Standard bearings refer to bearings that do not meet the external dimensions specified in national standards, and their specifications, structures, or tolerance systems differ from the GB/T 273 series standards. This product needs to be customized according to customer drawings and has the characteristics of low universality, small batch manufacturing, high cost, etc. It is commonly used in special equipment such as aerospace, high-speed railways, precision instruments, and complex working conditions. This type of bearing adopts personalized design, with adjustable structural parameters such as the number of steel balls and roller arrangement. The materials cover special types such as titanium alloy, ceramics, stainless steel, etc. to meet the requirements of corrosion resistance and high temperature resistance. Typical models include S695ZZ anti magnetic bearings, 2.5x5x1mm micro deep groove ball bearings, etc., which are used in fields such as clock movements and medical equipment. Daily maintenance requires surface treatment through solvent cleaning and compressed air blowing, and the use of immersion or spraying anti rust oil processes to delay rusting.
