The R6 series represents a mid-range option within the imperial size category; constructed from SUS304 stainless steel, it offers the dual advantages of superior rust resistance and stable load-bearing performance. Featuring deep-ground raceways and selected 304 stainless steel balls, these bearings ensure silent operation under conditions involving low speeds and high torque.
Bearing Features
Balancing material costs with performance, SUS304 delivers excellent value—avoiding the frequent maintenance required for standard steel while sidestepping the unnecessary expense of higher-grade stainless steels. Commonly found in food sorting conveyors, cleaning brush mechanisms, and automatic pool-cleaning robots, these bearings are capable of operating while submerged for extended periods in water containing low concentrations of disinfectants.
