Foaming gear oil not only creates a mess, it can lead to poor performance and early failure. Understanding the conditions that cause foam can keep it from spinning out of control.
Foaming in industrial gearboxes is one of the most frequent complaints that gear lubricant suppliers hear. Foam does not pump or circulate, and it reduces the effectiveness of the lubricant, resulting in accelerated gear wear and overheating. Foam can also create a safety hazard when it spills onto the floor. Its no wonder then that when foam occurs, the customer wants it fixed, and fast!
