Poly-V Pulley

A poly V pulley (micro-V pulley / ribbed pulley) is a modern power transmission component featuring multiple parallel V-shaped longitudinal ribs on its outer surface, combining the flexibility of a flat belt with the high grip strength of a V-belt. Thanks to its wide and thin profile, it can transmit high torque even at high rotational speeds.

Key Advantages

High Speed and Power Capacity: Delivers superior performance in high-speed and high-ratio drives thanks to its thin profile and large contact area.

Low Vibration and Quiet Operation: Minimizes vibration and operating noise by distributing the load evenly across its multi-ribbed structure.

Compact Design: Allows multiple shafts to be driven simultaneously in tight spaces, saving valuable system space.

Flexibility: Operates smoothly even in systems requiring tight bending radii where small-diameter pulleys are used.

Applications

It is widely preferred in automotive auxiliary equipment drive systems (alternators, power steering, air conditioning compressors), washing machines, compressors, small household appliances, lawnmowers, and high-speed industrial machinery.
