Manufacturer’s Guide to Industrial Preventive Maintenance

Industrial preventive maintenance is a proactive maintenance approach to maintaining industrial equipment and machinery that involves performing regular inspections and routine maintenance work to prevent unexpected breakdowns, extend the lifespan of assets and improve operational efficiency. Rather than waiting for equipment to fail, preventive maintenance (PM) focuses on identifying and addressing potential issues before they escalate into costly repairs or unplanned downtime. 

Needless to say, manufacturers depend heavily on a preventive maintenance plan to ensure their industrial equipment stays in good working condition. Otherwise, the productivity of their manufacturing facility is at stake. 

For example, consider the manufacturer that produces your smartphone. This device is made up of several components — including processors, memory chips, screens and batteries — that are all put together at separate points along an assembly line. Conveyor belts play a key part in moving these parts along the assembly line, so it’s crucial that they’re operating at peak performance to ensure production quotas are met. Creating a preventive maintenance process that includes tasks such as lubricating chains and checking belt alignment can help avoid equipment breakdowns, resulting in several benefits that affect the manufacturer’s bottom line. 

Let’s dive in to learn more about the different ways manufacturers can introduce industrial preventive maintenance into their workflows and how having these maintenance procedures in place can lead to significant cost savings and productivity improvements overall. 

Types of Preventive Maintenance in Manufacturing 

Preventive maintenance in manufacturing can be categorized into four main types: time-based, usage-based, condition-based and predictive maintenance. Each type of preventive maintenance provides a proactive approach to maintaining equipment, whether it be through traditional scheduled maintenance or by using sensors and other technologies to help predict when maintenance is necessary. All four are defined as follows:

Time-Based Maintenance

Time-based maintenance involves performing maintenance tasks at regular, scheduled intervals, regardless of the equipment’s condition. These intervals are typically determined by manufacturer recommendations or historical performance data. For instance, a factory might schedule monthly lubrication of conveyor belts or annual replacement of HVAC filters. While this method ensures consistent care, it may occasionally lead to unnecessary maintenance if equipment is in good condition. However, time-based maintenance is ideal for critical machinery with predictable wear patterns.

Usage-Based Maintenance

Usage-based maintenance focuses on performing maintenance based on how often the equipment is used. For example, a machine that operates 500 hours per month might require a filter replacement after every 1,000 hours of operation. This method ensures maintenance aligns with the actual workload of the equipment, reducing the risk of premature wear or over-maintenance. It’s particularly effective for machines with variable usage rates, such as CNC machines or forklifts in a factory setting.

Condition-Based Maintenance

Condition-based maintenance involves monitoring the actual condition of equipment to determine when maintenance is necessary. This approach uses sensors, inspections or diagnostic tools to identify signs of wear or performance decline, such as unusual vibrations, temperature fluctuations or oil contamination. For example, a manufacturer might use vibration analysis to detect misalignment in a motor before it fails. Condition monitoring ensures maintenance is only performed when needed, optimizing resources while preventing unexpected breakdowns.

Predictive Maintenance

Predictive maintenance takes condition-based maintenance a step further by leveraging advanced technologies like IoT sensors, machine learning and data analytics to predict when equipment will require maintenance. By analyzing historical data and real-time performance, predictive maintenance identifies potential issues well before they cause failure. For instance, a packaging plant might use predictive analytics to forecast when a bottling machine’s bearings will fail based on historical trends. This method is highly cost-effective, as it prevents downtime, reduces unnecessary maintenance and extends equipment lifespan.

Each of these types of preventive maintenance has its strengths and is best suited for specific scenarios. Time- and usage-based approaches offer straightforward scheduling, while condition-based and predictive maintenance rely on technology for precise interventions. By combining these strategies, manufacturers can create a robust maintenance program that minimizes costs, maximizes uptime and ensures operational efficiency.

How Manufacturers Can Implement an Industrial Preventive Maintenance Plan

Implementing a preventive maintenance plan in manufacturing requires a structured approach to maximize efficiency and minimize downtime. Here are the key steps:

1. Identify your preventive maintenance goals: Define clear objectives for your preventive maintenance program, such as reducing equipment downtime, increasing productivity or extending asset lifespan. Goals provide direction and will help you measure success.
2. Prioritize assets for preventive maintenance: Focus on critical assets that significantly impact production or have higher costs for spare part replacements. Conduct a risk assessment to identify equipment prone to failure.
3. Create SOPs and checklists: Develop standard operating procedures (SOPs) and detailed maintenance checklists to ensure PM tasks are performed consistently and thoroughly.
4. Train your maintenance team: Provide training to your maintenance technicians on specific PM techniques, safety protocols and the use of tools and technology to ensure proper execution.
5. Create a PM calendar: Establish a preventive maintenance schedule based on time intervals, usage or equipment condition. Align schedules with production cycles to minimize disruptions.
6. Use a computerized maintenance management system (CMMS): Implement a CMMS software (also referred to as a preventive maintenance software) to organize, automate and track preventive maintenance tasks, asset history and resource allocation.
7. Review and optimize: Regularly review program performance, gather feedback and adjust schedules or methods to improve efficiency and adapt to changing needs.
