01.  Versatile Open Design for System Integration

The open-type construction allows for maximum lubricant compatibility and efficient heat management. It is the ideal choice for integration into gearboxes and systems where the housing provides sealing and centralized lubrication is utilized.

02. Precision-Ground for Consistent Performance

Manufactured to exacting standards, the bearing features precision-ground raceways and high-quality steel balls. This ensures smooth, low-friction rotation, minimal vibration, and extended service life across a wide range of operating conditions.

03. High Radial Load Capacity

Constructed from premium chrome steel (SAE 52100/GCr15) and built to medium series dimensions, the 6405 is designed to withstand significant dynamic and static loads, ensuring reliability in the most demanding applications.

Design & Configuration

The 6405 is supplied as a standard open bearing, providing maximum design flexibility. It is the recommended base type for systems with effective external sealing. For standalone applications exposed to dust or moisture, sealed variants such as the 6405-2RS (double rubber seals) or 6405-ZZ (double metal shields) should be specified.

"The 6405 open deep groove ball bearing is a fundamental choice for engineers designing heavy-duty gearboxes, industrial drives, and transmission systems, where proven load capacity and integration into a lubricated system are key requirements."
