cylindrical roller bearing / radial / steel / heavy-duty
RKB produces cylindrical roller bearings in various design styles, sizes and dimension series.
RKB heavy duty radial cylindrical roller bearings are designed to provide the highest possible radial capacity for the given cross section and to perform under heavy radial loads. These bearings incorporate improved internal proportions developed through computer assisted optimization studies, to make the maximum use of the total available cross-sectional area. The rollers have controlled contour to redistribute end stress concentration and provide more uniform distribution of the applied loads (suffix ZB). Their surface finishing maximizes lubricant film formation and optimizes rolling motion.
The standard ISO assortment of RKB production program includes single and double row bearings with a cage that can accommodate heavy radial loads and operation at high speeds.
A complete range in various executions of full complement of rollers suitable for more heavy loads at moderate speeds is also available.
Large size bearings can be supplied with surface treated rollers (suffix B).
In addition to the standard assortment, RKB cylindrical roller bearing range is comprehensive of open and sealed multi row for rolling mills in many executions and designes, backing bearings for cold rolling mills and indexing roller units for continuous furnace.
