Slewing bearing is identical to normal bearings, it assembly simply by rings and rollers. On the other hand, compare to normal bearings, slewing bearing has a lot of variances. Normally, slewing bearing possesses huge dimensions, OD generally betwwen 0.4m to 10m, plus some even to 40m. Under normal circumstances, slewing bearing operating in a minimal speed, high load condition. Slewing bearing comes with mounting holes, lubricating holes and sealing unit. It has small stucture, convenience to guide rotate, simple assembly and easy protection etc.
EPT slewing band Shaft Clamp china bearings are available in many models with internal, external or without gear. The low cross section, heavy load capability and integrated gear make these bearings ideal structure components. Slewing ring bearings are trusted in building machinery, mining gear and several other industrial products.
Slewing bearing is certainly a large of bearing with distinctive structure that may bear integrated load like axle load, radial load and overturning load. It combines support, rotating, transmitting, fixed, sealed, anti-corrosion and other functions into one product. Trusted in lifting machinery, structure machinery, transmission machinery, mining and metallurgy machinery, medical gear and radar, ship, wind power and additional industries.
Slewing Ring Bearings happen to be precision created to manage a variety of load types which includes radial, axial, moment or perhaps a combination of every. Their particular construction and small footprint help facilitate ease of mounting and repair. Seals are standard 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 allows reduce friction and wear and extend bearing existence.
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 bands, 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 points get in touch with ball slewing bearing: without equipment bearing (non tooth), exterior gear bearing (external tooth), and Internal gear bearing (internal tooth).
EPT slewing ring bearings may support radial, axial and tilting moment 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, that will measurably reduce the overall expense and simplify the look. Slewing rings are 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 happen to be calculated using software to ensure correct selection for the slewing bearing. The material variety is done predicated on the suggestions parameters and the requirement of the customer. Generally, the material 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 constructed of High chromium metal, generally denoted by 100Cr6 and the cages are made from either nylon 6 or nylon 66 based on the load conditions.
We makes slewing band bearings for use in a number of 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, weighty, slow-oscillating loads like those in cranes, booms and lifts, yet may also be used in high-reliability applications such as for example CT scanners and industrial positioners.
