Quality Undercarriage Parts

These single flange bottom rollers are made to original specifications and produced with high quality double lip seals to lock dirt and debris out and lock the lubrication in for long lasting service for your machine. The flange rides down the center of your track guide to prevent de-tracking while the weight of the machine rides on the outside of the flange.
