Miniature Ball Bearings 1*3*1mm 681 681 ZZ Miniature Deep Groove
Ball Bearings For Roller Skating Fingerboards
Description: of Deep Groove Ball Bearing 681
The miniature deep groove ball bearing is installed on the shaft,
within the axial clearance range of the bearing, it can limit the
axial displacement of the shaft or housing in two directions, so it
can be positioned axially in two directions. In addition, this kind
of bearing also has a certain self-aligning ability. When the
bearing is inclined 2'~10' relative to the shell hole, it can still
work normally, but it will have a certain impact on the bearing
life.
Miniature stainless steel bearing materials mainly include 420,
440, 304, 316
