This bushing, identified as a slide insert, acts as a wear interface between a rotating shaft and the stationary frame of the grain seeder. It provides a low-friction bearing surface that maintains the alignment of the metering or drive shaft within the seed drill chassis. Wear on the bushing’s inner diameter increases clearance, allowing the shaft to wobble. This misalignment can cause uneven seed metering or accelerated wear on the shaft itself. The flange on this bushing locates it axially against the housing face, preventing end-play in the assembly.
