01. Open Configuration for Maximum Design Flexibility

The absence of integral seals or shields allows seamless integration into custom housings, facilitates direct relubrication for extended service life, and enables pairing with application-specific external sealing solutions tailored to diverse operating environments.

02. Precision-Ground for Low Noise & Minimal Vibration

Manufactured from high-grade chrome steel with precision-ground raceways and balls, the 6409 guarantees consistent low-friction operation, minimizing vibration and energy loss while delivering quiet, efficient performance across its entire speed range.

03. Substantial Load Capacity & Long Service Life

With its robust 45×120×29 mm envelope and precision-engineered internal geometry, the 6409 delivers an impressive dynamic load rating of 77.5 kN and static load rating of 45.5 kN, ensuring reliable performance under continuous heavy loads and occasional shock loading in demanding industrial applications.

Interchange Part Numbers

This bearing conforms to international dimensional standards and is directly interchangeable with all major bearing manufacturers:

• SKF: 6409
• NSK: 6409
• FAG: 6409
• NTN: 6409
• KOYO: 6409
• Timken: 6409

Design & Configuration

The standard 6409 is supplied as an open bearing. For applications requiring built-in contamination protection, sealed variants such as 6409-2RS (double rubber seals) or shielded variants such as 6409-ZZ (double metal shields) are available as alternative configurations from stock.

"As a higher capacity member of the 64 series, the 6409 deep groove ball bearing is the preferred choice for engineers designing larger industrial machinery, pumps, and drive systems where increased load handling and reliable performance are paramount."
