Product Details

CR 61821 Series Thin Section Deep Groove Ball Bearing (105x130x12) | High Precision Industrial Grade

The CR 61821 (105x130x12) Deep Groove Ball Bearing is engineered for applications demanding high rotational accuracy within severe space constraints. Classified within the 61800 thin-section series, this bearing features a robust construction that delivers exceptional radial and moderate axial load support while maintaining a minimal cross-sectional profile (12mm width). Manufactured using premium high-carbon chromium steel (typically SAE 52100), the CR bearing minimizes friction and heat generation, ensuring prolonged service life and outstanding operational reliability in high-speed machinery. It is optimally suited for precise positioning systems, compact gearboxes, robotics, and complex textile machinery where every millimeter of space is critical. Designed for maximum performance under exacting industrial conditions, the CR 61821 offers a dynamic load rating (Cr) optimized for continuous duty cycles. This component excels in environments requiring stringent runout tolerances and reduced noise levels. The bearing surfaces are precision-honed, promoting smooth operation and lower maintenance requirements compared to standard cross-section alternatives. Selecting this CR bearing ensures the deployment of a reliable, high-specification component that meets the rigorous demands of modern, compact industrial equipment, guaranteeing improved machine uptime and reduced total cost of ownership.

Key Features

  • Ultra-thin 12mm cross-section design for superior space efficiency.
  • High Basic Dynamic Load Rating (Cr = 25.0 kN) suitable for demanding radial loads.
  • Precision-engineered raceways ensure low operational vibration and noise.
  • Constructed from premium CR steel, offering exceptional fatigue life.
  • Ideal solution for compact robotics, precision measurement tools, and machine spindles.
