    It depends. If it is an "adjustable" type of bottom bracket, then you can replace just the spindle. If it is a "cartridge bearing" type of bottom bracket, you have to purchase a complete bottom bracket.

    Check out :http://www.parktool.com/repair/byreg...mageField2.y=6
    for service instructions for both type of bottom brackets.

    I think you may be looking for a bottom bracket (spindle + cups + bearings) that screws into the bottom bracket shell on your frame. You can find these at any LBS and most likely one that will work for your bike and crankset.
