The R22-ZZ is a single-row inch-series deep groove ball bearing fitted with double pressed-steel shields (ZZ), purpose-built for applications where reliable dust exclusion and low-maintenance operation are priorities. With a 1-3/8" (34.925 mm) bore, 2-1/2" (63.5 mm) outer diameter, and 9/16" (14.288 mm) width, it serves as a direct-fit solution across North American inch-dimensioned machinery platforms. The metal-shield configuration keeps friction torque lower than rubber-sealed equivalents, making this bearing a preferred selection for higher-speed assemblies including motors, textile drives, CNC spindles, conveyor roller heads, and agricultural equipment where light contamination protection is needed without sacrificing rotational performance.
