A pulley is a wheel on an axle or shaft that is designed to support movement and change of direction of a taut cable. The supporting shells are called blocks.
A pulley may also be called a sheave or drum and may have a groove or grooves between two flanges around its circumference. The drive element of a pulley system can be a rope, cable, belt, or chain that runs over the pulley inside the groove or grooves.
QFAP has specialized in producing various kinds of pulleys more than 10 years, could help to design or produce the pulley according to your requirements. (OEM accepted)
