Detailed Description

SKF BR931145 is a front hub assembly designed for Lexus IS front wheel service where a complete wheel-end replacement is needed. The X-Tracker high-performance hub design uses a double row angular contact ball bearing arrangement to increase bearing capacity and improve hub stiffness compared with a tapered bearing hub design. That construction supports stable handling and braking performance under demanding driving conditions.
