70 SeriesFeatures: The two sides are equipped with non-contact sealing ring, the selection of large steel ball, so that the bearing has a large rigidity, bearing capacity.
a, 70 series, contact angle c:15°,ac:25°
b, Cage: outer ring Guide phenolic resin cage (unmarked)
c, rolling body: Steel ball (no mark), Ceramic ball (HQ1)
d, as the internal and external rings are single stall edge, increasing the internal space of bearings, is conducive to the storage of more lubricants, improve the lubrication performance of bearings, prolong the service life of bearings.
* Use ceramic ball to obtain higher speed, higher life
