CR 6818 Deep Groove Ball Bearing (90x115x13mm) - Extra Light Series High Precision
The CR 6818 Deep Groove Ball Bearing is engineered for applications demanding exceptional precision and minimal radial space, conforming strictly to ISO standards for the extra light 6800 series. Featuring a robust design with high-quality hardened steel races and a precision-machined cage, this bearing ensures optimal alignment and reduced rotational friction across a wide range of operating speeds. Its defining characteristics are the 90 mm bore and a very narrow 13 mm width, providing a solution where standard width bearings are infeasible. The 6818 series maintains a superior dynamic load rating (Cr) optimized for moderate radial loads despite its slim profile, guaranteeing reliability and sustained performance in demanding industrial environments.
Ideal for compact electric motors, specialized textile machinery, precision pumps, and robotic joints, the CR 6818 bearing delivers efficiency and longevity. The tight internal clearances and high-grade surface finish minimize vibration and noise, crucial for sensitive equipment. As a Senior Product Manager, we recommend this bearing for customers seeking to reduce equipment footprint and energy consumption without compromising on load capacity or operational lifespan. CR’s commitment to material science ensures reduced maintenance intervals and significantly lower total cost of ownership (TCO) compared to standard commercial alternatives.
