12t x 9mm Wide Double Flange Aluminum Pulley (GT2 3mm, RS550 Motor)

Synchronous timing belts and pulleys are lighter and can be more efficient than chains and sprockets. Once set up, they require no tensioning or adjustment. These pulleys go hand in hand with GT2 timing belts, and are great for low-load applications.
