Slewing Bearing

Slewing bearing is identical to regular bearings, it assembly by rings and rollers. On the other hand, compare on track bearings, slewing bearing includes a lot of differences. Normally, slewing bearing offers huge dimensions, OD usually betwwen 0.4m to 10m, plus some even to 40m. Under normal situations, slewing bearing operating in a low speed, high load state. Slewing bearing includes mounting holes, lubricating holes and sealing system. It has small stucture, convenience to steer rotate, simple unit installation and easy maintenance etc.

EPT slewing ring bearings are available in many patterns with internal, external or without gear. The low cross section, hefty load capability and integrated equipment make these bearings great structure components. Slewing band bearings are trusted in construction machinery, mining equipment and several other industrial products.
Slewing bearing can be a sizable of bearing with unique structure that may bear integrated load like axle load, radial load and overturning load. It combines support, rotating, transmitting, fixed, sealed, anti-corrosion and additional functions into one device. Trusted in lifting machinery, construction machinery, transmitting machinery, mining and metallurgy machinery, medical products and radar, ship, wind power and additional industries.

Slewing Ring Bearings are precision created to manage a number of load types including radial, axial, moment or a combination of each. Their particular construction and compact footprint help facilitate simple mounting and repair. Seals are common for retaining grease and keeping contaminants out. Re-lubricating holes are incorporated into the style, evenly distributed around the bearing, to allow for grease replenishment which assists reduce friction and use and extend bearing lifestyle.
The Single-Row Ball type Slewing Ring have four points with one row. They could bear axial load, radial load and tilting instant at the same time. And they are made up of two seat rings, which design in small structure and light weight, steel ball contact with the circular raceway at four tips. There are three types of this kind of single row 4 items get in touch with ball slewing bearing: without gear bearing (non tooth), external gear bearing (exterior tooth), and Internal gear bearing (internal tooth).
EPT slewing band bearings can support radial, axial and tilting point in time loads performing either singly or perhaps in combination and in 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, 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 ensure correct assortment for the slewing bearing. The material assortment is done based on the input parameters and the requirement of the client. Generally, the materials selected for slew band is usually C45 and En19 or 42CrMO4. Excavator and crawler applications along with the boom cranes generally have the material as 50Mn. The balls are created from High chromium steel, generally denoted by 100Cr6 and the cages are constructed of either nylon 6 or nylon 66 based on the load conditions.
We makes slewing ring bearings for use in a number of demanding industries such as for example heavy equipment, oil and gas, medical systems, renewable energy and semiconductor developing. These versatile bearings happen to be specifically designed to handle large, large, slow-oscillating loads like those in cranes, booms and lifts, yet can also be used in high-reliability applications such as CT scanners and professional positioners.
