Slewing bearing is identical to common bearings, it assembly by rings and rollers. On the other hand, compare to normal bearings, slewing bearing includes a lot of dissimilarities. Normally, slewing bearing offers huge dimensions, OD usually betwwen 0.4m to 10m, plus 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 device. It has compact stucture, convenience to guide rotate, simple set up and easy repair etc.
EPT slewing ring bearings are available in many styles with internal, external or perhaps without gear. The reduced cross section, large load capability and integrated gear make these bearings suitable structure components. Slewing ring bearings are trusted in structure machinery, mining equipment and many other industrial products.
Slewing bearing is usually a large of bearing with unique structure that may bear integrated load just like axle load, radial load and overturning load. It combines support, rotating, transmission, fixed, sealed, anti-corrosion and various other functions into one product. Trusted in lifting machinery, construction machinery, transmission machinery, mining and metallurgy machinery, medical gear and radar, ship, wind power and various other industries.
Slewing Ring Bearings are precision built to manage various load types which includes radial, axial, moment or a combination of every. Their unique construction and compact footprint help facilitate simple mounting and protection. Seals are typical for Shaft Clamp china 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 facilitates 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 rings, which design in small structure and light-weight, steel ball connection with the circular raceway at four tips. There happen to be three types of this kind of single row 4 items speak to 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 may measurably decrease the overall price and simplify the design. Slewing rings will be sealed on both sides, lubricated with top quality grease, could be relubricated via lubrication nipples and are particularly easy to install.
The ball size is generally chosen with regards to the axial load and radial load approaching on the Slewing bearing. It varies from 10 mm to 60 mm. The loads happen to be calculated using software to ensure correct variety for the slewing bearing. The material assortment is done based on the source parameters and the necessity of the customer. Generally, the materials selected for slew band is C45 and En19 or 42CrMO4. Excavator and crawler applications along with the boom cranes generally possess the materials as 50Mn. The balls are created from 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 band bearings for use in a variety of demanding industries such as heavy equipment, oil and gas, medical systems, renewable strength and semiconductor making. These versatile bearings are specifically made to handle large, major, slow-oscillating loads like those in cranes, booms and lifts, yet can be used in high-accuracy applications such as CT scanners and commercial positioners.
