UHMW or steel? UHMW is quieter, will not corrode and is easier on the track, but it is rated to 750 lb per gate. Above that, or on a high-cycle commercial gate, go to steel — see the 6 in. 1201-000. For a lighter duty sleeve-bearing version rated to 500 lb, see the 1201-004.
When to replace them. Worn wheels or seized bearings are the usual cause of a sliding gate that grinds, judders or drags as it travels, and of a gate that sits low at one end. Replace wheels in pairs so the gate stays level and the load stays even.
What else you may need. This is the wheel alone. If the brackets are rusted through or you are hanging a new gate, add V-wheel mounting plates. For the full range of wheels, guide rollers, catches and drive chain, see sliding gate hardware.
