GREASING UNIT

867 376 19A GREASING UNIT Serving as a crucial support element, this GREASING UNIT allows shafts in high-load areas, like the feed system's drive or idler sprockets, to rotate freely and with proper alignment. It carries radial and axial loads, reducing friction and preventing wear on the shaft itself. A correctly functioning unit is fundamental for a smooth and consistent feed force during the drilling cycle.

When this bearing starts to wear, it can introduce unwanted movement or play into the system. For instance, a worn bearing in the feed can cause the feed chain to run misaligned, leading to jerky drifter travel and accelerated wear on the chain and feed rail. Eventually, a complete failure can cause the shaft to seize, resulting in a sudden and costly breakdown.

A key symptom of a failing bearing is a distinct grinding or rumbling noise that gets worse under load. You might also feel excessive heat from the bearing housing after a period of operation. If you notice any wobble or play in the shaft it supports, schedule a replacement to avoid a major failure.
