What Is MTBF?
MTBF (Mean Time Between Failure) is a reliability metric expressing the average time a repairable system operates between consecutive failures. For bearing applications, MTBF measures how often bearings need emergency replacement versus their expected service interval.
Improving MTBF
Correct bearing selection, proper installation, adequate lubrication, contamination control, and condition monitoring are the five pillars of MTBF improvement. Our Oil & Gas Case Study demonstrates a 3.1x MTBF improvement through systematic reliability engineering.
Frequently Asked Questions
How is MTBF calculated?
MTBF = Total operating time / Number of failures. For example, if 10 pumps operate for 50,000 total hours and experience 5 bearing failures, MTBF = 50,000/5 = 10,000 hours. Higher MTBF indicates better reliability. Our Oil & Gas Case Study achieved a 3.1x MTBF improvement.
