Look for Tonegawa Seiko Servos
SSPS-050 and SSPS-105 (world's strongest RC servos)

    Thank you, I will look into it...My concern with a DC motor is overheating
    it while making it go forward and reverse in a short period of time. Like a
    3 sec cycle time while traveling up to 2 feet in either direction...

    Has anyone found a place where you can buy bigger, larger Voltage
    servos with more weight/torque and speed than the ones that we all
    use for out remote control projects? I would like to find some that
    have the same logic to them, because that is what we all know using
    (pulsout commands) but can operate in an industrial enviroment as a
    Pic-N-Place application. Thank you in advance!

    How BIG? Real BIG or only a little bit BIG? VBG

    When I bought the servos for my HO scale rotary dumper
    http://www.ida.net/users/tetonsl/railroad/dumper.htm at the local hobby
    shop, they catalogued Expert Brand model SL820, 2.48" x 1.26" x 2.46" with
    214 oz/in torque. Didn't stock them of course. Still work at 5 volts.

    Different interface technique (step and direction signals) but look at the
    G320 from www.geckodrive.com It is a control package that allows you to use
    any brushed DC motor from 24 V to 80 V and up to 20 amps. Definitely an
    industrial class solution and pretty reasonable at $99 each. You still need
    to get a motor with an encoder, but you can pick them up on E-bay for $10 -
    $50 depending upon how big you need.

    Just have to use a motor that is sized large enough to handle the
    acceleration without needing to keep it at the peak torque for the whole
    travel. Also, air and water cooling are not unheard of in an industrial
    setting. I am using a set of these drives on my CNC machine and they are
    working out great.

    go to www.towerhobbies.com, it has a lot of servos, including high
    torque, high speed, ball bearing, etc etc
