NTN Ball Bearing

Ensure consistent mechanical efficiency with the NTN Ball Bearing, a single-row deep groove bearing designed for high-speed radial load applications. Featuring a 17 mm inner diameter and a 40 mm outer diameter, this NTN 6203 bearing is engineered with optimized raceway geometry to minimize friction and heat generation during high-RPM operation. Because deep groove bearings are the most widely used bearing type, they must withstand diverse stresses; NTN uses high-carbon chromium steel to prevent the premature pitting and fatigue that lead to audible vibration. Replacing a noisy or gritty bearing with this premium NTN unit restores the quiet, smooth rotation required for electric motors, pulleys, and drivetrain sub-assemblies.
