CR 61818 Thin Section Deep Groove Ball Bearing (90x110x10mm) | High Precision & Speed
The CR 61818 Deep Groove Ball Bearing is engineered specifically for applications where strict weight constraints and limited radial space are critical. As part of the 61800 thin section series, this bearing features a minimal cross-sectional area (90mm bore, 110mm outer diameter, 10mm width), enabling dramatic reductions in machine size and mass without significant compromise to load-carrying capacity. Manufactured from high-carbon chromium steel (AISI 52100 equivalent), the 61818 offers exceptional rotational precision, reduced friction, and superior fatigue life, ensuring reliable performance in demanding industrial environments.
Optimized for high-speed operation and low running torque, the CR 61818 is the ideal choice for instrument drives, robotics, aerospace mechanisms, and precision medical equipment. CR's proprietary manufacturing processes ensure tight tolerance controls (P6 grade standard or better), minimizing vibration and extending maintenance intervals. By selecting the CR 61818, engineers can achieve significant power savings and improved dynamic response in compact systems, guaranteeing long-term operational efficiency and a lower Total Cost of Ownership (TCO) compared to standard-series bearings.
