32909X Tapered Roller Set-Metric Series

The 32909X is a metric tapered roller bearing set from the 329 series with a 45 mm bore diameter. Tapered roller bearings use conical rollers arranged between inner and outer raceways to handle combined radial and axial loads in a compact design.

These bearings are commonly used in automotive wheel hubs, gearboxes, industrial transmissions, and machine tool spindles where durability under heavy loads and precise axial positioning are required. The set configuration includes both cup and cone components for complete assembly.
