Product Details

CR 11801 Deep Groove Ball Bearing | High-Precision Radial Load Capacity | 12x21x5 mm

The CR 11801 Deep Groove Ball Bearing is engineered for compact, high-speed industrial applications requiring uncompromising reliability. Featuring precision-machined races crafted from through-hardened 52100 bearing steel, the 11801 delivers exceptional fatigue life and resistance to abrasive wear. This single-row configuration is optimized for handling moderate radial and light axial loads, ensuring stable operation across demanding duty cycles. Standard configurations utilize high-quality polyamide cage material for reduced friction torque and superior heat dissipation at high operating speeds. Pre-lubricated with high-performance industrial grease and available with non-contact seals (2RS) for contaminant exclusion, this bearing minimizes maintenance requirements and guarantees operational longevity. Designed to reduce Total Cost of Ownership (TCO), the CR 11801 is the ideal solution for integrating into high-volume manufacturing equipment where space is restricted but performance cannot be sacrificed. Typical applications include small industrial motors, electric hand tools, precision instrumentation, miniature gearboxes, and conveyer rollers. The precise internal clearance (typically CN or C3) ensures optimal fitting and reduced running noise, enhancing the overall acoustic quality of the equipment. Choosing CR means investing in reduced downtime, enhanced energy efficiency, and reliable performance essential for continuous industrial processes.

Key Features

  • Optimized C3 internal clearance for superior thermal stability and misalignment tolerance.
  • Equipped with non-contact seals (2RS designation) to protect against dust and moisture ingress.
  • Precision P6 tolerance class ensures low vibration and reduced operational noise.
  • Robust 52100 steel construction for maximum load capacity and extended service life.
  • Ideal for high-speed, compact applications including servo motors and precision instruments.
