    These pulleys spin freely on built-in bearings to maintain tension for reduced wear and vibration. They’re often used with belt tensioners (sold separately).
    Ball Bearing—Pulleys with ball bearings ensure proper positioning inside a tube or housing. They’re sealed to block out dust and contaminants better than pulleys with needle roller bearings.
    Needle Roller Bearing—Pulleys with needle roller bearings minimize internal friction.
    Nylon—Nylon pulleys are lightweight and corrosion resistant.
    Cast Iron and Steel—Cast iron and steel pulleys are more durable than nylon pulleys.
