The SW 6304 ZZ Deep Groove Ball Bearing is engineered for high-performance industrial applications requiring maximum reliability and reduced maintenance cycles. Featuring precision-ground raceways and high-quality steel construction, this bearing adheres to stringent ISO standards (20mm bore, 52mm OD, 15mm width). The 'ZZ' designation indicates that the bearing is equipped with two non-contact metal shields, effectively retaining factory lubricant (grease) while offering superior protection against coarse contaminants and debris common in dusty environments. Its optimal internal clearance and robust design ensure exceptional dynamic load capacity (14.0 kN), making it the ideal solution for electric motors, gearboxes, pumps, and material handling systems operating at elevated speeds.
Choosing the SW 6304 ZZ guarantees operational longevity and minimized friction loss, directly contributing to energy efficiency and machine uptime. Designed for simple installation and superior thermal management, this bearing is pre-lubricated for life under normal operating conditions, providing a true fit-and-forget component solution. We provide consistent SW quality—a dependable alternative to premium European brands—offering a critical balance of performance, load rating, and competitive total cost of ownership for OEMs and MRO operations seeking consistent quality in their supply chain.
