Slewing Bearing

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

EPT slewing band bearings can be found in many styles with internal, external or perhaps without gear. The low cross section, large load capability and integrated equipment make these bearings ideally suited structure components. Slewing band bearings are trusted in construction machinery, mining products and many other industrial products.
Slewing bearing is normally a huge of bearing with exceptional structure that could bear integrated load just 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, development machinery, tranny machinery, mining and metallurgy machinery, medical gear and radar, deliver, wind power and other industries.

Slewing Ring Bearings happen to be precision built to manage many different load types which includes radial, axial, moment or perhaps a combination of every. Their unique construction and small footprint help facilitate ease of mounting and protection. Seals are typical 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 helps reduce friction and don 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 instant as well. And they are made up of two seat bands, which design in small structure and light weight, steel ball contact with the circular raceway at four points. There will be three types of the sort of single row 4 things speak to ball slewing bearing: without gear bearing (non tooth), external gear bearing (exterior tooth), and Internal gear bearing (internal tooth).
EPT slewing ring bearings can support radial, axial and tilting minute loads performing 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 a single bearing, which 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 so are particularly simple to install.

The ball size is normally 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 happen to be calculated using software to ensure correct assortment for the slewing bearing. The material collection is done based on the type parameters and the requirement of the client. Generally, the material selected for slew band is certainly C45 and En19 or 42CrMO4. Excavator and crawler applications plus the boom cranes generally have the materials as 50Mn. The balls are made of High chromium metal, generally denoted by 100Cr6 and the cages are made of either nylon 6 or nylon 66 depending on the load conditions.
We makes slewing ring bearings for use in a number of demanding industries such as for example heavy equipment, coal and oil, medical systems, renewable energy and semiconductor manufacturing. These versatile bearings are specifically made to handle large, hefty, slow-oscillating loads like those in cranes, booms and lifts, yet can also be used in high-accuracy applications such as for example CT scanners and professional positioners.
