Bonfiglioli's adjustable pulley with an 11 mm bore is a compact timing-belt pulley designed for precise belt alignment and tensioning in Bonfiglioli belt-drive systems. It is used in small drive assemblies where a belt requires accurate alignment and adjustable tension, particularly in timing-belt configurations. The 11 mm bore denotes the pulley’s internal diameter, enabling installation on compatible 11 mm shafts in Bonfiglioli-compatible setups.
