Certain components in the crusher (pinion shaft and bearings, pinion and eccentric gears, eccentric bushing, and step bearing) require continuous oil lubrication. The lubrication system is comprised of an oil reservoir, pumps, heat exchanger, and protective instrumentation. Its function is to lubricate and cool the crusher moving parts and keep them clean.

The spider bearing is lubricated with grease. The grease is drawn from a grease barrel and injected into the bearing at preset intervals by a timer circuit.

The hydroset system is used to change the gap between the mantle and concaves by raising or lowering the mainshaft assembly and mantle from underneath.

Sometimes very large rocks or items of tramp steel enter the crushing chamber. In a gyratory crusher these can cause the mainshaft to move suddenly upward in a "jumping" action. When this occurs a balance cylinder in the oil line maintains hydraulic support under the mainshaft. This prevents it from dropping suddenly, and damaging the crusher, when the condition is relieved.
