Slewing bearing is same as regular bearings, it assembly simply by rings and rollers. However, compare on track bearings, slewing bearing includes a lot of differences. Normally, slewing bearing offers huge dimensions, OD generally betwwen 0.4m to 10m, and some even to 40m. Under normal conditions, slewing bearing operating in a minimal speed, high load state. Slewing bearing comes with installation holes, lubricating holes and sealing device. It has small stucture, convenience to guide rotate, simple assembly and easy repair etc.

EPT slewing band bearings can be purchased in many designs with internal, external or perhaps without gear. The reduced cross section, heavy load capability and integrated equipment make these bearings preferred structure components. Slewing band bearings are trusted in building machinery, mining products and several other industrial products.
Slewing bearing is a huge of bearing with special structure that can bear integrated load just like axle load, radial load and overturning load. It combines support, rotating, transmission, fixed, sealed, anti-corrosion and different functions into one product. Trusted in lifting machinery, construction machinery, transmission machinery, mining and metallurgy machinery, medical tools and radar, ship, wind power and additional industries.

Slewing Ring Bearings will be precision created to manage a variety of load types which include radial, axial, moment or a combination of every. Their unique construction and compact footprint help facilitate simple mounting and protection. Seals are normal for retaining grease and keeping contaminants out. Re-lubricating holes are incorporated into the design, evenly distributed around the bearing, to allow for grease replenishment which helps reduce friction and put on and extend bearing your life.
The Single-Row Ball type Slewing Band have four points with one row. They could bear axial load, radial load and tilting point in time concurrently. And they are composed of two seat bands, 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 sort of single row 4 details contact ball slewing bearing: without gear bearing (non tooth), external gear bearing (external tooth), and Internal gear bearing (internal tooth).
EPT slewing ring bearings may support radial, axial and tilting instant loads acting either singly or perhaps in combination and in virtually any direction. Therefore, it is possible to replace the combination set up of radial and axial bearings by an individual bearing, which will measurably decrease the overall cost and simplify the look. Slewing rings happen to be sealed on both sides, lubricated with high quality grease, can be relubricated via lubrication nipples and are particularly easy to install.

The ball size is generally 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 happen to be calculated using software to ensure correct variety for the slewing bearing. The material assortment is done predicated on the type parameters and the requirement of the customer. Generally, the materials selected for slew band is normally C45 and En19 or 42CrMO4. Excavator and crawler applications plus the boom cranes generally have the materials as 50Mn. The balls are made of High chromium steel, generally denoted by 100Cr6 and the cages are created from either nylon 6 or nylon 66 based on the load conditions.
We makes slewing ring bearings for use in a variety of demanding industries such as heavy equipment, oil and gas, medical systems, renewable energy and semiconductor production. These versatile bearings are specifically made to handle large, heavy, slow-oscillating loads like those in cranes, booms and lifts, yet can be used in high-reliability applications such as for example CT scanners and industrial positioners.
