This gear with integrated bearing transmits rotary motion from the drive input to the metering or conveying mechanism inside the baler. It is mounted on the shaft that carries the feeding or tying components, and the pre-assembled bearing supports radial and axial loads during operation. A worn gear or bearing produces irregular rotation, leading to inconsistent bale density or jamming in the pickup area. The manufacturer machines the gear teeth and bearing race to the same tolerances as the original assembly, so no shimming or adapter spacers are required during installation. When replacing, clean the shaft journal and apply the specified thread-locking compound to the retaining fastener.
