MISUMI
"[Features] This shaft facilitates customers to arrange wiring, because the wire can be pierced into the inside of the shaft and contributes to weight saving of equipment, because the shaft is hollow."
[ ! ]Features of Low Temp. Black Chrome Plating >>P.128
[ ! ]Low temp. black chrome plating is not applied to the inside of hollow shafts, taps, bored holes and lateral holes, and may rust.
[ ! ]Circularity, Straightness, Perpendicularity and Changes in Hardness >>P.111
[ ! ]Annealing may lower hardness at shaft end machined areas (effective thread length + approx. 10mm).
