Clarke & Lewis UTB CL-610 Hydraulic Tube Bender

The (-10) series Precision Bending Machines feature simplicity and rugged construction.

The machine design provides capability for forming large centerline radii.

The tube/pipe is clamped directly to the bend die by a hinged clamp die. The bend die and attached clamp die rotate to form the bend. The pressure die travels with the tube/pipe during bending.

The hydraulically-actuated direct-acting pressure die is adjustable by manual control. Constant force, independent of pressure die position, tube O/D or wall variations, is applied via the direct- acting hydraulic cylinder.

The mandrel boom is adjustable for various centerline radii and is removable for storage. An outboard end support is furnished as standard.

Standard model (as shown) rotates clockwise; opposite hand rotation is available on order.

All machines are equipped with JIC cushion cylinders, JIC electrical system, hardened and ground mounting surfaces and a pressure die master bar. The pressure die master bar travels on needle bearings. Bend spindle is heat- treated alloy and rotates on tapered Timken roller bearings. All controls are located in a safe area at the rear of the machine.
