The NTN 6003 ZZCM/5K is a precision-engineered single-row deep groove ball bearing designed for high-speed and low-friction rotational applications in industrial machinery, motors, pumps, conveyors, and automation equipment. Manufactured using high-carbon chromium bearing steel, the bearing features double metal shields (ZZ) for protection against dust and contamination while retaining lubrication for extended service life. The CM internal clearance configuration provides optimized running accuracy and reduced vibration in electric motor applications. Pre-lubricated with NTN 5K grease, the bearing supports reliable operation at speeds up to 20,000 RPM under grease lubrication conditions. Its compact 17×35×10 mm dimensions and durable construction make it suitable for industrial rotating systems requiring stable performance, low noise, and long operational life.
