Problem:
Wear of Plug Door Tracks by Metal Rollers
Constant vibration causes metal rollers to wear through plug door tracks, resulting in costly weld repairs. In extreme cases, the metal roller can break through the track, causing the door to disengage resulting in a serious worker safety hazard. In addition, uneven roller wear degrades the operation of the box car door, making it more difficult to open and close.
Solution:
Self-Lubricating Plug Door Guide
The large bearing surface of the Pennsy Polymer Guide protects the track from concentrated loading. The low friction material enhances door operation and eliminates the problems of weld repairs and door disengagement. For additional safety, Pennsy has embedded a metal insert in the polymer guide. The self-lubricating material combined with a coated steel pin provides smooth, corrosion free operation.
