Ball Bearing 1/2in Ball Spline

The Ball Bearing 1/2in Ball Spline (MPN 3-07) from BERT TRANSMISSIONS is a precision roller bearing component engineered for high-performance manual transmission builds. This compact bearing assembly is essential for builders and mechanics upgrading driveline components on street and race vehicles. The ball spline design allows for axial movement while transmitting rotational torque, making it a critical wear item during transmission rebuilds or when switching to performance gearbox platforms that demand superior load handling.

Manufactured from hardened steel in natural finish, this ball bearing features a half-inch bore diameter and precision ball spline geometry that maintains tight tolerances under load cycling. The 1/2-inch ball spline specification indicates compatibility with BERT transmission input or output shafts that utilize this common spline pitch. At just 0.02 lbs with compact dimensions (3 x 0.45 x 5.55 inches), the bearing integrates seamlessly into tight transmission bell housings without adding unnecessary weight—a critical consideration for performance applications where every ounce impacts acceleration and handling balance.

This bearing suits transmission technicians, hot rod builders, and motorsport enthusiasts working on BERT performance transmissions across Chevrolet, Ford, Mopar, and other platforms. Installation requires proper shaft alignment and preload settings during transmission assembly to ensure longevity and prevent drivetrain vibration. Whether you're refreshing an aging street engine or assembling a purpose-built race gearbox, this OEM-quality bearing ensures smooth shaft operation and reliable power delivery under sustained boost or high-RPM conditions. Verify spline pitch compatibility with your specific transmission model before ordering.
