Radial Needle Roller

The BERT Transmissions Radial Needle Roller (Part Number 20) is a precision transmission bearing designed for high-performance applications, particularly in drag racing and modified vehicles. This needle roller bearing is engineered to withstand extreme load cycles and shock loads, ensuring reliability in counter-shaft designs where performance is critical.

With an inner diameter of 1.045 inches and an outer diameter of 1.300 inches, this bearing provides superior radial load capacity in a compact design compared to traditional ball bearings. The needle roller geometry distributes loads across a larger contact area, reducing stress concentration and extending the bearing's lifespan under high-velocity gear mesh conditions typical of modified manual transmissions.

Builders and restorers working with BERT late-model and modified transmissions will find this bearing essential, especially in competitive environments where transmission reliability is paramount. Proper selection and installation of bearings like this one are crucial to prevent premature wear and catastrophic failure during high-RPM operations.
