Slewing Bearing

Slewing bearing is same as typical bearings, it assembly by rings and rollers. Even so, compare to normal bearings, slewing bearing has a lot of variances. Normally, slewing bearing has huge dimensions, OD usually betwwen 0.4m to 10m, and some even to 40m. Under normal circumstances, slewing bearing functioning in a minimal speed, high load condition. Slewing bearing comes with installation holes, lubricating holes and sealing gadget. It has small stucture, convenience to guide rotate, simple unit installation and easy maintenance etc.

EPT slewing ring bearings are available in many patterns with internal, external or without gear. The reduced cross section, hefty load capacity and integrated gear make these bearings preferred structure components. Slewing ring bearings are widely used in engineering machinery, mining gear and many other industrial products.
Slewing bearing is a large of bearing with specialized structure that can 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 unit. Trusted in lifting machinery, construction machinery, transmitting machinery, mining and metallurgy machinery, medical apparatus and radar, ship, wind power and other industries.

Slewing Ring Bearings are precision built to manage a number of load types which includes radial, axial, moment or perhaps a combination of every. Their unique construction and compact footprint help facilitate simple mounting and protection. 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 assists reduce friction and have on 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 point in time at the same time. And they are composed of two seat rings, which design in compact structure and light-weight, steel ball connection with the circular raceway at four tips. There will be three types of the sort of single row 4 tips contact ball slewing bearing: without gear bearing (non tooth), exterior gear bearing (external tooth), and Internal equipment bearing (internal tooth).
EPT slewing band bearings can support radial, axial and tilting point in time loads performing either singly or in combination and in virtually any direction. Therefore, you’ll be able to replace the combination arrangement of radial and axial bearings by a single bearing, that will measurably reduce the overall expense and simplify the look. Slewing rings are sealed on both sides, lubricated with top quality grease, could be relubricated via lubrication nipples and are particularly simple to install.

The ball size is generally chosen with respect 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 selection is done predicated on the suggestions 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 have the material as 50Mn. The balls are constructed of High chromium metal, generally denoted by 100Cr6 and the cages are created from either nylon 6 or nylon 66 depending on the load conditions.
We makes slewing ring bearings for use in various demanding industries such as for example heavy equipment, oil and gas, medical systems, renewable strength and semiconductor making. These versatile bearings are specifically made to handle large, large, slow-oscillating loads like those in cranes, booms and lifts, yet can be used in high-precision applications such as for example CT scanners and commercial positioners.
