Rotary Indexer - IR Series

The IR Series rotary indexer is designed for precise rotary indexing applications. It features a compact design with short axial dimensions and a wide platform. A robust cross roller bearing balances unbalanced radial and axial loads effectively. The gearbox includes a hollow through-portion at the center for flexible installation. Motor connection is on a parallel axis relative to the output shaft supported on the bearing.
