Self-Contained Power Chuck Speeds Clamping Process, Prevents Contaminants

Schunk, Inc.'s Rota TB2 pneumatic self-contained power chuck features a new design to reduce maintenance costs and ensure process reliability. Despite the compact outer dimensions, the Rota TB2 has a large through-hole ranging to 560 mm. With an air pressure of 6 bar, it is possible to achieve high clamping forces of up to 280 kN.

Base-jaw guidance is equipped with a special seal to prevent penetration of contaminants, helping reduce maintenance costs. The design of the base jaws has 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 maximum process reliability.

To increase the cycle rate when machining pipes and rods, the Rota TB2 features a double-acting check valve with extra-large channel bores, speeding up the clamping process. Upon completion, the quick-action ventilation system releases the clamping setup.

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