The Nachi 7907CYU/GLP4 is a super precision angular contact ball bearing designed for high-performance applications, featuring a 35mm inner diameter, 55mm outer diameter, and 10mm width, with ABEC-7 (P4) quality for exceptional dimensional and running accuracy. It operates with a 15° contact angle, includes a phenolic or polyamide cage for reduced friction, and is ground for universal duplexing with a light preload (GL) for optimal spindle performance. Made in Japan, this bearing is ideal for demanding machinery requiring reliability and precision. The Nachi 6218NR is a radial ball bearing with a 90mm bore, 160mm OD, and snap ring for secure mounting, suitable for industrial applications where axial retention is critical. Both bearings exemplify Nachi’s commitment to quality, durability, and precision engineering.
