Bearing show: F688ZZ Size 8*16*5mm small size metric flange bearings super high precision ball bearing
Ⅰ. About Extra-miniature, miniature and small ball bearings of this type have flanges on their outer rings to make positioning
in the axial direction easy, and they achieve economy by
eliminating the need to spotface the housing edges.
This type is ideal for parts that require high-speed rotation,
low-friction torque and low-vibration/noise for devices that should
be smaller, thinner and lighter-weight..
Ⅱ. Feature : Advantage MF684ZZ flanged ball bearings with a flange on the outer, axial positioning easy.no need bearing block, become more economical. flanged ball bearings is suitable for low-friction bearing torque, high rigidity, good rotation accuracy condotion.
Ⅲ. Application: Miniature Flanged ball bearings is use in small motor, R/C toys,
micro engine, R/C cars, RC Aircraft, Radio Control,RC Slot car and
mini fan, etc.

Based on reliable quality , Daiwa has got great achievement in the field of high rotating speed, and cooperated with several aeromodelling motor companies to develop good ball bearing with high speed,low noise,long life features. Advantages in the manufacturing process gradually formed and started to take a fixed market share. Shared a very big market in excess of 70% for miniature ball bearing domestically. Especially in aeromodelling market ,we are taking 80% market share .
