Slewing bearing is identical to typical 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 a huge of bearing with distinctive structure that could bear integrated load just like axle load, radial load and overturning load. It combines support, rotating, transmitting, fixed, sealed, anti-corrosion and other functions into one unit. Trusted in lifting machinery, engineering machinery, tranny machinery, mining and metallurgy machinery, medical products and radar, deliver, wind power and additional industries.
Slewing Ring Bearings are precision created to manage a range of load types which include radial, axial, moment or a combination of each. Their particular construction and small footprint help facilitate ease of mounting and maintenance. Seals are standard for retaining grease and keeping contaminants out. Re-lubricating holes are integrated into the style, evenly distributed around the bearing, to allow for grease replenishment which allows reduce friction and put on and extend bearing existence.
The Single-Row Ball type Slewing Band have four points with one row. They could bear axial load, radial load and tilting minute simultaneously. And they are composed of two seat bands, which design in compact structure and light weight, steel ball connection with the circular raceway at four details. There are three types of this kind of single row 4 points contact ball slewing bearing: without equipment bearing (non tooth), exterior gear bearing (exterior tooth), and Internal equipment bearing (internal tooth).
EPT slewing band bearings may support radial, axial and tilting moment loads acting either singly or in combination and in any direction. Therefore, you’ll be able to replace the combination set up of radial and axial bearings by an individual bearing, that may measurably reduce the overall cost and simplify the design. Slewing rings are sealed on both sides, lubricated with high quality grease, can be relubricated via lubrication nipples and are particularly simple to install.
The ball size is generally chosen with regards to the axial load and radial load arriving on the Slewing bearing. It varies from 10 mm to 60 mm. The loads are calculated using software to ensure correct variety for the slewing bearing. The material selection is done based on the input parameters and the necessity of the client. Generally, the material selected for slew band is 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 with High chromium steel, generally Shaft Clamp china denoted by 100Cr6 and the cages are made from either nylon 6 or nylon 66 based 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 energy and semiconductor production. These versatile bearings will be specifically designed to handle large, major, slow-oscillating loads like those in cranes, booms and lifts, yet can be used in high-precision applications such as CT scanners and industrial positioners.
