Product Description

The F-629226.TR1 is a high‑performance metric single‑row tapered roller bearing featuring a specialised internal geometry optimised for automotive transmission and gearbox applications. This bearing is designed to handle the combined radial and axial loads that occur during gear meshing and shaft support, while maintaining compact dimensions and low friction for efficient power transmission.

Tapered roller bearings provide line contact between the rollers and raceways, offering superior load‑carrying capacity and rigidity compared to ball bearings of similar size. The F‑629226.TR1 is manufactured from GCr15 chrome steel with precision‑ground raceways and rollers, ensuring excellent wear resistance, dimensional stability, and fatigue strength under the cyclic loads and temperature variations typical of transmission environments. Its open design (without seals) allows for oil‑bath or forced‑circulation lubrication, which is the standard in automotive gearboxes.

The bearing’s special geometry is tailored to meet the specific load and speed requirements of transmission shafts, providing smooth operation and extended service life. The steel cage ensures reliable roller guidance at high speeds, while the availability of multiple precision grades (P0, P6, P5) allows flexible selection to match OEM specifications or aftermarket upgrade needs.
