28BYJ-48 Outboard Bearing Drive Bracket
Bracket that bolts a 28BYJ-48 geared stepper (35 mm ear spacing, 5 mm flatted shaft offset 8 mm from the body) to a vertical plate and carries a 625 bearing (16 mm press pocket) in a second upright 50 mm away, so a 5 mm steel output shaft takes the side load instead of the motor's thin shaft. A 30 mm snap-off coupler with two 5.3 mm bores and M3 self-tap set screws joins the motor flat to the output shaft; the ear slots are 4.5 x 7.5 mm so the motor slides until the coupler spins freely. Base 80 x 44 x 4 mm with four M3 holes at 62 x 26 mm.
