Generally, a rotary encoder comes as a complete unit enclosed in a stator housing with a rotating shaft. The housing mounts to the bearing stator side, while the shaft couples to the bearing rotor.

Commercial shaft encoders use magnets and Hall-effect sensors, or optical sensors and encoder discs. But these can be quite expensive, so [Hello1024] hacked together an alternative in an afternoon.
