SW 628 ZZ Deep Groove Ball Bearing - 8x24x8 mm, Double Shielded, High Precision
The SW 628 ZZ deep groove ball bearing is engineered for high-speed operation and reliable performance in demanding industrial environments. Featuring a robust design with high-quality Chrome Steel (AISI 52100) construction, this bearing handles moderate radial and minor axial loads with exceptional precision. The 'ZZ' designation confirms the presence of non-contact metallic shields on both sides, providing excellent protection against debris and contaminants while retaining the factory-applied long-life grease. This design minimizes frictional drag compared to contact seals, making the 628 ZZ ideal for applications requiring higher rotational speeds and extended service intervals without manual relubrication.
As a crucial component in rotational equipment, the SW 628 ZZ ensures maximum uptime and low total cost of ownership (TCO). Its standardized dimensions (8mm bore, 24mm OD) allow for seamless integration into electric motors, power tools, small pumps, and robotics across various manufacturing sectors. SW maintains stringent quality control standards, ensuring consistent internal geometry, smooth running characteristics, and reduced vibration. Selecting the SW 628 ZZ means investing in proven durability and superior operational efficiency designed to meet the rigorous demands of 24/7 industrial applications.
