Product Description
Four Point Ball 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.

When selecting 4 point ball slewing bearings for any purpose, ultimately you want to be certain of achieving the required level of equipment performance – and at the lowest possible cost. Robustness also is very important because the conditions in which your equipment is assembled, operated and maintained may not be precisely known and may, in fact, vary over time.
In addition to the 4 point ball slewing bearing rating life, there are key factors you must consider when putting together the slewing bearing specifications for an application, including:

lubricant and supply method

shaft and housing fits

bearing clearance class

cage material and guidance

dimensional stability

precision requirements

slewing bearing sealing

mounting method and maintenance
