What the AI looks for in Industrial Drive Belt & Chain Tensioners

Placement on the slack side: Mount the idler or tensioner on the slack span, never on the tight side. A tensioner on the tight side adds load to the belt and bearings and shortens the life of both.
Inside vs backside idler: Inside idlers on timing and V-belt drives should be grooved or toothed to match the belt. Backside idlers should be flat. A wrong idler face damages teeth or sidewalls and reduces wrap on the small pulley.
Minimum idler diameter: Keep the idler at or above the belt maker's minimum pulley diameter for that belt section. Undersized idlers over-flex the belt and crack the cords.
Chain engagement: Chain idler sprockets should engage several teeth and match the chain pitch and strand count. Too few teeth in mesh causes jumping and rapid sprocket wear.
Fixed vs automatic: Use spring or elastomer automatic tensioners where belts stretch or loads pulse. Use fixed adjustable idlers where precise set tension is required. Automatic units compensate for wear, but they can let synchronous drives ratchet under shock loads.
