SW 6209-Z Single Shield Deep Groove Ball Bearing | 45x85x19mm | Premium Industrial Reliability
The SW 6209-Z is a highly reliable single-row deep groove ball bearing engineered for demanding industrial applications requiring robust performance and exceptional durability. Defined by its 45 mm bore, 85 mm outer diameter, and 19 mm width, the 6209 series is commonly utilized in electric motors, pumps, gearboxes, and precision machinery where radial and moderate axial loads are present. Constructed from high-quality, heat-stabilized bearing steel, this bearing offers superior fatigue life and dimensional stability, ensuring minimal vibration and extended maintenance intervals. The 'Z' designation indicates a precision pressed steel shield installed on one side, offering effective protection against contaminants while allowing the opposite open side for easier inspection or relubrication access in complex machine assemblies.
Selecting the SW 6209-Z is a strategic decision for optimizing Total Cost of Ownership (TCO). Its precision raceway geometry and optimal internal clearance (CN) minimize friction and heat generation, leading to higher operational speeds (up to 10,000 RPM) and reduced energy consumption compared to standard alternatives. As a Senior PM, we emphasize that this bearing is pre-lubricated with high-performance grease, designed to meet the rigorous demands of 24/7 industrial operations. The robust design and reliable SW manufacturing quality ensure maximum uptime, reducing unexpected failures and streamlining preventive maintenance procedures across critical plant equipment.
