You do not think about lubrication until something goes wrong. It is too late until then. A gearbox that has been running for years suddenly starts making a noise. Then it gets louder and hotter. Metal shavings are in the oil and you are staring at a repair bill that makes your stomach turn before you know it. Bad lubrication is the primary reason behind these issues. Machines are tough, but they’re not invincible. They rely on gear oils to keep their moving parts protected. Gears run smoothly, and breakdowns do not happen when the right industrial gear oils are in place. However, everything changes when lubrication fails.
