MARTIN 50 A 22 High-Precision Deep Groove Ball Bearing (50x90x20mm) - Heavy Industrial Reliability
The MARTIN 50 A 22 bearing is engineered for mission-critical industrial applications demanding high reliability and minimal downtime, such as large electric motors, gearboxes, and high-speed pumps. Featuring a robust Single Row Deep Groove Ball (SRDGB) design, this unit is manufactured from premium SAE 52100 high-carbon chrome steel, ensuring superior hardness and wear resistance under continuous stress. Its optimized internal geometry provides exceptional running accuracy (P6 tolerance standard) and is capable of handling combined radial and moderate axial loads effectively. With a high dynamic load rating (Cr) of 40.0 kN, the 50 A 22 is specified to extend the service life of critical rotating equipment, drastically reducing maintenance cycles and the Total Cost of Ownership (TCO).
Designed specifically for the rigorous demands of 24/7 operations, the MARTIN 50 A 22 utilizes a durable pressed steel cage for high rotational speeds up to 8,000 RPM (grease lubricated). Each bearing undergoes stringent quality assurance testing to ensure extremely low vibration and noise levels, making it an ideal choice for noise-sensitive environments and high-precision machinery like CNC spindles and auxiliary equipment. We recommend the 50 A 22 for operations where performance cannot be compromised by standard-grade components, offering guaranteed dimensional stability and reliability that meets or exceeds ISO standards for heavy machinery performance.
