Compact tapered roller bearing unit for heavy rail applications

SKF has introduced a compact tapered roller bearing unit (CTBU) for railway operators that enables increased weight to be carried in freight cars designed for heavy hauls.

The CTBU has an axle load rated to 45 tonne, which means that operators can increase profitability by hauling more product with the same length/configuration train.

SKF claims it is the only heavy haul bearing rated to 45 tonne operational axle load on the market, and represents a transportation capacity increase from the existing 35.5 tonne axle load, and allowing customers to increase transported weight of product in existing or new wagon fleets.

Damage to rolling stock and infrastructure, plus delays to shipment represent the biggest costs for rail operators but the improved bearing life of the new class CTBU means less bearing fatigue. The result is freight cars with longer maintenance intervals and higher performance.
