Frequently Asked Questions (FAQs)

1. What are the different types of V-belt pulleys?

V-belt pulleys come in various styles and options, including A-section, B-section, C-section, D-section, 3V-section, 5V-section, 8V-section, variable pitch, double groove, and metric pulleys. There is a wide range of options available, with over 8,000 SKUs of different V-belt pulleys alone.

2. How do you match a V-belt to a pulley?

To match a V-belt to a pulley, ensure that the bottom or narrowest part of the belt does not touch the center of the v-groove pulley. Instead of matching the exact pulley you have, try to get a pulley with a slightly smaller outside diameter.

3. How do I choose a V pulley?

When choosing a V pulley, consider factors such as the speed (rpm) of the drive and driven shafts, motor power (HP or KW), type of prime mover or motor and starting style for electric motors, shaft diameter of drive and driven shafts (inch or metric), and duty cycle (to allow selection of a suitable service factor). These factors will help you select the appropriate V pulley for your needs.

4. What is the minimum pulley size for V-belt?

The minimum pulley size for a V-belt should be at least four times the cross-sectional diameter of the belt. However, for higher speeds (above 2500 R.P.M.), the 4:1 minimum ratio must be increased proportionately to account for hysteresis heat build-up due to frequent flexing around the pulleys.

5. How deep should a v-belt sit in a pulley?

A V-belt should sit in the pulley groove with the top of the belt within 1/16-inch of the outer surface of the pulley. If the belt top is deeper in the groove, it indicates wear in either the groove or belt, which can significantly reduce the remaining belt life.
