  • ? on bearings in elec motor

    Among the specs for a 1/2 HP motor are ball bearings, DE bearing:none, OPE bearing:none.

    What the heck are DE and OPE bearings??

    DE is for "Driven End", that's the end with the output shaft.

    OPE is for "Opposite Pulley" end, and that's for the other end of the motor.

      So---that motor has no bearings?
      I seldom do anything within the scope of logical reason and calculated cost/benefit, etc- I'm following my passion-

        Not "Ball Bearings". It probably uses bushings.

          Hi There,

          I think the "correct" term is Sleeve Bearings.

            It may have bronze bushings, cheap and easy to replace.

              Some of the older motors have a bronze bushing spherical bearing on the back side (OPE). These are non-serviceable and non-replaceable, as far as I can tell. You can add a few drops of oil to the felt wick that surrounds the bushing but there is nothing more you can do.

              I'll rephrase that -- if you try to do more, like drive out or press out the spherical bearing it will shatter. If you know where replacements can be obtained, let me know.
