Slewing bearings comprise an inner ring and an outer ring, one of which usually incorporates a gear. Together with attachment holes in both rings, they enable an optimized power transmission with a simple and quick connection between adjacent machine components. The bearing raceways, in conjunction with the rolling elements and cages or spacers, are designed to accommodate loads acting singly or in combination, and in any direction.
SKF manufactures standard and customized slewing bearings in various designs, with outside diameters from 0,1 to 18 m to meet the demands of particular applications.
Depending on their design, slewing bearings have the following features:
Selecting the appropriate slewing bearing can be a challenge, particularly if there are stringent technical, reliability or economic demands. In these cases, for example, SKF application engineering service can provide advanced calculations and simulations utilizing state-of-the-art analyse methods to optimize and validate the best design to meet the customer requirements.
SKF also offers worldwide a wide range of added value services for slewing bearings, including remanufacturing. A slewing bearing with only 30% left of its calculated service life can be well worth remanufacturing. SKF’s standardized remanufacturing processes can extend significantly the service life of critical equipment.
All of these combine to improve rotating equipment performance and reduce total cost of ownership.
SKF offers high-performance slewing bearings for a wide range of applications, including:
Wind turbines must cope with many extremes, including rough weather and enormous loads. Their remote location, and the need to generate more power, are two factors that make their design even more challenging. The SKF High Endurance Slewing Bearing was developed to meet these challenges.
With the tough, heavy-duty conditions of the mining industry, excavators, bucket wheel excavators and stackers / reclaimers are up against a real challenge. Slewing bearing solutions are vital for the performance and reliability of these applications.
Replacing industrial bearings can be expensive and energy-consuming. Bearing remanufacturing offers a cheaper, more environmentally sustainable option. We use a combination of reused, repaired and new parts to rebuild your bearing to the specifications of the original manufactured product.
