The Japanese customer contacted our engineering team with a clear application challenge. Their equipment operates continuously at a steady working speed of 7000 RPM, requiring single-side sealed 6903 LU bearing that can maintain stable rotation, low noise and reliable sealing performance under long-duration operation. The standard bearing options available on the market could not fully match their combined requirements of rotational speed, sealing structure and dimensional tolerance. Our technical team immediately carried out performance evaluation, material inspection and bench testing for the 6903 LU bearing. The 6903 LU bearing, with dimensions 17mm bore, 30mm outer diameter and 7mm width, adopts a single contact seal design to prevent dust and lubricant leakage. After repeated testing, we confirmed that the selected 6903 LU bearings can run stably at 7000 RPM under the customer’s working load without overheating or premature wear. Especially suitable small electric motors, bicycle hubs, fans, printers, power tools, precision small machinery.
