Simple pneumatic alternative to electric rotary indexing tables

Simple pneumatic alternative to electric rotary indexing tables
Festo has launched a new generation of pneumatic rotary indexing tables that provide a flexible, cost-effective alternative to electrical models. The DHTG series rotary tables are extremely easy to install and commission, with all connections and adjusters accessible from only one side of the unit. They feature a stationary centre section with an open core for mounting electrical slip rings, rotary air distributors or additional on table automation. Flexibility has been achieved through a simple effective design that enables the direction of rotation or the number of index stations to be modified, should the application requirements change.

Electrical tables undoubtedly have their place for ultimate control over position, acceleration and speed, but they require the drives and controls of a full servo motor system. Festo has identified numerous applications where the functionality can be completely met by pneumatic systems at a lower initial cost, with far simpler controls and reduced maintenance needs. Festo's DHTG series pneumatic rotary indexing tables are ideally suited to fully or semi-automated applications, such as assembly and light machining operations.

They are initially available in  three sizes, with 90, 140 and 220mm diameter top plates, capable of generating  4.4, 18.1 and 58.9Nm of torque respectively. Each table can have 2, 4, 6, 8, 12 or 24 indexing points (stations) which can be driven clockwise, anticlockwise or toggled between the two.
