Slewing Bearing

Slewing bearing is same as normal bearings, it assembly simply by rings and rollers. Even so, compare to normal bearings, slewing bearing includes a lot of dissimilarities. Normally, slewing bearing has huge dimensions, OD usually betwwen 0.4m to 10m, plus some even to 40m. Under normal instances, slewing bearing functioning in a low speed, high load state. Slewing bearing comes with installation holes, lubricating holes and sealing machine. It has small stucture, convenience to steer rotate, simple unit installation and easy protection etc.

EPT slewing band bearings can be purchased in many patterns with internal, external or without gear. The reduced cross section, large load capacity and integrated equipment make these bearings preferred structure components. Slewing ring bearings are trusted in engineering machinery, mining equipment and many other industrial products.
Slewing bearing is certainly a large of bearing with distinctive structure that can bear integrated load like axle load, radial load and overturning load. It combines support, rotating, tranny, fixed, sealed, anti-corrosion and additional functions into one product. Trusted in lifting machinery, engineering machinery, transmitting machinery, mining and metallurgy machinery, medical devices and radar, ship, wind power and different industries.

Slewing Ring Bearings are precision built to manage a variety of load types including radial, axial, moment or perhaps a combination of every. Their unique construction and compact footprint help facilitate ease of mounting and protection. Seals are common for retaining grease and keeping contaminants out. Re-lubricating holes are incorporated into the design, evenly distributed around the bearing, to permit for grease replenishment which assists reduce friction and put on 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 at the same time. And they are composed of two seat rings, 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 sort of single row 4 tips contact ball slewing bearing: without gear bearing (non tooth), exterior gear bearing (external tooth), and Internal equipment bearing (internal tooth).
EPT slewing band bearings can support radial, axial and tilting point in time loads performing either singly or in combination and in virtually any direction. Therefore, you’ll be able to replace the combination arrangement of radial and axial bearings by a single bearing, that will measurably reduce the overall price and simplify the look. Slewing rings are sealed on both sides, lubricated with high quality grease, could be relubricated via lubrication nipples and are particularly easy to install.

The ball size is Shaft Clamp china 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 happen to be calculated using software to ensure correct variety for the slewing bearing. The material variety is done predicated on the type parameters and the requirement of the client. Generally, the materials selected for slew ring is normally C45 and En19 or 42CrMO4. Excavator and crawler applications along with the boom cranes generally possess the materials 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 based on the load conditions.
We makes slewing band bearings for use in a variety of demanding industries such as heavy equipment, coal and oil, medical systems, renewable strength and semiconductor production. These versatile bearings will be specifically designed to handle large, serious, 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 professional positioners.
