SW 6308-ZZ Deep Groove Ball Bearing | 40x90x23mm | High Speed, Double Shielded Industrial Grade
The SW 6308-ZZ is a premium single-row deep groove ball bearing engineered for high performance and durability in demanding industrial applications. Manufactured from robust high-carbon chromium steel, this bearing conforms strictly to ISO dimensional standards (40mm bore, 90mm OD, 23mm width), ensuring seamless interchangeability and reliable operation. The 'ZZ' designation confirms that the bearing is fitted with non-contact metal shields on both sides, providing excellent protection against dust and contaminants while securely retaining the factory-applied high-performance grease. With high dynamic (Cr) and static (C0r) load ratings, the 6308-ZZ minimizes friction and heat generation, delivering exceptional operational stability even at reference speeds up to 12,000 RPM.
Designed for critical equipment like electric motors, gearboxes, industrial pumps, and ventilation systems, the SW 6308-ZZ significantly reduces the total cost of ownership through extended service life and reduced maintenance intervals. SW’s advanced internal geometry and high-precision raceway finishing ensure lower running noise and vibration characteristics compared to standard bearings. This sealed configuration is pre-lubricated for life, eliminating the need for complex relubrication systems and making it the ideal choice for environments where maintenance access is limited or contamination is a persistent concern. Trust the SW 6308-ZZ for reliable, high-speed performance under continuous load.
