I Beam Trolley Bearing Type

  1. Nov 26, 2012 #1
    I am having trouble finding the difference between and I beam Trolley with a roller bearing and a sleeve bearing?

    I know that the roller bearing has 4 wheels that sit on the bottom base of the I Beam and roll back and forth but I am not sure how a sleeve bearing is different from that?

    Sounds like it's describing the bearings for the wheels on the I-beam roller itself, one type having a roller bearing and the other being a sleeve bearing.

    I never got to thank you for your help, but those pictures really cleared up the difference between the two bearings.

    Thank you
