Introduction of miniature bearings
Miniature ball bearings are metric series, outer diameter less than 9mm; inch series, outer diameter less than 9.525mm of all kinds of bearings! The primary materials are carbon steel, bearing steel, stainless steel, plastic, ceramic, etc. The minor inner diameter can be 0.6mm, the general inner diameter of 1mm more.
In the ultra-small bearings, miniature deep groove ball bearing types are metric 68 series, 69 series, 60 series, etc., the British system R series, a total of six kids, on this basis, can also be divided into ZZ steel plate dust cover bearing series, with RS rubber seal miniature bearing series, Teflon bearing seal series, with flange retaining edge series, etc.
Miniature bearings are suitable for various types of industrial equipment, small rotary motors and other high speed and low noise fields. Such as office equipment, tiny engines, instrumentation, laser engraving, small clocks and watches, soft drives, pressure rotors, dental drills, complex disk motors, stepper motors, VCR magnetic drums, toy models, computer cooling fans, money counting machines, fax machines and other related fields.
