The 32909 (also designated as 32909X or 32909J) is a metric single-row tapered roller bearing measuring 45 mm (ID) × 68 mm (OD) × 15 mm (Width). Designed as a separable cup and cone assembly, it efficiently supports heavy combined radial and axial loads. Manufactured to ISO9001:2000 standards with options for steel or brass cages, this bearing is widely used in automotive applications, tractors, and industrial machine tools. We supply global B2B manufacturers with flexible payment terms and customized industrial packaging.
The 32909 Tapered Roller Bearing is engineered for applications requiring high rigidity and load-carrying capacity in a compact profile. As an isolation (separation) type bearing, the inner ring assembly (cone, rollers, and cage) can be installed independently from the outer ring (cup). During the installation process, the bearing's internal clearance can be precisely adjusted or pre-loaded, giving engineers strict control over shaft rigidity and running accuracy.
Please reference the metric and imperial dimensions below to ensure proper fitment on your assembly lines.

The 32909 bearing utilizes a specialized conical raceway geometry where the contact lines between the rollers and raceways intersect at a single point on the bearing axis. This provides several benefits:
Pure Rolling Motion: The intersecting geometry ensures true rolling motion along the entire length of the rollers, significantly reducing friction, heat generation, and wear.
Combined Load Handling: Engineered to handle both heavy radial forces and single-direction axial (thrust) forces simultaneously.
Material Strength: Available with standard stamped steel cages for general use, or machined brass cages for high-vibration and shock-load applications.
Thanks to its 45 mm bore and reliable load ratings, the 32909 is heavily utilized in drive systems and power transmissions:
Automotive: Gearboxes, differentials, and wheel hubs for passenger cars and tractors.
Industrial Machinery: Spindles for machine tools, textile machinery, and water pump drive shafts.
Heavy Equipment: Electric machines and agricultural harvesters.
We provide robust supply chain solutions tailored to the needs of wholesalers and original equipment manufacturers (OEMs).
Packaging: Supplied in bulk industrial packaging (tubes/trays) to speed up your assembly line, or customized single-color boxes according to the buyer’s requirement.
Quality Standard: Manufactured strictly under ISO9001:2000 quality management systems.
Payment Terms: 100% T/T, 30% T/T advance with 70% against B/L copy, 30% T/T with 70% against L/C at sight, PayPal, and Western Union.
