The 12mm shaft industrial bearing is a widely used radial bearing designed for precision mechanical systems with 12-millimeter shafts. It typically features a 12-millimeter inner diameter, 32-millimeter outer diameter, and 10-millimeter overall width. The rings are made of 52100 chrome alloy steel with a surface hardness between 60 and 64 HRC. The steel balls are wear-resistant and housed in a steel or polyamide cage. This configuration provides a radial load capacity of up to 4.8 kN and an axial load capacity of up to 2.4 kN. Manufacturing accuracy complies with ISO 492 standards and P6 tolerance class.
During production, the 12mm shaft industrial bearing undergoes controlled heat treatment and precision grinding to achieve micron-level tolerances, enhancing service life. Lubrication is provided with lithium-based NLGI-2 grease or ISO VG 46 oil. The operating temperature range is from minus 20 to plus 120 degrees Celsius, with stable performance up to 150 degrees in oil lubrication. The permissible rotational speed is 24,000 rpm with grease and 32,000 rpm with oil. This bearing is suitable for electric motors, fans, gearboxes, and light industrial machinery.
