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."
[ ! ]About Hollow Shaft Wall Thickness Deviations, please see >> P.111
[ ! ]Features of Low Temp. Black Chrome Plating
>>P.128
[ ! ]Circularity and O.D. tolerance may not meet precision specification in areas approximately 15mm from wrench flats machined ends.
[ ! ]Circularity, Straightness, Perpendicularity and Changes in Hardness >>P.111
[ ! ]Low temp. black chrome plating is not applied to the inside of hollow shafts, taps, bored holes and lateral holes, and may rust.
[ ! ]Annealing required for wrench flats machining and shaft end threading (effective thread length + approx. 10mm) may lower hardness. >>P.112
