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®️. 

**What is an MRP Pulley?**

MRP pulleys, or [multi-ribbed pulleys](https://www.torquetrans.com/multi-v-nylon-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
