How can you tell if a motor has sleeve bearings or ball bearings?

    take it apart - or read the nameplate --it will be listed as to what type of bearings -why ?

    bearings

    I don't recall seeing the type of bearings on the motor name plate.And taking apart a good motor doesn't seem logical. I am using an ICM head pressure controller which varies the motor speed.There are two differant settings,one for sleeve bearings and the other for ball bearings.
