Products Feathures:
Among the miniature bearings with ultra small apertures, there are six types of miniature deep groove ball bearings, including the metric 68 series, 69 series, 60 series, etc., and the Inch R series. Based on this, they can also be divided into the bearing series with ZZ steel plate dust cover, the RS rubber sealing ring micro bearing series, the Teflon bearing sealing ring series, and the flange series, etc.
It can be used for parts that rotate at high speed with low friction torque and for all applications that require low noise and low vibration.
Working Temperature Range: -25 to 120°C

FAQ：
1.What is miniature ball bearing?
Miniature: small sized ball bearings
Ball bearings are machinery components, and they comprise an outer ring, inner ring, balls, retainers, shields and snap rings. Miniature or small-sized ball bearing mean ball bearing, up to 30mm in external diameter. Ball bearings determine rotational accuracy for high precision rotary components.
2.What is the minimum size of a ball bearing?
Small diameter ball bearings with a bearing outer diameter of less than 9 mm and inner diameter of less than 10 mm,which are suitable for high speed rotation.
Applicable Industries: high speed and low noise fields, such as office equipment, micro motors, instrument instruments, laser engraving, small clocks, soft drives, pressure rotors, dental drills, hard disk motors, stepper motors, VCR drums, toy models, computer cooling fans, currency counters, fax machines, and other related fields.
