6407 Deep Groove Ball Bearing For Versatile Industrial Applications & High Speed Performance | 35×100×25 mm

The 6407 is a Standard Open Deep Groove Ball Bearing from the heavy-duty 64 series, engineered to accommodate substantial radial loads and moderate axial loads in both directions. Its open configuration offers maximum design flexibility, allowing engineers to integrate custom sealing solutions or incorporate the bearing into systems with existing lubrication circuits. With a 35 mm bore, 100 mm outer diameter, and 25 mm width, this bearing is a preferred component in industrial gearboxes, electric motors, pumps, and material handling equipment where reliable operation and high speed capability are essential.



6407 Deep Groove Ball Bearing 35×100×25 mm | ISO 64 Series – Heavy Duty | Open Design (No Seals/Shields)

Featuring an optimized deep groove raceway geometry, the 6407 supports smooth, high-speed rotation with a limiting speed of up to 10,000 r/min (Oil). It delivers robust load carrying capacity, with a dynamic load rating of 56.8 kN, making it suitable for demanding industrial drive trains. The open design facilitates direct relubrication and allows the bearing to be paired with external sealing arrangements tailored to specific operating environments, ensuring long service life in both clean and moderately contaminated conditions.

Key Performance Features

01. High Load Capacity & Extended Service Life

With its robust 35×100×25 mm dimensions and precision-engineered internal geometry, the 6407 delivers exceptional dynamic and static load ratings—56.8 kN and 29.5 kN respectively—ensuring reliable performance under continuous heavy loads and intermittent shock loads.

02. Open Design for Maximum Application Flexibility

The absence of integral seals or shields allows seamless integration into custom housings, facilitates direct relubrication, and enables the use of application-specific external sealing solutions, making it adaptable to a wide range of operating conditions.

03. Precision-Ground for Low Noise & Minimal Vibration

Manufactured from high-grade chrome steel with precision-ground raceways and balls, the 6407 guarantees consistent, low-friction operation, minimizing energy loss and vibration for quiet, efficient performance even at high rotational speeds.
