Slewing bearing is same as ordinary bearings, it assembly simply by rings and rollers. Nevertheless, compare to normal bearings, slewing bearing has a lot of dissimilarities. Normally, slewing bearing features huge dimensions, OD usually betwwen 0.4m to 10m, and some even to 40m. Under normal instances, slewing bearing operating in a low speed, high load state. Slewing bearing comes with installation holes, lubricating holes and sealing device. It has compact stucture, convenience to guide rotate, simple installation and easy protection etc.

EPT slewing ring bearings can be purchased in many designs with internal, external or without gear. The low cross Shaft Clamp china section, large load potential and integrated gear make these bearings best structure components. Slewing ring bearings are widely used in engineering machinery, mining devices and many other industrial products.
Slewing bearing is definitely a large of bearing with special 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 other functions into one product. Trusted in lifting machinery, engineering machinery, transmission machinery, mining and metallurgy machinery, medical devices and radar, deliver, wind power and other industries.

Slewing Ring Bearings happen to be precision built to manage various load types which includes radial, axial, moment or a combination of every. Their particular construction and compact footprint help facilitate simple mounting and protection. Seals are standard 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 don 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 minute at the same time. And they are made up of two seat rings, which design in small structure and light-weight, steel ball contact with the circular raceway at four tips. There happen to be three types of the kind of single row 4 points get in touch with ball slewing bearing: without gear bearing (non tooth), external gear bearing (exterior tooth), and Internal gear bearing (internal tooth).
EPT slewing band bearings can 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 set up of radial and axial bearings by a single bearing, that may measurably reduce the overall price and simplify the look. Slewing rings happen to be sealed on both sides, lubricated with top quality grease, can be relubricated via lubrication nipples and are particularly easy to install.

The ball size is normally chosen with respect to the axial load and radial load approaching on the Slewing bearing. It varies from 10 mm to 60 mm. The loads will be calculated using software to make sure correct assortment for the slewing bearing. The material collection is done predicated on the source parameters and the necessity of the customer. Generally, the materials selected for slew ring is normally 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 steel, generally denoted by 100Cr6 and the cages are made of either nylon 6 or nylon 66 according to the load conditions.
We makes slewing ring bearings for use in a number of demanding industries such as heavy equipment, oil and gas, medical systems, renewable strength and semiconductor developing. These versatile bearings are specifically designed 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 for example CT scanners and professional positioners.
