Demon BB2ZZ-2 Motor Bearing 1/8 x 3/8 x 5/32. High specification. (Pair)
Very smooth with steel shields.
High tolerance with minimum slop.
Replacement bearing for many motors.
Imperial size: 1/8th inner. 3/8th outer. 5/32 width
Note: When replacing bearings, push them in by the outer edge of the bearing.
If very tight, use the old bearing to push on top of the new one.
Do not put high force on the centre as that can damage the cage which holds the balls in place.
All bearings need some light oil after cleaning.
