    • V-belts have no slippage and alignment problems as observed in flat belts. Slipping is negligible due to wedging action. Power transmitting capacity increases due to wedging action due to smaller arc of contact and increases pulling capacity of belt.

    • They have high reduction ratios up to 7:1 and have positive drive.

    • These belts cannot transmit power over long centre distances.

    • V-belts have low efficiency than flat belt drives and ranges between 80 % to 96 %.

    • V- belts are used to drive compressors, drive blowers.
