B 38 Precision Deep Groove Ball Bearing (38x62x17mm) | High-Speed Industrial Machinery
The B 38 High-Performance Industrial Bearing is engineered for critical applications demanding exceptional rotational accuracy and load handling within constrained spaces. Constructed from high-purity, vacuum-degassed bearing steel (SAE 52100 equivalent), this deep groove ball bearing features optimized raceway geometry to minimize friction and thermal buildup, ensuring prolonged operational life even under continuous duty cycles. With a tight P6 tolerance class, the B 38 is ideally suited for electric motors, gearboxes, industrial pumps, and conveyor systems where precision alignment and reliable performance are non-negotiable.
Designed by GATES, a trusted leader in power transmission components, the B 38 bearing significantly reduces the total cost of ownership (TCO) through superior durability and extended lubrication intervals. The robust pressed steel cage maintains ball separation integrity during rapid acceleration and high-speed operation (up to 14,000 RPM limiting speed). Its sealed-for-life design (if applicable, or high-performance open structure) ensures protection against particulate contamination and moisture ingress, resulting in fewer unplanned maintenance stops and maximizing equipment uptime in harsh factory environments.
