Product Description

The F-612300.05.NUP-C01 is a precision-engineered Cylindrical Roller Bearing designed specifically for Buick CVT (Continuously Variable Transmission) automatic gearboxes, featuring dimensions of 33mm x 75mm x 19mm (Inner Diameter x Outer Diameter x Width). Manufactured from premium GCr15 chrome steel and incorporating a full complement (no cage) design, this bearing maximizes roller count to deliver outstanding radial load capacity and rigidity within a compact footprint. The NUP structural configuration—with integral flanges on both sides of the outer ring and one side of the inner ring—provides excellent axial location and facilitates easy mounting, making it ideal for demanding automotive transmission environments.

This open-type bearing ensures smooth, low-friction rotation, high wear resistance, and reliable performance under the variable torque and speed conditions typical of CVT systems. Available in P0, P6, and P5 precision grades, it guarantees stable accuracy, minimal vibration, and extended service life—critical attributes for modern automatic transmissions where precision and durability are paramount.
