Shaft Bore Dia. 6.35 is available for Straight Bore and Straight Bore + Tap. Specify 10K as P dimension if keyway width of 4.0mm (height 1.8mm) for Keyway + Tap with shaft bore diameter of 10 is desired. >> P.1498
Shaft Bore Dia. 9 is not available for Keyway + Tap. Combine the same handedness (L and L or R and R) for unparallel shafts and different handedness (L and R) for parallel shafts.
Helical gears generate axial thrust on shafts. Choose bearings that can withstand the axial thrust generated by the gears.
