BOWER MR 5208 Double Row Angular Contact Ball Bearing | 40mm x 80mm x 30.2mm | High Precision | Gearbox & Pump Ready

The BOWER MR 5208 is a high-performance Double Row Angular Contact Ball Bearing engineered for critical industrial applications demanding superior rigidity and high combined load capacity. Designed with a standardized 40mm bore, 80mm outer diameter, and 30.2mm width, this precision bearing features a substantial contact angle, enabling it to accommodate significant radial loads alongside substantial axial loads acting in both directions. Constructed from hardened high-carbon chromium steel, the MR 5208 provides the necessary stiffness and durability required to maintain precise shaft location and reduce runout in challenging operational environments. Optimized for reliability and reduced total cost of ownership, the BOWER MR 5208 is the ideal choice for heavy-duty pumps, industrial gearboxes, and high-speed machine tool spindles where uptime is paramount. Its integrated dual-row configuration simplifies mounting and assembly compared to utilizing two single-row bearings. When you specify BOWER, you invest in reduced friction, improved thermal stability, and extended service life, ensuring maximum operational efficiency and minimizing unscheduled maintenance across your most critical machinery.

Key Features

  • Exceptional Bi-Directional Axial Load Capability due to the integrated double-row design.
  • High System Rigidity essential for maintaining accuracy in machine tool and spindle applications.
  • Reduced Friction and operating temperatures for longer grease life and reliability.
  • Precision Ground Raceway Geometry ensures quiet operation and low vibration levels.
  • Suitable for High-Speed Operation under combined load conditions in challenging industrial environments.
