Slewing bearing is identical to regular bearings, it assembly by rings and rollers. On the other hand, compare to normal bearings, slewing bearing includes a lot of differences. Normally, slewing bearing offers huge dimensions, OD usually betwwen 0.4m to 10m, and 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 can be purchased in many patterns with internal, Shaft Clamp china 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 huge 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, engineering machinery, transmitting machinery, mining and metallurgy machinery, medical products and radar, ship, wind power and additional industries.

Slewing Ring Bearings happen to be precision created to manage a range of load types including radial, axial, moment or a combination of every. Their unique construction and small footprint help facilitate simple mounting and maintenance. Seals are standard for retaining grease and keeping contaminants out. Re-lubricating holes are included into the design, evenly distributed around the bearing, to allow for grease replenishment which facilitates reduce friction and put 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 moment as well. 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 things. There are three types of the sort of single row 4 details contact ball slewing bearing: without gear bearing (non tooth), exterior gear bearing (external tooth), and Internal gear bearing (internal tooth).
EPT slewing band bearings can support radial, axial and tilting second loads performing either singly or perhaps in combination and in virtually any direction. Therefore, you’ll be able to replace the combination arrangement of radial and axial bearings by an individual bearing, that may measurably decrease the overall cost and simplify the look. 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 are calculated using software to ensure correct selection for the slewing bearing. The material assortment is done based on the source 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 metal, generally denoted by 100Cr6 and the cages are created from either nylon 6 or nylon 66 based on the load conditions.
We makes slewing ring bearings for use in a variety of demanding industries such as for example heavy equipment, oil and gas, medical systems, renewable energy and semiconductor production. 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-reliability applications such as CT scanners and professional positioners.
