Pinion shaft is a very important part for mud pump. The pinion shaft is made of forged alloy steel, on which a herringbone gear with the medium-hard teeth surface is machined. For easy maintenance, single row radical cylindrical roller bearing with double ribbed outer ring is used. The pinion shaft ends are prolonged so that sheave or sprocket can be mounted on either end.
The Gear Shaft is made from 42CrMo and with a high precision double helical gear. The precision gears ensure our pinion run very smoothly with almost no noise and vibration , increased the power transmission efficiency. Backlash in the gears is minimal and no pre-wear is required for smooth running.
