Custom Metal Multi Ribbed pulleys with a 2” diameter or less are machined from aluminum for long life and dependable service. For larger volume orders, we can mold and machine custom options.

Compared to similar pulleys, Multi Ribbed pulleys offer smoother running and can run at higher speeds thanks to their multi ribbed design. This design also offers low inertia.

Multi Ribbed Pulley Applications:

  • Conveyors
  • Auto aftermarket
  • CNC machines
  • CMM coordinate measuring machines
  • Any application that requires a belt

You may not know exactly what your design requires at this point, but you can draw upon our experience to assist you in the selection process. First, we'll review some basic requirements, then we can agree on a design and proceed with the quotation process.

Designing the Perfect Pulley

Because Multi Ribbed pulleys are most often used to replace a pulley that has failed within an existing system, most of the Multi Ribbed pulleys we sell are custom designed to meet individual specifications. We suggest downloading and completing the Multi-Groove Pulley Buying Checklist before you order. This resource will guide you through collecting the information necessary to ensuring the pulley you order will meet your needs.

The checklist includes information on and instruction for determining:

  • Application information

  • Drive vs Driven

  • Belt type

  • Pulley specs

  • Hub

  • Bore

  • Insert

  • Keyway

  • D-Bore measurements

  • Set screw

  • Flange

All profiles available in equivalent metric dimensions. Consult the factory to discuss diameters larger than 10" or 250mm.
