Detection vs. analysis – knowing not just what, but why
An experienced maintenance technician can often “hear” a machine problem just walking thorough a facility. “That bearing is going; we need to replace it,” he’s likely to say.
Knowing that a bearing needs replacing is good, but knowing why it needs replacing is even better. Because when you get to the root of the problem, you can solve it, helping to ensure that the new bearing you install lasts a lot longer.
Sure, swapping out a bearing that is showing wear by vibrating heavily will get you up and running again. But for how long? If the original problem still exists, the bearing will soon fail again, resulting in maintenance costs and possible downtime.
The fact is, if you are not running a condition monitoring program, you are running a bearing exchange program. That’s because some other machinery problem is usually the cause of premature bearing failure – things like misalignment, looseness or imbalance.
A first class condition monitoring programme enables you to identify the cause of the problem so you can address it to get maximum life from your bearings, and get advance notice of bearing wear so you can plan for repair actions and minimize machine downtime.
