Slewing Bearing

Slewing bearing is same as regular bearings, it assembly by rings and rollers. However, compare to normal bearings, slewing bearing has a lot of dissimilarities. 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 minimal speed, high load condition. Slewing bearing includes installation holes, lubricating holes and sealing machine. It has compact stucture, convenience to steer rotate, simple unit installation and easy protection etc.

EPT slewing ring bearings can be purchased in many designs with internal, external or perhaps without gear. The low cross section, hefty load capacity and integrated gear make these bearings ideal structure components. Slewing ring bearings are widely used in engineering machinery, mining gear and several other industrial products.
Slewing bearing can be a huge of bearing with distinctive structure that could bear integrated load like axle load, radial load and overturning load. It combines support, rotating, transmitting, fixed, sealed, anti-corrosion and various other functions into one product. Widely used in lifting machinery, construction machinery, tranny machinery, mining and metallurgy machinery, medical devices and radar, ship, wind power and various other industries.

Slewing Ring Bearings are precision built to manage various load types which include radial, axial, moment or a combination of every. Their particular construction and small footprint help facilitate ease of mounting and maintenance. Seals are regular for retaining grease and keeping contaminants out. Re-lubricating holes are incorporated into the style, evenly distributed around the bearing, to permit for grease replenishment which can help reduce friction and use 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 second at the same time. 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 things. There happen to be three types of this kind of single row 4 things contact 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 instant loads acting either singly or perhaps 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 may measurably decrease the overall expense and simplify the design. 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 ensure correct variety for the slewing bearing. The material variety is done predicated on the input 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 in addition to 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 depending on the load conditions.
We makes slewing ring bearings for use in a range of demanding industries such as heavy equipment, coal and oil, medical systems, renewable strength and semiconductor developing. These versatile bearings are specifically made to handle large, large, slow-oscillating loads like those in cranes, booms and lifts, yet can also be used in high-reliability applications such as CT scanners and commercial positioners.
