Slewing Bearing

Slewing bearing is same as normal bearings, it assembly by rings and rollers. Nevertheless, compare to normal bearings, slewing bearing includes a lot of distinctions. Normally, slewing bearing features huge dimensions, OD generally betwwen 0.4m to 10m, plus some even to 40m. Under normal instances, slewing bearing operating in a low speed, high load state. Slewing bearing includes installation holes, lubricating holes and sealing system. It has small stucture, convenience to steer rotate, simple assembly and easy repair etc.

EPT slewing band bearings are available in many patterns with internal, external or without gear. The reduced cross section, weighty load capacity and integrated gear make these bearings suitable structure components. Slewing ring bearings are trusted in building machinery, mining devices and several other industrial products.
Slewing bearing is certainly 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, transmitting, fixed, sealed, anti-corrosion and different functions into one unit. Widely used in lifting machinery, development machinery, transmitting machinery, mining and metallurgy machinery, medical gear and radar, deliver, wind power and other industries.

Slewing Ring Bearings will be precision built to manage a range of load types including radial, axial, moment or Shaft Clamp china perhaps a combination of every. Their particular construction and compact 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 style, evenly distributed around the bearing, to permit for grease replenishment which allows reduce friction and wear and extend bearing life.
The Single-Row Ball type Slewing Band have four points with one row. They could bear axial load, radial load and tilting moment at the same time. 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 tips. There will be three types of the sort of single row 4 factors speak to ball slewing bearing: without gear bearing (non tooth), external gear bearing (external tooth), and Internal equipment bearing (internal tooth).
EPT slewing ring bearings can support radial, axial and tilting instant loads performing 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 an individual bearing, that may measurably decrease the overall cost and simplify the design. Slewing rings happen to be sealed on both sides, lubricated with top quality grease, could be relubricated via lubrication nipples and are particularly easy to install.

The ball size is normally chosen with regards to the axial load and radial load coming on the Slewing bearing. It varies from 10 mm to 60 mm. The loads will be calculated using software to make sure correct collection for the slewing bearing. The material variety is done based on the suggestions parameters and the necessity of the customer. Generally, the materials selected for slew ring is C45 and En19 or 42CrMO4. Excavator and crawler applications along with the boom cranes generally possess the material as 50Mn. The balls are made of High chromium steel, generally denoted by 100Cr6 and the cages are constructed with either nylon 6 or nylon 66 based on the load conditions.
We makes slewing ring bearings for use in a range of demanding industries such as heavy equipment, oil and gas, medical systems, renewable strength and semiconductor production. 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 for example CT scanners and industrial positioners.
