Chain Roller Turn Rollers
Special Heavy Duty
Special Heavy-Duty roller turn rollers use 5/8″ diameter balls for more load capacity than the standard roller, with a 2.95″ OD and a 3,200 lb load rating. Load ratings are based on 5,000 hours B-10 life at 33 1/3 RPM, with moderate shock, proper lubrication and maintenance, at 250°F or less.
