Douglas Troughing Idlers
Douglas troughing idlers are sealed for life and made in the USA (Pell City, Alabama) — with sealed-for-life precision ball bearings that never need greasing, machined shouldered shafts, and rigid self-cleaning welded frames.
Available in equal and offset configurations with standard troughing angles of 20°, 35°, and 45°, plus self-aligning trainer versions for wandering belts. When a line is down, ask about emergency lead times.
