Overview
The document provides technical specifications and details for AKIM's Swiss-made cycloid reducers, specifically models 2S-50 to 2S-120 in the plug-in version. These reducers are designed for applications requiring high power, high torque, and significant reduction ratios.

Specifications
- Reduction Ratios: Single-stage ratios range from 18:1 to 125:1, with integer and mathematically precise values. Ratios greater than 125:1 require a two-stage reducer.
- Drive Speed: Up to 1500 min^-1 permissible.
- Backlash: Low backlash with fixed settings depending on the application, adjustable from outside, and less than 0.02°.
- Efficiency: Achieves rates well over 90%.
- Nominal Torque: Up to 20,000 Nm.
- Design: Easy motor mounting with a separate flange and coupling, conventional motor compatibility, high overload safety, robust design, and maintenance-free with lifetime lubrication.

Technical Data
The document includes detailed tables of reduction ratios and admissible continuous torque for each model (2S-50 to 2S-120) at various drive speeds (1500, 1000, 750, and 500 min^-1).

Dimensions
Dimensions for each model are provided, including input and output dimensions, lantern mounting dimensions, and specific measurements for various IEC standards.

Key Features
- High power and torque capabilities.
- Short mounting length due to the hollow shaft design.
- Excellent weight/performance ratio.
- Reliable and robust construction.
