GATES BX 81 Deep Groove Ball Bearing | 40x80x18mm High-Speed Industrial DGBB

The GATES BX 81 Deep Groove Ball Bearing is engineered for demanding industrial power transmission applications, offering exceptional performance and reliability. Featuring a standard 40mm bore (d), 80mm outer diameter (D), and 18mm width (B), this bearing utilizes high-carbon chromium steel (SAE 52100) and precision-honed raceways to minimize friction and ensure optimal load distribution. Designed to meet or exceed ABEC P5 precision standards, the BX 81 offers superior running accuracy crucial for high-speed operation and reduced vibration in sensitive machinery. Its robust construction provides high dynamic and static load ratings, making it suitable for continuous, heavy-duty cycles in diverse operating environments. Selecting the GATES BX 81 ensures minimal downtime and extended service intervals across critical machinery such as electric motors, conveyor systems, industrial pumps, and gearboxes. Its versatility and established reliability are core to reducing total cost of ownership (TCO) for maintenance operations. The BX 81 is designed for easy installation and compatibility with standard industrial shafts and housings, providing a durable solution that resists common operational stressors like misalignment and contamination. Trust GATES engineering for bearings that deliver consistent, maintenance-friendly performance under the toughest conditions.
