Slewing Bearing

Slewing bearing is identical to regular bearings, it assembly by rings and rollers. Even so, compare on track bearings, slewing bearing includes a lot of distinctions. Normally, slewing bearing features huge dimensions, OD generally betwwen 0.4m to 10m, and some even to 40m. Under normal situations, slewing bearing operating in a low speed, high load condition. Slewing bearing comes with mounting holes, lubricating holes and sealing product. It has compact stucture, convenience to guide rotate, simple set up and easy repair etc.

EPT slewing band bearings are available in many designs with internal, external or perhaps without gear. The low cross section, hefty load capability and integrated gear make these bearings preferred structure components. Slewing ring bearings are trusted in structure machinery, mining devices and several other industrial products.
Slewing bearing is usually a huge of bearing with special structure that may bear integrated load just like axle load, radial load and overturning load. It combines support, rotating, transmission, fixed, sealed, anti-corrosion and additional functions into one product. Widely used in lifting machinery, engineering machinery, transmission machinery, mining and metallurgy machinery, medical tools and radar, ship, wind power and different industries.

Slewing Ring Bearings will be precision created to manage various load types which includes radial, axial, moment or perhaps a combination of each. Their unique construction and compact footprint help facilitate ease of mounting and maintenance. 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 will help 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 point in time simultaneously. And they are made up of two seat bands, which design in compact structure and light-weight, steel ball connection with the circular raceway at four things. There will be three types of the kind of single row 4 factors speak to ball slewing bearing: without equipment bearing (non tooth), external gear bearing (exterior tooth), and Internal gear bearing (internal tooth).
EPT slewing band bearings can support radial, axial and tilting second loads performing 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 an individual bearing, which will measurably decrease the overall expense and simplify the design. Slewing rings happen to be sealed on both sides, lubricated with high quality grease, could be relubricated via lubrication nipples and so are particularly simple 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 will be calculated using software to ensure correct selection for the slewing bearing. The material variety is done predicated on the input parameters and the requirement of the customer. Generally, the materials selected for slew band can be C45 and En19 or 42CrMO4. Excavator and crawler applications plus the boom cranes generally possess the material as 50Mn. The balls are constructed with High chromium metal, generally denoted by 100Cr6 and the cages are made of either nylon 6 or nylon 66 based on the load conditions.
We makes slewing band bearings for use in a range of demanding industries such as for example heavy equipment, coal and oil, medical systems, renewable strength and semiconductor manufacturing. These versatile bearings will be specifically designed to handle large, heavy, slow-oscillating loads like those in cranes, booms and lifts, yet can even be used in high-precision applications such as for example CT scanners and professional positioners.
