61815 Bearing Structural Features & Performance Benefits
The performance of the 61815 bearing is derived from its robust construction and high-quality materials. The single row deep groove raceways are precision-ground to facilitate smooth operation and efficient radial load carrying. The use of a stainless steel cage provides excellent durability and corrosion resistance, contributing to stable performance at the high limiting speed of 8,500 rpm. The open design, combined with the P6 tolerance, ensures minimal vibration and heat generation, which is critical for high-speed applications. With a radial dynamic load rating of 2810 lbf and a static load rating of 2428 lbf, it offers reliable performance under significant stress. The chrome steel rings and balls provide high hardness and wear resistance, ensuring a long operational life.
