atters to be attended to use and handle
a.
Carefully insert ball bearing paying attention not to hurt inner races of bearing avoiding pushing
strongly inner ring and outer ring each other when ball bearing is inserted because scratch and dent on inner
race will give influence greatly on service life of bearing.
b.
Bearing check plate must be inserted with burr of the plate facing ball bearing side.
c.
Armature ball bearing at fan side must be inserted into housing with its open seal side coming to gear
