Made in a pinch in TinkerCad because I needed something to pull a worn 6201 bearing off of the shaft of my washing machine motor.
Intended for type 6201 rolling bearings: 12 x 32 x 10mm (ID x OD x Width). May fit some smaller dimensions as well.
Uses an M8 hex nut and corresponding hex bolt (I recommend using a slightly longer bolt than the one in the photos, that was all I had at the time).
The inside hight of the puller is 25mm. Fits around shafts up to 18 mm diameter and requires at least 7 mm of clearance below the bearing. I used the max space available to me between the commutator and the bearing to optimize for strength.
The 8 mm through hole is a little on the tight side but its manageable.
Printing
I used generic PLA with 6 wall loops und 20% rectilinear infill for extra strength.
Print on the rectangular flat side. Two small supports for the hex nut recess and through hole are recommended.
