Pinion shaft is made of alloy steel forgings, and herringbone gears are machined on the shaft, using medium-hard tooth flour. In order to facilitate maintenance, a single-row centripetal long cylindrical roller bearing with no stop edge on the inner ring is selected. Both ends of the shaft extend, and pulley or chain wheel can be installed at either end.
