NACHI 6816ZZC3 Deep Groove Ball Bearings
The NACHI 6816ZZC3 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 80 mm, outer diameter of 100 mm, and a width of 10 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 6816ZZC3 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. Double metal shields (ZZ) protect against dust and debris on both sides while retaining the factory-filled grease.
Performance
Rated for a basic dynamic load capacity of 12.7 kN and a static load capacity of 13.3 kN, this bearing delivers dependable load-carrying ability and long calculated service life under correct operating conditions. Permissible speeds reach 6,000 rpm with grease lubrication and 7,100 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
