Slewing bearing is identical to ordinary bearings, it assembly simply by rings and rollers. Even so, compare to normal bearings, slewing bearing has a lot of variations. Normally, slewing bearing features huge dimensions, OD generally betwwen 0.4m to 10m, plus some even to 40m. Under normal conditions, slewing bearing operating in a minimal speed, high load state. Slewing bearing Shaft Clamp china includes installation holes, lubricating holes and sealing device. It has compact stucture, convenience to guide rotate, simple unit installation and easy repair etc.

EPT slewing band bearings can be purchased in many designs with internal, external or perhaps without gear. The low cross section, major load capability and integrated gear make these bearings suitable structure components. Slewing band bearings are trusted in engineering machinery, mining gear and many other industrial products.
Slewing bearing can be a huge of bearing with exceptional structure that could bear integrated load like axle load, radial load and overturning load. It combines support, rotating, transmitting, fixed, sealed, anti-corrosion and other functions into one device. Trusted in lifting machinery, building machinery, transmitting machinery, mining and metallurgy machinery, medical equipment and radar, ship, wind power and other industries.

Slewing Ring Bearings happen to be precision built to manage a number of load types including radial, axial, moment or a combination of every. Their particular construction and small footprint help facilitate ease of mounting and maintenance. Seals are standard for retaining grease and keeping contaminants out. Re-lubricating holes are integrated into the design, evenly distributed around the bearing, to allow for grease replenishment which allows reduce friction and have on 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 moment as well. And they are composed of two seat bands, which design in small structure and light weight, steel ball connection with the circular raceway at four factors. There happen to be three types of this sort of single row 4 points contact ball slewing bearing: without gear bearing (non tooth), exterior gear bearing (external tooth), and Internal equipment bearing (internal tooth).
EPT slewing ring bearings may support radial, axial and tilting minute loads performing either singly or perhaps in combination and in any direction. Therefore, it is possible to replace the combination set up of radial and axial bearings by an individual bearing, that will measurably reduce the overall cost and simplify the look. 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 generally chosen with regards to the axial load and radial load approaching on the Slewing bearing. It varies from 10 mm to 60 mm. The loads happen to be calculated using software to make sure correct collection for the slewing bearing. The material assortment is done based on the type parameters and the requirement of the customer. Generally, the material selected for slew band is certainly C45 and En19 or 42CrMO4. Excavator and crawler applications in addition to the boom cranes generally possess the material as 50Mn. The balls are constructed with 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 band bearings for use in a variety of demanding industries such as for example heavy equipment, coal and oil, medical systems, renewable energy and semiconductor making. These versatile bearings will be specifically made to handle large, large, slow-oscillating loads like those in cranes, booms and lifts, yet may also be used in high-reliability applications such as CT scanners and industrial positioners.
