The output has a flange for an indexing table, and another hollow table mounting flange for processing units. The internal mechanism is similar to the DA Type but instead of the continuous drive shaft, the table mounting flange is stationary and hollow to allow wiring and air lines to be stored for easier maintenance and servicing.
Double Coaxial Output Design
Features a coaxial output with indexing shaft and hollow stationary shaft. Ideal for driving rotary base assembly machines.
High Accuracy
The intermittent indexing motion is produced by a roller gear cam for precision positioning.
Typical Applications
  • Assembly and inspection machines for automotive components
  • Assembly and inspection machines for electronic components
  • Use as base chassis or main drive unit for various automated machines.
