When to Use a Cogged v Belt?

However, cogged belts may be a better choice when vibration damping is needed or shock loads cause abrupt torque changes that could shear a synchronous belt's teeth. Synchronous belts also make a whirring noise that might be objectionable in some applications.

Are notched V-belts better?

Notched belts can use the same pulleys as cross-section standard V-belts. They run cooler, last longer, and are about 2% more efficient than standard V-belts. ... 2 In contrast, V-belts have a sharp reduction in efficiency at high torque due to increased slippage.

Why should you use a narrow groove V-belt instead of a classical V-belt in a new installation?

Why should you use a Narrow Groove V-belt instead of a Classical V-belt in a new installation? They can handle more power, they use smaller diameter sheaves, and are more economical than a classical V-belt.
