Mounting a slewing ring bearing in the proper structure is crucial to properly distributing bearing load and stress. Without an adequate structure, bearing performance is likely to suffer. So can the performance of the seals, pinions, gears, and bolts. Therefore, mounting Kaydon Imperial Slewing Ring should be considered very early in the design process.The designer’s first task, of course, is to specify a size for the slewing bearing. The bearing manufacturer can recommend a size based on applied load and ideal mounting. In heavy equipment, for example, the primary task of the slewing bearing and its mounting structure is to handle an over-turning moment load. Also, a slewing ring bearing with integral KOYO 6304 Bearing gearing must be sized for adequate gear strength and pinion drive position. Another factor is how large the central opening in the bearing bore should be… this may have as much influence on bearing size as the maximum applied load.
