6414 Deep Groove Ball Bearing Heavy Duty Series for Large Machinery | 70×180×42 mm

The 6414 open deep groove ball bearing is part of the heavy-duty 64 series, specifically designed to support high radial loads and bidirectional axial forces in large rotating equipment. Its open configuration provides engineers with the freedom to incorporate custom sealing systems or integrate the bearing into centralized lubrication circuits. With a 70 mm bore, 180 mm outer diameter, and 42 mm width, this bearing is widely specified for heavy industrial gearboxes, large electric motors, pumps, and material handling systems where durability and high-speed performance are required.



6414 Deep Groove Ball Bearing 70×180×42mm | ISO 64 Series – Heavy Duty | Open Design (No Seals/Shields)

Engineered with an optimized internal raceway geometry, the 6414 delivers smooth, high-speed operation with an oil limiting speed of 4,600 r/min. It offers a dynamic load rating of 143.0 kN and a static load rating of 103.2 kN, making it ideal for drivetrains subject to continuous heavy loads and occasional shock loads. The open design enables direct relubrication and allows the use of application-specific external seals, ensuring extended service life in both clean and dusty environments.

Key Performance Features

01. Low Friction and Quiet Operation

Manufactured from high-quality chrome steel with precision-ground raceways and balls, the 6414 operates with minimal friction and vibration. This results in lower energy consumption, reduced noise, and the ability to maintain efficiency even at higher speeds.

02. High Radial and Axial Load Capacity

The 6414's large 70×180×42 mm dimensions, combined with precision-engineered raceways, provide outstanding dynamic (143.0 kN) and static (103.2 kN) load ratings. This ensures reliable performance under heavy continuous loads and momentary peak loads in demanding industrial applications.

03. Open Configuration for Custom Lubrication and Sealing

Without integral seals or shields, the bearing can be easily incorporated into systems with existing oil or grease lubrication. It also allows engineers to select external sealing solutions best suited to the operating environment, enhancing protection against contaminants.
