flexible couplings backlash - "GEB-SG"

Product catalog summary

Flexible Couplings Backlash - "GEB SG" Series

Overview

The document provides technical specifications for the "GEB SG" series of flexible couplings designed to operate without backlash. These couplings are made from aluminum and are intended for applications requiring precise torque transmission without play.

Technical Specifications

The couplings are categorized by model codes (e.g., GEB SG 9, GEB SG 14, GEB SG 19-24, etc.) with corresponding dimensional parameters. Key dimensions include minimum and maximum bore diameters, and several other critical measurements labeled as C, D, E(1), F, N, S, and L, all expressed in millimeters.

Dimensions and Parameters

Min and Max Bore Diameter (mm): Defines the range of shaft diameters the coupling can accommodate.
C, D, E(1), F, N, S, L (mm): These dimensions correspond to various coupling features such as length, diameter, and mounting dimensions. The notation E(1) indicates mounting dimensions.
Material: All couplings are made from aluminum, ensuring lightweight and corrosion resistance.

Notes and Recommendations

The dimension labeled E(1) refers specifically to mounting dimensions, which are critical for proper installation.
Material choice of aluminum provides a balance of strength and weight, suitable for precision coupling applications.

Summary

This document serves as a technical reference for selecting the appropriate "GEB SG" flexible coupling based on shaft diameter and required dimensions. It emphasizes the importance of precise measurements to ensure backlash-free operation and reliable mechanical performance.
