1045 Pre-Keyed Precision Ground Shafting, is a 1045 steel round that has been turned, ground and polished to a 32 RMS surface finish with a pre-machined full length keyway cut to ANSI standards. Pre-keyed shafting is an economic alternative to machining shafts yourself while saving time and labor expense. Keyshafts are ideal for all projects requiring a drive shaft or rotary shaft when mating with gears, sprockets, rotary bearings and other power transmission components.
