Thrust Needle Roller

The Thrust Needle Roller by BERT TRANSMISSIONS is a precision counter-shaft bearing engineered for high-performance and modified automatic transmissions. This needle bearing is essential for builders and enthusiasts upgrading or rebuilding Bert late-model and modified transmission applications where durability and load capacity are non-negotiable. Whether you're constructing a dedicated drag racing gearbox, street-strip hybrid, or high-horsepower street machine, this bearing isolates axial thrust loads and minimizes parasitic drag losses during gear engagement.

Needle roller bearings deliver superior load distribution across multiple rolling elements packed in a compact envelope—exactly why BERT TRANSMISSIONS specifies them for counter-shaft duty. This thrust needle roller features a 1.007-inch inner diameter and 1.540-inch outer diameter, creating a tight contact envelope optimized for the radial and axial forces generated during acceleration and deceleration cycles. The roller design reduces bearing preload creep and maintains consistent clearances even under extreme shift shock, critical when transmissions experience back-to-back full-throttle passes or sustained high-load driving. Weighing just 0.02 pounds, the bearing adds negligible mass while providing the rigidity needed for precision shift quality and longevity.

Transmission builders, drag racers, and performance shops rebuilding Bert transmissions rely on OEM-equivalent needle roller bearings like this one to restore or upgrade worn assemblies. Installation requires proper seating into the counter-shaft bore with correct preload, typically performed during full transmission assembly. This bearing is sold individually; verify your transmission's complete bearing kit requirements before ordering. For detailed fitment and installation torque specifications, consult your Bert transmission service manual or contact an authorized rebuild specialist familiar with your specific transmission generation.
