Slewing Bearing

Slewing bearing is identical to common bearings, it assembly by rings and rollers. Nevertheless, compare on track bearings, slewing bearing has a lot of variations. Normally, slewing bearing offers huge dimensions, OD generally betwwen 0.4m to 10m, plus some even to 40m. Under normal instances, slewing bearing working in a low speed, high load condition. Slewing bearing comes with installation holes, lubricating holes and sealing unit. It has small stucture, convenience to guide rotate, simple unit installation and easy protection etc.

EPT slewing ring bearings are available in many patterns with internal, external or perhaps without gear. The reduced cross section, serious load potential and integrated equipment make these bearings ideally suited structure components. Slewing band bearings are widely used in development machinery, mining tools and several other industrial products.
Slewing bearing is certainly a sizable of bearing with distinctive structure that could bear integrated load just like axle load, radial load and overturning load. It combines support, rotating, transmission, fixed, sealed, anti-corrosion and additional functions into one product. Trusted in lifting machinery, construction machinery, transmitting machinery, mining and metallurgy machinery, medical devices and radar, deliver, wind power and other industries.

Slewing Ring Bearings are precision created to manage a number of load types which include radial, axial, moment or a combination of every. Their particular construction and small footprint help facilitate simple mounting and repair. Seals are typical 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 helps reduce friction and put 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 minute concurrently. And they are composed of two seat rings, which design in compact structure and light-weight, steel ball contact with the circular raceway at four tips. There are three types of the kind of single row 4 details get in touch with ball slewing bearing: without gear bearing (non tooth), exterior gear bearing (exterior tooth), and Internal equipment bearing (internal tooth).
EPT slewing band bearings may support radial, axial and tilting minute loads performing either singly or perhaps in combination and in any direction. Therefore, you’ll be able to replace the combination arrangement of radial and axial bearings by an individual bearing, that will measurably decrease the overall expense and simplify the design. Slewing rings happen to be sealed on both sides, lubricated with high quality grease, can be relubricated via lubrication nipples and 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 are calculated using software to ensure correct collection for the slewing bearing. The material collection is done predicated on the insight parameters and the necessity of the customer. Generally, the materials selected for slew band can be C45 and En19 or 42CrMO4. Excavator and crawler applications in addition to the boom cranes generally possess the materials as 50Mn. The balls are made of High chromium metal, generally denoted by 100Cr6 and the cages are constructed of either nylon 6 or nylon 66 according to the load conditions.
We makes slewing ring bearings for use in a variety of demanding industries such as heavy equipment, coal and oil, medical systems, renewable energy and semiconductor production. These versatile bearings will be specifically made to handle large, serious, slow-oscillating loads like those in cranes, booms and lifts, yet can even be used in high-precision applications such as CT scanners and commercial positioners.
