1. Product Description and Series

The RGIS 025 belongs to the oscillator index series, designed for precise angular positioning with multiple dwell options. The series includes small type units with straight shafts and various cam unit options such as flat standard, parallel cam, roller gear cam, and small multi-index wide angle units.

2. Dimensional Specifications

Dimensions are provided in millimeters, covering input and output shaft sizes, shaft intervals, and mounting details. Key dimensions include shaft diameters (e.g., ø4, ø8h7, ø10h6), shaft intervals, and mounting hole specifications (e.g., 5 x 4-M4 depth 7). The document includes detailed shaft and body measurements to ensure compatibility with mechanical assemblies.

3. Indexing and Oscillation Parameters

The unit supports multiple dwell configurations: 1, 2, 3, and 4 dwells, with corresponding total index angles ranging from ±90° to ±300°. Oscillating angles and index numbers are tabulated, allowing selection based on application requirements. The total index angle (t) and oscillating angle ( ) are critical for defining the motion range.

4. Performance Characteristics
