More about Rubber Bands and Belts

About Rubber Bands and Belts

A rubber belt runs over pulleys or wheels to drive another axle, a bit like the fan belt in a car. Bands can also provide tension, for example to pull a part back into place. Old rubber can dry out and crack, so a fresh band often revives an old mechanism.

  • Belts drive one pulley from another
  • Bands add tension to moving parts
  • Size is given as an approximate measurement in studs
  • Band and belt holders belong here too

Finding the right part

  • Search on the part number to get the right size.
  • Check the condition: used rubber can be less elastic.
  • Building a mechanism? Also see Technic parts.
