SIST ISO 155:1999 sets international guidelines for belt drives by specifying the limiting values for the adjustment of centre distances between two transmission pulleys. This standard applies to various pulley designs used in mechanical power transmission, including flat belt pulleys, V-belt pulleys, V-ribbed belt pulleys, and synchronous belt pulleys. By recommending consistent adjustment limits, the standard supports optimal performance, reliability, and safety in belt-driven power transmission systems.
