V belts Note: Every turn of the adjustment screw moves the flange by 1/16".Pulley adjustment Modify the sheave pitch diameter by using the adjustment screw. Every turn of the adjustment screw moves the flanges by 1/16".Once the required diameter is obtained, tighten the locking screw.Adjustable pitch sheaves Adjustable speed sheaves are used primarily in the air handling industry. Optimal fan working speed is easily obtained by simply adjusting one of the pulleys.Adjustable pitch sheaves are made of durable gray cast iron class 30.Line covers from fractional light duty (less than 1 Hp) to heavy duty (40 Hp)
