Poly V-Belt Pulley (sheave) Size

The size of a Poly V-Belt Pulley (Sheave) depends on various factors, including belt profile, number of ribs, pitch diameter, and application requirements. Poly V-belt pulleys are designed for high-speed, high-efficiency power transmission, providing superior grip and reduced slippage compared to traditional V-belt pulleys. These pulleys are commonly used in automotive, industrial machinery, HVAC systems, and power transmission applications.

Standard Poly V-Belt Pulley Sizes

Poly V-belt pulleys come in different groove profiles, including PH, PJ, PK, PL, and PM, which correspond to different belt widths and power transmission capacities. Below are some standard size ranges:

Selection Considerations

RPM & Speed Ratio: Choose the pulley size based on required speed ratios in the drive system.
Belt Type & Rib Count: Ensure compatibility with the Poly V-belt profile (PJ, PK, etc.).
Load Capacity & Torque Requirements: Larger pulleys handle higher loads but require more space.
Mounting Type: Options include fixed bore, taper lock, and QD bushing systems for easy installation.
