Friction Testing Machines for Bolted Connections

Product catalog summary

Overview: The document provides detailed information about friction testing machines for bolted connections manufactured by TesT GmbH. These machines are equipped with patented multi-component sensors and are designed to meet both national and international standards. They are used to measure forces, torques, and angles to determine friction coefficients in screws, bolts, nuts, and components, ensuring optimized and safe fixation.

Specifications: The document lists various models of friction testing machines, detailing their dimensions and weights. Models range from table-top to steel frame types, with varying capacities and sizes to accommodate different testing needs.

Multi-Component Sensors: The patented sensors allow for the decoupled measurement of tension force and torque within screws. These sensors are crucial for applications in the automotive industry, fastener manufacturing, and large-scale mechanical constructions, including wind power stations.

Sensor Selection: The document provides a detailed table of sensor sizes and their corresponding strength classes, indicating the range of forces and torques they can measure. This information is critical for selecting the appropriate sensor for specific testing requirements.

Measurement Principles and Uncertainty: The document outlines the measurement principles using Wheatstone Bridges and specifies the measurement uncertainty, which is within ±0.5% of the nominal value for each channel.

Applications: The friction testing machines are primarily used in laboratories for research and development, quality control, and various industrial applications, with recommended operating temperatures between +15°C and +30°C.

Technical Changes: The document notes that technical specifications are subject to change, indicating the dynamic nature of product development and improvement.
