Check the listing for details. Atlas Craftsman 10" 12" Spacer Change Gear Bushing 9-70A (QTY 3) Higher Quality. Condition: New. Listed at 12.00 USD. Description:Selecting a quantity on one (1) includes three (3) keyed spacer bushings for change gears on 10" and 12" Atlas lathes. For "A" series gears with 3/4" double keyed center hole and 1/2" wide. Each bushing is 1" long with 1/2" center arbor hole. Each is hand fitted onto an original arbor and into an original gear to insure a quality fit. Higher quality than others you will find. These are 3D printed in PETG (not the much more common PLA). PETG is a higher quality plastic than PLA. It is tougher, more durable, and stronger. It also has better chemical resistance to oils and greases. It is also stiffer than nylon which has a tendency to stretch and slip instead of breaking. This is important if you have a crash and are using original gears as the nylon could turn in the gear hole and potentially crack it. These should give years of normal service but if you ever have a problem with one you have my personal replacement guarantee. (Includes 3 spacers - DOES NOT include the gear or arbor in the picture, They are for demonstration only.)
