Bearing

The BRINN TRANSMISSION Bearing (Part No. 71015) is a precision needle bearing engineered for high-performance transmission applications. This counter shaft bearing features a 1.030-inch inner diameter and 1.309-inch outer diameter, designed to support the demanding rotational loads found in racing and high-output transmission builds. The compact 2.3 x 1.55 x 2.65-inch profile and lightweight 0.1 lbs construction make it ideal for transmission specialists and performance shops integrating Brinn transmission components into custom automotive builds.

As a needle bearing designed for counter shaft duty, this component handles the precise alignment and load distribution critical to smooth gear engagement and power transmission efficiency. The specified bore and outer diameters ensure exact fit within Brinn transmission assemblies, where tolerances directly impact shift quality, noise levels, and longevity under racing conditions. Needle bearings like this 71015 model excel at supporting side loads while maintaining minimal friction, a key advantage in performance transmissions where heat generation must be controlled and mechanical efficiency maximized.

This bearing is essential for builders installing Brinn transmission systems in drag racing, road racing, and high-horsepower street applications. Brinn transmissions are recognized in the automotive performance community for their robust architecture and ability to handle power outputs that exceed factory-transmission limits. Sourcing OEM-quality bearings like this ensures the transmission assembly performs as engineered and maintains the reliability expected in competition and sustained high-load driving environments.

Proper bearing selection is critical when rebuilding or assembling high-performance transmissions. Counterfeit or substandard bearings can introduce play, accelerate wear, and compromise shift precision—problems that become apparent only under dynamic load. This OEM Brinn part guarantees fitment and performance consistency across the transmission assembly, a foundational requirement for any serious transmission build.
