Slewing bearing is identical to common bearings, it assembly by rings and rollers. However, compare on track bearings, slewing bearing includes a lot of distinctions. Normally, slewing bearing features huge dimensions, OD usually betwwen 0.4m to 10m, and some even to 40m. Under normal instances, slewing bearing working in a low speed, high load state. Slewing bearing comes with installation holes, lubricating holes and sealing gadget. It has compact stucture, convenience to guide rotate, simple assembly and easy repair etc.
EPT slewing band bearings are available in many designs with internal, external or without gear. The reduced cross section, serious load potential and integrated gear make these bearings ideal structure components. Slewing band bearings are trusted in building machinery, mining devices and many other industrial products.
Slewing bearing is normally a huge of bearing with particular structure that can bear integrated load just like axle load, radial load and overturning load. It combines support, rotating, tranny, fixed, sealed, anti-corrosion and various other functions into one unit. Widely used in lifting machinery, building machinery, transmitting machinery, mining and metallurgy machinery, medical equipment and radar, ship, wind power and additional industries.
Slewing Ring Bearings will be precision built to manage a variety of load types which includes radial, axial, moment or a combination of each. Their unique construction and small footprint help facilitate ease of mounting and repair. Seals are standard for retaining grease and keeping contaminants out. Re-lubricating holes are included into the design, evenly distributed around the bearing, to permit for grease replenishment which can help 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 moment at the same time. And they are made up of two seat rings, which design in compact structure and light weight, steel ball connection with the circular raceway at four details. There happen to be three types of this sort of single row 4 things get in touch with ball slewing bearing: without equipment bearing (non tooth), external gear bearing (external tooth), and Internal equipment bearing (internal tooth).
EPT slewing band bearings may support radial, axial and tilting instant loads acting either singly or perhaps in combination and in virtually any direction. Therefore, it is possible to replace the combination set up of radial and axial bearings by an individual bearing, which will measurably decrease the overall price and simplify the look. 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 assortment for the slewing bearing. The material assortment is done based on the type parameters and the necessity of the client. Generally, the materials selected for slew ring is usually C45 and En19 or 42CrMO4. Excavator and crawler applications plus the boom cranes generally have the material as 50Mn. The balls are constructed with High chromium steel, generally denoted by 100Cr6 and the cages are made of either nylon 6 or nylon 66 based on the load conditions.
We makes slewing band bearings for use in a range of demanding industries such as heavy equipment, coal and oil, medical systems, renewable strength and semiconductor production. These versatile bearings happen to be specifically designed to handle large, serious, 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.
