What Is Mean Time Between Failures (MTBF)?
MTBF stands for Mean Time Between Failures , one of the most widely used maintenance metrics for measuring equipment reliability. It tells you, on average, how long a repairable asset operates before experiencing an unexpected failure. The longer the MTBF, the more reliable your equipment is likely to be. For maintenance managers, engineers, and facility teams, MTBF is more than just a number. It helps identify problem assets, improve preventive maintenance schedules, reduce downtime, and make better repair or replacement decisions. What Is Mean Time Between Failures (MTBF)? Mean Time Between Failures is the average operating time between one equipment failure and the next for a repairable asset. For example, if an air compressor runs for 2,000 hours over several months and experiences four unexpected failures during that time, its MTBF would be: MTBF = Total Operating Time ÷ Number of Failures MTBF = 2,000 hours ÷ 4 = 500 hours This means the compressor operates for an average of 500...
