What is an MRP Pulley?

What are your design options when you need a belt drive system that can transmit higher torque, won't slip, has no vibration, and is very quiet? The answer is an MRP drive system or multi-ribbed pulley and belt also know as Poly V and Micro V®️

MRP PulleyWhat is an MRP Pulley?

MRP pulleys, or multi-ribbed pulleys, feature lengthwise grooves across the circumference of the pulley. These grooves help lend MRPs their signature drive by adhesion. When used in conjunction with Multi-rub belts the surface area of the pulley is maximized, allowing for the use of smaller pulleys than standard v-belts.

Drive widths can also be reduced because of the increase in surface engagement, rather than increased surface area. This allows for an increase in horsepower, per inch of belt width.

Advantages of Multi-Ribbed Pulleys

Multi-ribbed pulleys, as mentioned above, offer increased horsepower with smaller width belts. This makes them ideal for applications where a smaller belt is advantageous.

This type of pulley also offers users a quiet operation with minimal vibration, making them an attractive pulley solution for applications where noise restraints are in place.

MRP Applications

Multi-rib pulleys can be found in many applications across a huge variety of industries. Because of the advantages associated with using multi-rib pulleys, they are often used in applications that require both long service life and high horsepower.

Some of the most common applications include:

  • Conveyors
  • Auto aftermarket
  • CNC machines
  • CMM coordinate measuring machines
  • Mobility lifts
  • Agricultural mechanization
  • Exercise equipment
  • Medical equipment
  • Automation
  • High-speed machine tools
  • Compressors
  • Microwave ovens
  • Office equipment
  • Display components
