There are two carbon steel ball bearings inside the pulley, which can reduce the friction of the wheel. The pulley turns more flexibly and has no noise.
Stainless steel manufacturing, rust-proof, corrosion-resistant, outdoor use can also prevent pulley corrosion.
Compared with other pulleys, pulley wheel support plate is thicker, the wheels are stronger and the bearing capacity is stronger.
Pulleys are removable for easy installation. A single small pulley can carry 660lb/300kg
he clearance between the wheels and the frame is only about 12mm, so the rope with too large diameter cannot be passed. Generally used as a rail wheel Grooved Wheel
