Example of Stacking
This section provides an example of stacking configurations for the LGU146-MEF20 and MFF20 models. It includes details on dimensions, output torque curves, and weight specifications.

Dimensions
The document outlines the dimensions for the unit type φ146 with a maximum output torque of 540 Nm. Specific models such as LGU146-3MEF20, LGU146-4MEF20, and LGU146-5MEF20 are mentioned with their respective weights and spline hole dimensions.

Output Torque Curve
The output torque curve is illustrated, showing the relationship between output torque (Nm) and output revolution (rpm) for the LGU146-M20 series. The graph indicates torque values up to 540 Nm.

Unit Type Combination
This section describes the combination of unit types for multi-stage configurations. It lists the first and second stage model names, actual speed ratios, and optional parts such as joint shafts and spacers.

Multi-Stage Usage and Optional Parts
References are made to pages 31 and 32 for further details on multi-stage usage and optional parts. It is noted that units will not be stacked at shipment.

Additional Notes
To secure the joint shaft axially, two C-rings (JIS B 2804) STW-16 are required, which are not included in the optional parts.
