SINO BEARINGSJul 28, 2022

Micro bearing refers to the metric series, the outer diameter is less than 9mm; Inch series, the outside diameter of all kinds of bearings less than 9.525mm! The main materials are carbon steel, bearing steel, stainless steel, plastic, ceramic, etc., of which the minimum inner diameter can be 0.6mm, the general inner diameter is 1mm more.

In ultra small aperture in the miniature bearing, miniature deep groove ball bearing type has the metric 68 series, 69 series, 60 series, etc., inch on a total of 6 R series, based on this, also can be divided into with ZZ steel dust cover bearing series, rubber sealing ring with RS miniature bearing series, teflon bearings seals series and flanged penal series and so on。

Micro bearings are suitable for all kinds of industrial equipment, small rotary motor and other fields with high speed and low noise, such as:

Office EQUIPMENT, MICRO MOTOR, INSTRUMENT, LASER ENGRAVING, SMALL WATCH, SOFT driver, PRESSURE rotor, dental drill, HARD disk motor, STEpper motor, VIDEO drum, toy model, computer cooling fan, money counting machine, fax machine and other related fields.
