Schunk's Rota TB2 is a pneumatic self-contained power chuck for machining rods and pipesClick image to enlarge

The SCHUNK Rota TB2 pneumatic self-contained power chuck sets a new standard in the machining of rods and pipes for the oil, mining, and construction sectors, claims the company.

Despite the compact outer dimensions, the Robta TB2 has a large through hole of up to 560 mm. With an air pressure of 6 bar it is possible to achieve high clamping forces of up to 280 kN. The base jaw guidance is equipped with a special seal to prevent penetration of contamination, which helps reduce maintenance costs.

The design of the base jaws have been optimized for minimal loss of centrifugal force even at high rotational speeds. An advanced lubrication system ensures constant clamping forces and an optional integrated pressure sensor provides for maximum process reliability.

To increase the cycle rate in the machining of pipes and rods, the new chuck features a double acting check valve with extra large channel bores, which speeds up the clamping process. After completion of machining, the quick action ventilation system releases the clamping setup.

The TB2 is available in sizes from 470 mm to 1,000 mm with bore diameters from 185 mm to 560 mm.
