Timing Pulleys & Idlers（Type：Idlers）

Timing Pulleys and Idlers are toothed gears that mesh with a belt rather than each other. They are lubrication-free, corrosion-resistant, and have reduced noise and cost impact when compared to traditional chain and sprocket mechanisms. There are many tooth profiles to handle a variety of applications. Trapezoidal profiles like "L," "T," and "AT" are great for conveyance, where the belt will be running for hours continuously. Curvilinear profiles like "S#M," "GT," and "EV" are ideal for high-torque positioning applications where the belt will need to change directions often and require low backlash.
