Slewing Bearing

Slewing bearing is same as regular bearings, it assembly by rings and rollers. However, Shaft Clamp china compare on track bearings, slewing bearing includes a lot of variances. Normally, slewing bearing provides huge dimensions, OD generally betwwen 0.4m to 10m, plus some even to 40m. Under normal circumstances, slewing bearing operating in a low speed, high load condition. Slewing bearing includes installation holes, lubricating holes and sealing product. It has compact stucture, convenience to guide rotate, simple installation and easy repair etc.

EPT slewing ring bearings can be found in many models with internal, external or without gear. The low cross section, weighty load capability and integrated gear make these bearings best structure components. Slewing band bearings are trusted in construction machinery, mining tools and several other industrial products.
Slewing bearing is normally a large of bearing with unique structure that could bear integrated load like axle load, radial load and overturning load. It combines support, rotating, tranny, fixed, sealed, anti-corrosion and different functions into one product. Widely used in lifting machinery, construction machinery, transmission machinery, mining and metallurgy machinery, medical tools and radar, ship, wind power and other industries.

Slewing Ring Bearings are precision built to manage many different load types including radial, axial, moment or a combination of each. Their unique construction and small footprint help facilitate ease of mounting and protection. Seals are standard for retaining grease and keeping contaminants out. Re-lubricating holes are included into the design, evenly distributed around the bearing, to permit for grease replenishment which allows reduce friction and wear 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 instant concurrently. And they are made up of two seat rings, which design in compact structure and light weight, steel ball connection with the circular raceway at four tips. There happen to be three types of this kind of single row 4 points contact ball slewing bearing: without equipment bearing (non tooth), exterior gear bearing (exterior tooth), and Internal gear bearing (internal tooth).
EPT slewing ring bearings can support radial, axial and tilting moment loads acting either singly or perhaps in combination and in virtually any direction. Therefore, it is possible to replace the combination arrangement of radial and axial bearings by an individual bearing, that will measurably reduce the overall cost and simplify the design. 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 coming on the Slewing bearing. It varies from 10 mm to 60 mm. The loads are calculated using software to make sure correct selection for the slewing bearing. The material assortment is done based on the input parameters and the necessity of the client. Generally, the material selected for slew ring is certainly C45 and En19 or 42CrMO4. Excavator and crawler applications along with the boom cranes generally possess the material as 50Mn. The balls are created from High chromium steel, generally denoted by 100Cr6 and the cages are made from either nylon 6 or nylon 66 depending on the load conditions.
We makes slewing band 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, hefty, slow-oscillating loads like those in cranes, booms and lifts, yet can even be used in high-accuracy applications such as CT scanners and commercial positioners.
