The "XL" suffix in the BE series indicates that the product meets X-life quality standards, offering significant performance improvements over conventional designs:
Higher Load Carrying Capacity: By optimizing the internal structure, increasing the size of the rolling elements, and removing the inner ring center rib, the rollers are longer and larger. This increases the basic dynamic load rating by up to 15%, significantly extending bearing service life under heavy-load conditions.
Increased Speed Capability: Optimized contact geometry between the rollers and raceways, combined with improved surface finishes, reduces friction significantly. This allows for a speed increase of up to 50% compared to standard designs.
Extended Service Life: Under the same operating conditions, X-life bearings can achieve a nominal service life up to 60% longer than conventionally designed bearings.
