Leaking seals are the most common reason for the performance problems of gearboxes.


Gear boxes and Transmissions are often the most neglected components of heavy industrial equipment. It’s out of sight out of mind, however if a gearbox has issues or fails it can stop production completely until the issues are resolved, costing a lot of money in downtime.

By far the most common issue is leaking oil. This is also often seen as normal to lose oil and just top up, but this can lead to even bigger issues over time. What can start as a small leak that no one really worries about, can lead to a loss of more oil over time as well as contamination of the oil and damage to the gear box shortening it’s life and leading to additional costs for parts, not to mention unscheduled downtime for failures.


By thinking ahead and applying a solution to correct the leaking seal issues in gearboxes rather than just topping up as oil is lost, with the thought that this is just normal, a lot of NORMAL problems can be avoided.

By far the simplest way to get ahead of gearbox problems, including leaking seals, contamination and dry start wear and tear, is to invest in better quality oils. Choosing an oil with additional additives to protect against traditional problems saves time and money in the long run. By using high quality gear and transmission oils the negative effects on equipment and machinery are greatly reduced, and it becomes one less thing to have to worry about in your ongoing maintenance scheduling, so you can actually focus on more important things.
