Slewing Bearing

Slewing bearing is identical to common bearings, it assembly by rings and rollers. On the other hand, compare on track bearings, slewing bearing has a lot of variances. Normally, slewing bearing provides huge dimensions, OD usually betwwen 0.4m to 10m, and some even to 40m. Under normal conditions, slewing bearing working in a low speed, high load condition. Slewing bearing comes with installation holes, lubricating holes and sealing system. It has compact stucture, convenience to guide rotate, simple set up and easy repair etc.

EPT slewing band bearings can be purchased in many patterns with internal, external or without gear. The low cross section, hefty load potential and integrated gear make these bearings ideally suited structure components. Slewing ring bearings are trusted in development machinery, mining products and several other industrial products.
Slewing bearing can be a huge of bearing with exceptional structure that could bear integrated load like axle load, radial load and overturning load. It combines support, rotating, transmission, fixed, sealed, anti-corrosion and different functions into one unit. Widely used in lifting machinery, structure machinery, tranny machinery, mining and metallurgy machinery, medical tools and radar, ship, wind power and different industries.

Slewing Ring Bearings will be precision built to manage various load types which include radial, axial, moment or a combination of every. Their unique construction and compact footprint help facilitate simple mounting and maintenance. Seals are typical for retaining grease and keeping contaminants out. Re-lubricating holes are integrated into the design, evenly distributed around the bearing, to allow for grease replenishment which assists reduce friction and put on and extend bearing your life.
The Single-Row Ball type Slewing Ring have four points with one row. They could bear axial load, radial load and tilting second simultaneously. And they are made up of two seat bands, which design in compact structure and light-weight, steel ball contact with the circular raceway at four tips. There happen to be three types of this kind of single row 4 items contact ball slewing bearing: without equipment bearing (non tooth), exterior gear bearing (external tooth), and Internal gear bearing (internal tooth).
EPT slewing band bearings may support radial, axial and tilting second loads performing either singly or in combination and in any direction. Therefore, it is possible to replace the combination set up of radial and axial bearings by an individual bearing, that will measurably decrease the overall expense and simplify the design. Slewing rings will be sealed on both sides, lubricated with top quality grease, can be relubricated via lubrication nipples and are particularly easy 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 are calculated using software to make sure correct collection for the slewing bearing. The material variety is done based on the input parameters and the requirement of the client. Generally, the material selected for slew ring is definitely 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 metal, generally denoted by 100Cr6 and the cages are made from either nylon 6 or nylon 66 based on the load conditions.
We makes slewing band bearings for use in a number of demanding industries such as for example heavy equipment, oil and gas, medical systems, renewable strength and semiconductor manufacturing. These versatile bearings will be specifically designed to handle large, weighty, slow-oscillating loads like those in cranes, booms and lifts, yet can also be used in high-precision applications such as CT scanners and commercial positioners.
