Gravity roller conveyor gets the job done, without fail, because gravity never stops working for you. Tongue-in-cheek aside, gravity conveyors are durable and simple to use. Perfect for accumulating at the end of a powered conveyor section or queuing boxes for shipping. These extreme-duty gravity conveyors feature 3.5″ diameter x 9 ga uncoated steel rollers and structural steel frames.
3-1/2″ x 9 gauge steel tubing, with straight ends, reamed to provide smooth bearing seats
4″ at 5.4 lbs structural steel painted channel for rollers set high, 5″ at 6.7 lbs structural steel painted channel set low (extra charge for set low). All frames have butt type couplings.
11/16″ hex shaft, spring loaded
Available in 1′-0″ increments from 1′-0″ to 10′-0″
Precision ABEC bearings
700 lbs per roller or 3,750 lbs maximum distributed live load per 10′ section with supports at 10′ centers; 8,000 lbs with supports at 5′ centers
To prevent pinch points that exist when gravity conveyors are permanently attached to power conveyors, use connector brackets with safety pop-out rollers.
