Slewing bearing is identical to typical bearings, it assembly simply by rings and rollers. Even so, compare on track bearings, slewing bearing has a lot of dissimilarities. Normally, slewing bearing has huge dimensions, OD usually betwwen 0.4m to 10m, plus some even to 40m. Under normal instances, slewing bearing operating in a minimal speed, high load condition. Slewing bearing includes mounting holes, lubricating holes and sealing system. It has small stucture, convenience to guide rotate, simple unit installation and easy repair etc.
EPT slewing ring bearings can be found in many models with internal, external or without gear. The reduced cross section, large load capacity and integrated gear make these bearings best structure components. Slewing ring bearings are widely used in construction machinery, mining apparatus and several other industrial products.
Slewing bearing is definitely a huge of bearing with distinctive 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 different functions into one unit. Widely used in lifting machinery, construction machinery, transmission machinery, mining and metallurgy machinery, medical apparatus and radar, ship, wind power and additional industries.
Slewing Ring Bearings are precision built to manage many different load types which includes radial, axial, moment or perhaps a combination of each. Their particular construction and compact footprint help facilitate simple mounting and repair. Seals are common 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 allows reduce friction and use 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 second at the same time. And they are composed of two seat rings, which design in small structure and light weight, steel ball connection with the circular raceway at four factors. There will be three types of this kind of single row 4 things contact ball slewing bearing: without equipment bearing (non tooth), exterior gear bearing (external tooth), and Internal gear bearing (internal tooth).
EPT slewing band bearings can support radial, axial and tilting instant loads performing either singly or perhaps in combination and in any direction. Therefore, it is possible to replace the combination arrangement of radial and axial bearings by an individual bearing, that may measurably decrease 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 respect to the axial load and radial load coming on the Slewing bearing. It varies from 10 mm to 60 mm. The loads will be calculated using software to ensure correct collection for the slewing bearing. The material selection is done predicated on the type parameters and the necessity of the client. Generally, the materials selected for slew ring is certainly C45 and En19 or 42CrMO4. Excavator and crawler applications plus the boom cranes generally possess the material as 50Mn. The balls are constructed of High chromium metal, generally denoted by 100Cr6 and the cages are constructed of either nylon 6 or nylon 66 depending on the load conditions.
We makes slewing band bearings for use in a range of demanding industries such as for example heavy equipment, coal and oil, medical systems, renewable energy and semiconductor production. These versatile bearings will be specifically designed 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 CT scanners and professional positioners.
