Rollers with end profiling set new standard

Roller press

Schaeffler spherical roller bearings with bore diameters from 500mm and above now even more durable

SCHAEFFLER say they are successively introducing new rolling elements in all 241-Series spherical roller bearings in X-life quality with bore diameters of 500mm and above. The new barrel rollers are characterized by their enhanced end profiling – an optimized micro-geometry on the ends of the rollers that makes them significantly more robust in use.

While spherical roller bearings with non-profiled rollers show material wear due to friction after a short operating time, the edge pressure caused by abrasive material wear is at least 20% lower on bearings with profiled rollers and operating life is increased by up to 15%, resulting in increased operational reliability and machine availability.

Schaeffler say the new bearings featuring rollers with end profiling retain all of their predecessors’ X-life characteristics, including optimized internal design with increased load-carrying capacity, improved surface quality, and the floating central rib that effectively reduces friction. The option of equipping the bearings with seals that do not affect the design envelope, also remains unchanged.
