Lubrication is vital for prolonging the lifespan of hydraulic cylinders due to friction generated by various parts during operation. Within the hydraulic cylinder, components undergo friction, including piston rings rubbing against cylinder walls and the interaction between the crankshaft and bearings. so lubrication can protect the hydraulic system, as friction can escalate the workload on hydraulic cylinders and potentially disrupt the entire system. Now, have a quick look at the guide on how to lubricate hydraulic cylinders.
