Rex / Tsubaki questions
My elevator chain keeps stretching — chain quality or sprockets?
Both, usually: worn sprocket teeth hook and yank the chain, accelerating pin wear ('stretch'). New chain on hooked sprockets dies in months — the classic maintenance false economy. Measure sprocket tooth profile whenever elongation passes 2%. We match complete sets. Call (641) 519-6270 for a free teardown quote — or sell us the unit as-is for cash.
