The B&B SUMNER Power Roller Idler is a durable and efficient support system engineered to complement powered roller setups in industrial pipe and vessel fabrication. Designed to work in tandem with drive rollers such as the 3810 Mega power roller driver and standard welding rotators, this idler unit ensures steady, balanced support for rotating cylindrical components during welding, fabrication, and inspection tasks.
Capable of supporting a substantial load of up to 4 tons / 8,000 lbs per driver and idler set, the 3812 provides the strength and stability required for medium to large vessel applications. It offers tractive pull of up to 1,000 lbs and a maximum wheel torque of 2,000 in-lbs when used with its powered counterpart, enabling smooth and consistent vessel rotation.
The idler is compatible with vessels ranging from 3 – 48″ / 76 – 1,219 mm in diameter, making it highly versatile for various industrial settings. It supports rotation speeds between 8 – 80 in/min / 203 – 2,032 mm/min, allowing for process customization based on job requirements. Its height adjustability from 28 – 40″ / 711 – 1,016 mm provides ergonomic flexibility and efficient alignment with other shop equipment.
