SKF tapered bearing sets are engineered and manufacturered to the highest quality standards. Their design and superior materials provide a significant increase in operational reliability under heavy loads and misaligned conditions. These bearings' precision engineering enables them to be easily adjusted on clearance or fit between the cup and cone assembly. These world-class bearing sets greatly reduce friction and increase load carrying capabilities. Each set contains a precision matched cup and cone that are specifically designed to maximize bearing performance and life. They help the installer do the job right, ensure longer bearing life, help prevent premature failure, and increase truck and trailer uptime.
