Slewing Bearing

Slewing bearing is identical to common bearings, it assembly by rings and rollers. However, compare to normal 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 circumstances, slewing bearing functioning in a low speed, high load state. Slewing bearing includes installation holes, lubricating holes and sealing product. It has compact stucture, convenience to guide rotate, simple set up and easy protection etc.

EPT slewing band bearings can be purchased in many patterns with internal, external or without gear. The reduced cross section, major load ability and integrated equipment make these bearings best structure components. Slewing ring bearings are trusted in engineering machinery, mining products and several other industrial products.
Slewing bearing is normally a large of bearing with specialized 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 various other functions into one product. Widely used in lifting machinery, building machinery, tranny machinery, mining and metallurgy machinery, medical equipment and radar, ship, wind power and additional industries.

Slewing Ring Bearings happen to be precision created to manage a number of load types which includes radial, axial, moment or perhaps a combination of each. Their unique construction and small footprint help facilitate simple mounting and maintenance. 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 can help reduce friction and dress in and extend bearing existence.
The Single-Row Ball type Slewing Band have four points with one row. They could bear axial load, radial load and tilting second as well. 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 things. There will be three types of the sort of single row 4 things speak to ball slewing bearing: without equipment bearing (non tooth), exterior gear bearing (external tooth), and Internal equipment bearing (internal tooth).
EPT slewing band bearings may support radial, axial and tilting point in time loads acting either singly or in combination and in virtually any direction. Therefore, you’ll be able to replace the combination set up of radial and axial bearings by an individual bearing, which will measurably reduce the overall expense and simplify the look. Slewing rings will be sealed on both sides, lubricated with top quality grease, can be relubricated via lubrication nipples and so 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 Shaft Clamp china material variety is done predicated on the suggestions parameters and the requirement of the client. Generally, the material selected for slew ring is certainly C45 and En19 or 42CrMO4. Excavator and crawler applications and also the boom cranes generally possess the materials as 50Mn. The balls are constructed with High chromium metal, 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 many different demanding industries such as heavy equipment, oil and gas, medical systems, renewable energy and semiconductor production. These versatile bearings happen to be specifically designed to handle large, major, 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 professional positioners.
