SKF BR931112 Wheel Bearing and Hub Assembly - Front

SKF Front Wheel Bearing Hub Assembly BR931112

SKF BR931112 is a front wheel bearing and hub assembly built for BMW driveline and axle service where precise hub support and stable wheel-end performance matter. It uses a double row angular contact ball bearing design to increase bearing capacity and improve hub stiffness, with SKF noting up to 50 percent more stiffness than an original tapered bearing hub.

Compatible With 2017-2021 BMW 530i, front; 2017-2021 BMW 540i, front; 2019-2021 BMW 330i, front; 2019-2021 BMW X3, front; 2019-2021 BMW Z4, front; 2020-2021 BMW M340i, front; 2021 BMW 430i, front; and 2021 BMW 530e, front. This part cross-references BMW 31206866315 for the same application.

Detailed Description

SKF BR931112 is designed for front wheel-end replacement on select BMW 330i, 430i, 530e, 530i, 540i, M340i, X3, and Z4 models. The hub assembly is built around SKF wheel-end technology and is intended to restore proper wheel support, reduce play at the hub, and maintain stable braking and steering feel. The X-Tracker design uses a double row angular contact ball bearing arrangement to increase load capacity and improve stiffness under demanding driving conditions. If you are servicing a BMW front hub with OE-style fitment requirements, BR931112 provides a direct replacement path for the listed vehicles.

What It Helps Fix

• Front wheel bearing noise or growling
• Excessive hub play or looseness
• Vibration felt through the steering wheel
• Uneven braking feel from worn wheel-end components
• Handling instability caused by a worn front hub assembly

Installation Notes and Tips

Verify the vehicle’s front application and OE part number before installation. Inspect the knuckle, axle interface, and surrounding suspension components for wear or damage that could affect hub performance. Follow BMW service procedures and torque specifications during installation, and confirm smooth wheel rotation and proper brake operation after assembly.

Quality Assurance

SKF has more than 100 years of wheel-end engineering experience, and BR931112 is manufactured to SKF quality standards for durability and safety-focused performance. The X-Tracker hub design is intended for demanding use where consistent wheel support and braking response are important.
