SKF Cassette Railway Bearings
Taper Roller Bearing Units (TBUs) used on railway rolling stock are critical to the smooth running of any rail system.
SKF has maintained a key focus in the conceptual development of new bearing designs with the ability to achieve the increased load capacities required by the global customer base. The CTBU concept requires less maintenance with an impact on cost reduction, provides higher safety and reliability and is pre-equipped with advanced component technologies that allow railway operators time to react if severe bearing conditions occur while in service.
