Idler pulleys are standard pulleys with an integrated bearing that causes them to spin freely. This is useful for adding tension a belt system without putting additional load on the motor. They can also be used to route belts around so they're not in the way of other parts of the system.

Features

  • Free-spinning idler for adding support or tension to a belt system
  • Fits onto a 12mm shaft
  • For use with GT5 size belt
  • Includes two mounting spacers

Assembly

Accessories

The included mounting spacers can be slid onto a bolt, one on each side of the pulley.

The spacer only contacts the inner bore of the pulley, so it can be securely mounted while still allowing the pulley to spin freely.


Guides

Belts

This pulley can be used with any GT5 series belt. The size of belt required depends on the desired distance between your two pulleys; for installation details see the Rotary Motion Guide.
