618/7

The 618/7 deep groove ball bearing is a high-performance bearing designed for precise miniature applications. With an ultra-compact structure (inner diameter 7mm, outer diameter 14mm, width 3.5mm), it is suitable for narrow installation spaces. It is made of 440C stainless steel or GCr15 high-carbon chromium bearing steel, with a hardness of HRC 60-64. It is wear-resistant, corrosion-resistant, and structurally stable. The bearing is pre-filled with lithium-based lubricating grease upon factory assembly to ensure smooth operation and eliminate the need for initial maintenance. It also has excellent high-speed adaptability and stable dynamic and static load-bearing performance, meeting the strict requirements of industries such as precision instruments, medical devices, consumer electronics, and micro motors for space, precision, and durability. It is compatible with ISO standards and can be directly replaced with the same model from international brands. It is originally produced in China and has 118 in stock. It supports fast shipping within 48 hours and offers flexible packaging options to adapt to different purchasing scenarios.
