NACHI 6008C3 Deep Groove Ball Bearings

The NACHI 6008C3 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 40 mm, outer diameter of 68 mm, and a width of 15 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 6008C3 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 16.8 kN and a static load capacity of 11.5 kN, this bearing delivers dependable load-carrying ability and long calculated service life under correct operating conditions. Permissible speeds reach 10,000 rpm with grease lubrication and 12,000 rpm with oil lubrication, making it well suited to high-speed rotating equipment. This variant features C3 internal clearance – a wider-than-standard radial play that accommodates thermal expansion in elevated-temperature environments such as electric motors, dryers, and heat-intensive machinery.

Typical Applications

  • Electric motors, generators, and alternators
  • Pumps, compressors, and blowers
  • Conveyor and material-handling systems
  • Agricultural and farming equipment
  • Power tools and woodworking machinery
  • Automotive ancillaries – water pumps, tensioners, idlers
  • HVAC fans, air-conditioning units, and refrigeration
  • Food and beverage processing machinery
  • Gearboxes, reducers, and transmission assemblies
  • General industrial and workshop machinery
