Miniature
Among the ultra-small bore miniature bearings, the types of miniature deep groove ball bearings include metric 68 series, 69 series, 60 series, etc., and there are 6 types of inch R series. On this basis, they can also be divided into ZZ steel plate dustproof Cover bearing series, miniature bearing series with RS rubber seal, bearing seal series and flanged rib series, etc.Miniature bearings refer to metric series, with an outer diameter of less than 9mm; inch series, of various types of bearings with an outer diameter of less than 9.525mm, the main materials are carbon steel, bearing steel, stainless steel, plastic, ceramics, etc., of which the minimum inner diameter can be 0.6mm, Generally, the inner diameter is more than 1mm.
Miniature bearings are suitable for all kinds of industrial equipment, small rotary motors and other fields with high speed and low noise, such as:
Office equipment, micro motors, instrumentation, laser engraving, small clocks, soft drives, pressure rotors, dental drills, hard disk motors, stepping motors, video recorder drums, toy models, computer cooling fans, money counters, fax machines and other related fields.
