Pneumatic rotary indexing table GT series

verticalfor machine toolsfor heavy loads

Description
The Kitagawa GT-200 rotary table is a through‑hole indexing unit engineered for heavy cutting loads. It features a 200 mm diameter table, a 45 mm spindle through hole and provides up to 41.6 rpm spindle speed for high‑speed indexing. The rigid body design minimises deformation under load and the pneumatic clamping system delivers 820 N·m at 0.5 MPa.
