The NACHI industrial bearing model 6806 is a single-row deep groove ball bearing with a thin-section, high-precision design suited for high-speed and compact applications. It features a 30-millimeter inner diameter, 42-millimeter outer diameter, and a 7-millimeter width. The balls are made from chrome alloy steel with a hardness of 60 to 64 HRC, and the rings are manufactured from SUJ2 bearing steel. Dimensional accuracy complies with ISO 492 standards and tolerance class P6. The optimized point contact geometry reduces friction by up to 30 percent and ensures operational stability at high rotational speeds. The thin profile minimizes weight and enhances energy efficiency in rotating systems.
Production of the NACHI 6806 bearing involves ultra-precision grinding and multi-stage heat treatment to improve fatigue resistance and surface uniformity. It operates within a temperature range of minus 20 to plus 120 degrees Celsius, and up to 150 degrees with polyalphaolefin-based grease. Lubrication is provided by NLGI-2 grease or ISO VG 32 oil. The maximum speed rating is 15,000 rpm with grease and 23,000 rpm with oil. This model is widely used in electric motors, medical devices, precision instruments, and light industrial machinery.
