The Nachi 5305ZZ is a double-row angular contact ball bearing engineered for high-performance applications, featuring a 25 mm bore, 62 mm outer diameter, and 25.4 mm width for precise fitment in demanding machinery. With a 20-degree contact angle, it delivers optimized axial and radial load capacity, supporting dynamic loads up to 32,000 N and static loads up to 21,600 N for reliable operation under stress. Double metal shields provide enhanced contamination protection, while the bearing’s robust construction ensures smooth rotation at speeds up to 7,300 rpm (grease) or 10,000 rpm (oil). Made in Japan, the 5305ZZ is ideal for industrial equipment, blowers, pumps, and automotive systems where durability and precision are critical.
