SIT TORQUE-FLEX® Classic High-Performance Belts are manufactured in accordance with European standards ISO 4184 and DIN 2215. Designed for high-speed operation on small-diameter pulleys and short center distances, they are also suitable for use in multiple V-belt drives where high shock loads and heavy loads are encountered. No special selection is required for multiple drives, as they are manufactured according to the Matchmaker® System, which ensures better production tolerances compared to regulatory limits.
