 Plastic Educational Pulleys

Pulley systems and individual plastic pulleys with metal frames are used in teaching about pulleys in physics and mechanics education. Most plastic pulleys come in a steel frame; however, we are also offering some that have aluminum frames. Pulleys with aluminum frames are recommended for experiments in which you may have a strong magnet in the path of a pulley and use of steel frame pulleys are problematic.

Educational plastic pulley with steel frame

The most common educational plastic pulleys with steel frame are:

  • Single pulley with a 50 mm (diameter) sheave.
  • Double parallel pulley with a 50 mm (diameter) sheave.
  • Triple parallel pulley with a 50 mm (diameter) sheave.
  • Quadruple parallel pulley with a 50 mm (diameter) sheave.
  • Double tandem pulley has sheaves with 50 and 40 mm diameters.
  • Triple tandem pulley has sheaves with 50, 40 and 30 mm diameters.
  • Replacement sheaves, pack of 5
The second most popular educational pulleys are plastic pulleys with aluminum frame. These pulleys are available in the same combinations as the above steel frame pulleys, but they have different part numbers. Educational plastic pulleys with Aluminum frame

Most pulleys cannot be disassembled and reconfigured. If you need a pulley block that can come apart and reassembled you may select the blue hand made pulleys.

Hand made pulleys

Screws and nuts are used to assemble a complete set of pulley blocks for educational applications. These pulleys have no welded and no riveted parts. You can simply unscrew the shaft and frame and separate all the parts for practice, education or for reconfiguration.

The single pulley, double parallel pulley and triple parallel pulley are made of 50-mm sheaves.

The tandem pulleys are made of 50-mm, 40-mm and 30-mm sheaves.
