F16 ENGINEERING ELEMENTS AND UNITS; GENERAL MEASURES FOR PRODUCING AND MAINTAINING EFFECTIVE FUNCTIONING OF MACHINES OR INSTALLATIONS; THERMAL INSULATION IN GENERAL
Description
F16 encompasses fundamental mechanical engineering components and systems essential for machine operation and maintenance across all industrial applications. This class covers mechanical elements such as bearings, seals, gears, couplings, fasteners, and structural frameworks, along with general measures for controlling vibration, noise, and thermal effects in machinery. Also included are thermal insulation technologies, mechanical power transmission devices, and systems designed to enhance machine reliability and performance regardless of the specific industry context. The class excludes specialized components integrated into particular machines or processes, which are typically classified in their respective technical fields.
