RUKO SLS-SPS Vapor 22,5mm Ρουλεμάν

Maintenance technicians and machine builders rely on the RUKO SLS-SPS vapor 22.5mm ball bearing for smooth, low-friction rotation in demanding industrial environments. This single-row deep groove ball bearing features a 20mm bore, 47mm outer diameter, and 14mm width, with two contact rubber seals (2RSR) to retain lubrication and block contaminants. C3 internal clearance provides extra radial play for high-speed or high-temperature applications. Manufactured from high carbon chromium steel with a sheet steel cage, it delivers dependable performance in conveyors, pumps, electric motors, and similar rotating equipment.
