facilitate simple mounting and repair. Seals are regular for retaining grease and keeping contaminants out. Re-lubricating holes are integrated into the style, evenly distributed around the bearing, to permit for grease replenishment which can help 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 instant simultaneously. And they are composed of two seat rings, which design in compact structure and light-weight, steel ball contact with the circular raceway at four points. There will be three types of this kind of single row 4 points get in touch with ball slewing bearing: without gear bearing (non tooth), exterior gear bearing (exterior tooth), and Internal gear bearing (internal tooth).
EPT slewing ring bearings may support radial, axial and tilting instant loads acting either singly or 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 decrease the overall expense and simplify the look. Slewing rings will be 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 make sure correct variety for the slewing bearing. The material selection is done predicated on the source parameters and the requirement of the client. Generally, the material selected for slew band can be C45 and En19 or 42CrMO4. Excavator and crawler applications in addition to the boom cranes generally have the material as 50Mn. The balls are created from High chromium steel, generally denoted by 100Cr6 and the cages are constructed of either nylon 6 or nylon 66 depending on the load conditions.
We makes slewing band bearings for use in a range of demanding industries such as heavy equipment, oil and gas, medical systems, renewable energy and semiconductor making. These versatile bearings happen to be specifically made to handle large, serious, slow-oscillating loads like those in cranes, booms and lifts, yet can even be used in high-precision applications such as CT scanners and commercial positioners.
