Firewall Flange Bearing

The Firewall Flange Bearing from WEHRS MACHINE is a precision steering shaft component engineered for floor and firewall mounting applications in performance and race vehicles. This bearing serves as a critical pivot point in steering systems where the steering column passes through the vehicle's firewall, isolating vibration and supporting axial loads while maintaining smooth rotational freedom. Builders and fabricators select the Firewall Flange Bearing when original steering geometry requires relocation or when aftermarket chassis modifications demand a compact, reliable mounting solution.

Constructed from aluminum with black anodized finish, this bearing features a 3/4-inch spherical bearing element that accommodates both radial and slight angular loads inherent in steering shaft applications. The spherical design allows for minor misalignment without binding, extending bearing life and reducing noise transmission into the cabin. The flange mounting design provides a secure, bolted attachment to structural members, ensuring the bearing remains fixed while the steering shaft rotates freely through its center. Anodizing provides corrosion resistance and a durable, low-maintenance surface suitable for both street and competition environments.

Hot rodders, race car builders, and custom fabricators rely on the Firewall Flange Bearing when designing steering systems in tube-frame chassis or heavily modified vehicles where standard steering columns cannot be used. It is commonly paired with custom steering shafts and U-joint assemblies to create compact, efficient steering linkages. The compact dimensions (4.95 x 0.9 x 7.15 inches) and lightweight construction (0.31 lbs) make it ideal for weight-sensitive builds. Installation requires drilling mounting holes into the firewall or floor structure and securing the flange with Grade 5 bolts; proper alignment of the steering shaft centerline ensures long service life and predictable handling.
