Preventive Maintenance vs. CBM
Differences Between Preventive and Condition-Based Maintenance
Preventive maintenance (PM) and condition-based maintenance (CBM) are distinct maintenance strategies.
PM is a time-based or meter-based strategy that involves performing maintenance tasks at regular intervals, regardless of the equipment’s condition.
CBM, on the other hand, is a proactive maintenance strategy that involves performing maintenance tasks based on the equipment’s actual condition.
The main differences between PM and CBM are:
- Maintenance Scheduling: PM schedules maintenance tasks regularly, whether the equipment needs it or not. CBM schedules maintenance tasks based on the equipment’s condition, ensuring maintenance is performed only when necessary.
- Maintenance Tasks: PM involves performing routine maintenance tasks, which can sometimes be unnecessary. CBM involves performing maintenance tasks based on the equipment’s condition, which can lead to more targeted and effective maintenance.
- Maintenance Costs: PM can result in higher maintenance costs due to unnecessary maintenance tasks. CBM can reduce maintenance costs by performing maintenance tasks only when necessary, avoiding unnecessary work, and focusing resources where they are needed most.
- Equipment Reliability: CBM can improve equipment reliability by detecting potential failures before they occur. This proactive approach helps prevent unexpected breakdowns and extends the life of the equipment. PM, while useful, may not detect potential shortcomings until it’s too late, leading to unplanned downtime.

CBM is a more proactive and cost-effective maintenance strategy that can improve equipment reliability and reduce maintenance costs. By focusing on the actual condition of the equipment, CBM ensures that maintenance efforts are directed where they are needed most, leading to more efficient and effective maintenance practices.
