NACHI 6207 Deep Groove Ball Bearings

NACHI 6207 Deep Groove Ball Bearings

The NACHI 6207 is a high-quality single-row deep groove ball bearing engineered to deliver reliable performance across a broad spectrum of industrial and commercial applications. With a bore diameter of 35 mm, outer diameter of 72 mm, and a width of 17 mm, this bearing conforms to ISO dimension standards and is a direct interchange for equivalent series bearings from other manufacturers.

Design & Construction

Manufactured by NACHI – one of Japan’s leading bearing producers – the 6207 is precision-ground from high-carbon chromium bearing steel (AISI 52100 / JIS SUJ2), heat-treated to achieve optimum hardness and fatigue resistance. The deep raceway grooves in both the inner and outer rings enable the bearing to support radial loads as well as moderate axial loads in either direction. Open design with no seals or shields, allowing free Oil and Grease flow and easy re-lubrication in service.

Performance

Rated for a basic dynamic load capacity of 25.7 kN and a static load capacity of 15.3 kN, this bearing delivers dependable load-carrying ability and long calculated service life under correct operating conditions. Permissible speeds reach 9,800 rpm with grease lubrication and 11,000 rpm with oil lubrication, making it well suited to high-speed rotating equipment. Supplied with standard CN internal clearance, this bearing is suited to the widest range of general-purpose applications.
