32309

The 32309 is a metric single-row tapered roller bearing engineered to handle heavy combined loads where standard ball bearings might fail. With a 45mm bore, 100mm outer diameter, and 38.25mm width, this unit features a separable cup and cone assembly that simplifies mounting and maintenance in tight gearboxes or wheel hubs. Its tapered raceway geometry ensures that radial and axial forces are distributed evenly across the rollers, significantly reducing friction during high-speed operation (up to ~7,000 RPM). This specific design allows for rigid bearing applications when mounted in opposition to a second bearing, making it a reliable choice for automotive differentials, heavy-duty agricultural equipment, and industrial conveyor systems that require consistent stability under stress.

Built for longevity in demanding environments, the 32309 tapered roller bearing offers a robust solution for reducing equipment downtime. The high-grade steel construction and precise heat treatment provide exceptional resistance to fatigue and wear, even when subjected to shock loads common in mining and construction machinery. Because the inner ring assembly (cone) and outer ring (cup) are separable, mechanics can inspect, clean, and replace individual components without replacing the entire housing setup. Whether you are rebuilding a transmission or servicing a hydraulic pump, the 32309 delivers the high static and dynamic load ratings needed to keep your machinery running smoothly while minimizing maintenance costs over the component's lifespan.
