Slewing bearings comprise an inner ring and an external ring, one of which often incorporates a gear. As well as attachment holes in both rings, they enable an optimized power tranny with a simple and quick connection between adjacent machine elements. The bearing raceways, in conjunction with the rolling components and cages or spacers, are created to accommodate loads performing singly or in blend, and in any direction.
Selecting the correct slewing bearing can be a challenge, especially if there are stringent technical, reliability or perhaps economic demands. In these cases, for example, EPT application engineering program provides advanced calculations and simulations making use of state-of-the-art analyse methods to optimize and validate the best design to meet the customer requirements.
EPT also offers worldwide an array of added value offerings for slewing bearings, including remanufacturing. A slewing bearing with simply 30% kept of its calculated service life could be well worth remanufacturing. EPT’s standardized remanufacturing operations can extend significantly the service life of critical equipment.
All of these combine to improve Shaft Clamp china rotating equipment efficiency and reduce total cost of ownership.

The slewing bearing (slewing bearing) has been coated with anti-rust oil ahead of departing the factory and wrapped with film and linen. The rust-proof period of this package is normally 3-6 several months. The storage temperature should be 20±10°C, and the relative humidity isn’t more than 60%. After the expiration date, it ought to be maintained with time. The slewing bearing share should be filled with grease after one year and check the versatility of its rotation.
The slewing bearing (slewing bearing) is usually fixed on the pallet or in the package when it leaves the factory. It is available in single-part packaging and group packaging. Transportation and storage ought to be kept level, can’t be collided and squeezed, can not be rained, and the safe-keeping ought to be flat. There should be a flat separation between the stacked slewing bearings. The slewing bearing generally includes a lifting hole, which may be screwed in to the eyebolt for secure lifting.
Our four point contact ball slewing bearing comprises of two seat bands. In this slewing bearing, the balls contact with the circular raceway at four tips. The bearing can support axial force, radial pressure and resultant moment simultaneously.
The contact ball slewing bearings are small in design and light in weight. They might be used in slewing conveyors, welding manipulators, middle or small sized cranes and excavators, etc.
A slewing bearing or slew[ing] ring is a rotational rolling-element bearing or basic bearing that typically supports a heavy but slow-turning or slow-oscillating load, often a horizontal platform like a conventional crane, a swing yarder, or the wind-facing program of a horizontal-axis windmill. (To “slew” means to turn without switch of place.)
