NBJX = 400mm x 500mm or 15" x 20" SUPER HEAVY DUTY ROLL LATHE JAWS UP TO 100 TONS Capacity for Roll Turning & Deep Hole Drilling Applications
These Jaws are used to aggressively clamp items such as large rolls on the large lathe for turning.
Those rolls often weigh in excess of 80~100 Metric Tons.
Our "HEAVY DUTY JAWS" are different from conventional jaws only by its screw rods- their screw rods are a mechanical-force-boosting screw rods type.
The other apsects of these jaws are the same to those on the conventional jaws.
The jaws exert large clamping forces to heavy workpieces like rolls, large shafts etc., weighing tens of tons,
by driving the jaws' screw rods with a small torque manually.
Large & heavy workpieces will not slip on the serrated faces of the jaws after clamping.
THE FASTER THE WORKPIECE SPINS, THE TIGHTER THE JAW GRIPS BY CENTRIFICAL FORCE.
The approximate overall length of this jaw is 20" / 550mm
The approximate overall width of this jaw is 15" / 400mm
