NACHI 6915ZNR Deep Groove Ball Bearings
The NACHI 6915ZNR 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 75 mm, outer diameter of 105 mm, and a width of 16 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 6915ZNR 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. Single shield, snap-ring groove, and snap ring (ZNR) combine axial retention with dust protection. The outer ring incorporates a snap-ring groove (and, where applicable, a supplied retaining ring) for simple axial location in housings – eliminating the need for separate locking devices.
Performance
Rated for a basic dynamic load capacity of 20.8 kN and a static load capacity of 19.7 kN, this bearing delivers dependable load-carrying ability and long calculated service life under correct operating conditions. Permissible speeds reach 6,200 rpm with grease lubrication and 7,200 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.
