Product Details

SW D252 Precision Deep Groove Ball Bearing | 50x90x23mm | High Speed & Heavy Load Industrial Grade

The SW D252 Deep Groove Ball Bearing is engineered for critical industrial applications demanding high reliability and exceptional rotational precision. Manufactured using proprietary high-grade bearing steel (SAE 52100 equivalent) and precision-ground to P5 (ABEC 5) dimensional tolerances, the D252 ensures minimal noise, vibration, and thermal expansion under continuous operation. Featuring an optimized internal geometry and a high-strength pressed steel cage, this bearing delivers superior dynamic load capacity (Cr) compared to standard series, making it ideal for systems subjected to variable or shock loading. The standard C3 internal clearance allows for proper compensation in environments with significant temperature differentials. Designed specifically to maximize Mean Time Between Failure (MTBF) in demanding machinery, the SW D252 is the superior choice for reducing unplanned downtime and lowering total cost of ownership (TCO). Its robust sealing arrangement (either open or equipped with low-friction shields/seals) protects the internal components from industrial contaminants, extending lubricant life and maintenance intervals in challenging environments such as pumps, gearboxes, industrial fans, and medium-to-large electric motors. Trust the SW D252 for consistent, high-performance operation where reliability cannot be compromised.

Key Features

  • P5/ABEC 5 Dimensional Precision for reduced vibration and thermal stress.
  • Engineered for high-speed operation (up to 11,000 rpm) in demanding applications.
  • Optimized Internal Geometry significantly increases dynamic load rating (Cr).
  • Proprietary SW Heat Treatment enhances surface hardness and wear resistance.
  • Available with C3 internal clearance, ensuring stable performance across wide temperature variances.
  • Reduced friction sealing options available for extended service intervals (suffix required).
