5 Pro Tips to Extend the Life of Your Sealmaster Bearing

Sealmaster bearings are known for their durability, but even the best components require proper care to maximize their lifespan. This article offers five practical tips, gleaned from years of working with industrial machinery, to help you get the most out of your Sealmaster bearings, reducing downtime and saving money. These insights go beyond the manufacturer’s recommendations and address common issues often overlooked.

Before diving into the tips, let’s cover some foundational knowledge. Sealmaster is a well-respected brand known for its quality bearings, particularly in mounted bearing units. These units, typically housed in cast iron or steel, are designed for easy installation and alignment in a variety of applications. Key factors contributing to their performance include:

• Material Quality: Sealmaster bearings utilize high-grade steel for the bearing races and rolling elements.
• Seal Design: Their sealing systems are crucial for preventing contamination and retaining lubricant.
• Housing Design: The housing provides support and facilitates mounting.

Understanding these elements allows for more informed maintenance and troubleshooting.

What Types of Sealmaster Bearings Are There?

Sealmaster offers a variety of bearing types, each designed for specific applications. Some common types include:

• Ball Bearings: Versatile and suitable for moderate loads and speeds.
• Roller Bearings: Designed for heavier loads and higher shock resistance.
• Mounted Bearings: Pre-assembled units with housings for easy installation.

Knowing the specific type of Sealmaster bearing you are working with is crucial for selecting the appropriate maintenance procedures and lubricants.

Lubrication is arguably the most critical aspect of bearing maintenance. Insufficient or incorrect lubrication is a leading cause of bearing failure. However, simply adding grease isn’t enough.

• Choose the Right Grease: Sealmaster typically specifies the appropriate grease type in their documentation. Refer to the bearing’s datasheet or consult a lubrication chart. Using the wrong grease can lead to incompatibility issues, accelerated wear, and reduced bearing life. Lithium-based greases are often recommended for general applications.
• Avoid Over-Greasing: While under-greasing is detrimental, over-greasing is equally harmful. Excess grease can create excessive heat and pressure, damaging the seals and causing premature failure. Follow the manufacturer’s recommended greasing intervals and amounts. A grease gun meter can help with precise dispensing.
• Purge Old Grease: When re-greasing, ensure you purge the old grease from the bearing. This removes contaminants and prevents grease build-up. Observe the grease coming out of the bearing – if it’s discolored or contains debris, continue greasing until clean grease appears.
• Consider Automatic Lubrication Systems: For applications requiring frequent lubrication or in hard-to-reach areas, consider installing an automatic lubrication system. These systems deliver precise amounts of grease at pre-set intervals, ensuring consistent lubrication and reducing the risk of human error.

My personal experience has shown that investing in a quality grease gun with a meter and strictly adhering to a lubrication schedule can significantly extend bearing life. I’ve seen bearings last twice as long simply by implementing proper lubrication practices.

Misalignment is another common culprit behind premature bearing failure. Even slight misalignment can create uneven load distribution, leading to increased wear, heat, and vibration.

• Use Alignment Tools: Employ laser alignment tools or dial indicators to ensure proper alignment of the shaft and bearing housing. These tools provide precise measurements and allow for accurate adjustments.
• Check for Soft Foot: Soft foot occurs when one or more of the mounting feet of the bearing housing don’t make proper contact with the base. This can cause distortion and misalignment. Use shims to correct soft foot before tightening the mounting bolts.
• Inspect Coupling Alignment: Ensure that the coupling connecting the shaft to the motor or other equipment is properly aligned. Misaligned couplings can transmit excessive forces to the bearings, leading to premature failure.
• Consider Self-Aligning Bearings: If misalignment is unavoidable due to the application, consider using self-aligning bearings. These bearings are designed to accommodate a certain degree of misalignment without compromising performance.

In my experience, taking the time to properly align bearings during installation or maintenance is an investment that pays off in the long run. I’ve seen misalignment cause catastrophic bearing failures within weeks, highlighting the importance of this step.

Contamination is a major enemy of bearings. Dirt, dust, moisture, and other contaminants can infiltrate the bearing, causing abrasion, corrosion, and lubricant degradation.

• Implement Sealing Solutions: Ensure that the bearing seals are in good condition and properly installed. Replace damaged or worn seals immediately. Consider using additional sealing measures, such as labyrinth seals or lip seals, in harsh environments.
• Maintain Cleanliness: Keep the surrounding area clean and free of debris. Regularly clean the bearing housing and surrounding equipment. Use appropriate cleaning agents that are compatible with the bearing materials and lubricants.
• Use Filtered Lubricants: Ensure that the lubricant being used is clean and free of contaminants. Use filtered grease guns and lubrication systems. Consider installing filters in the lubrication lines to remove contaminants before they reach the bearing.
• Inspect for Corrosion: Regularly inspect the bearings for signs of corrosion. If corrosion is detected, take immediate action to prevent further damage. This may involve cleaning the bearing, applying a rust inhibitor, or replacing the bearing altogether.

I once worked in a dusty environment where bearing failures were frequent. By implementing a strict cleaning schedule and upgrading the bearing seals, we were able to significantly reduce the number of failures and extend bearing life.

Vibration and temperature are key indicators of bearing health. Changes in vibration or temperature can signal the onset of problems, allowing for early intervention and preventing catastrophic failures.

• Use Vibration Analysis: Implement a vibration analysis program to monitor the vibration levels of the bearings. This involves using specialized equipment to measure the vibration frequency and amplitude. Changes in vibration patterns can indicate bearing wear, misalignment, or other problems.
• Monitor Temperature: Regularly monitor the temperature of the bearing housing. Excessive heat can indicate over-lubrication, under-lubrication, misalignment, or bearing damage. Use a non-contact infrared thermometer to measure the temperature of the bearing housing.
• Establish Baseline Readings: Establish baseline vibration and temperature readings for each bearing when it is new or in good condition. This provides a reference point for comparison. Track changes in vibration and temperature over time to identify potential problems.
• Invest in Condition Monitoring Systems: Consider investing in condition monitoring systems that continuously monitor vibration, temperature, and other parameters. These systems can provide early warnings of bearing problems, allowing for proactive maintenance.

I’ve personally used vibration analysis to detect a failing bearing weeks before it would have completely failed, preventing a costly shutdown. The ability to identify problems early is invaluable in maintaining equipment uptime.

Even the best bearings can fail prematurely if they are not properly installed and handled. Careless installation can damage the bearing or introduce contaminants, leading to reduced life.

• Use Proper Tools: Use the correct tools for installing and removing bearings. Avoid using hammers or other tools that can damage the bearing. Use bearing pullers and bearing heaters to facilitate installation and removal.
• Maintain Cleanliness: Keep the bearing and surrounding area clean during installation. Avoid touching the bearing with bare hands, as this can transfer contaminants. Use clean gloves or lint-free cloths.
• Follow Manufacturer’s Instructions: Always follow the manufacturer’s instructions for installing and maintaining bearings. These instructions provide specific guidance on lubrication, alignment, and other critical factors.
• Store Bearings Properly: Store bearings in a clean, dry, and protected environment. Avoid storing bearings in direct sunlight or in areas with high humidity. Keep bearings in their original packaging until they are ready to be installed.

I witnessed a situation where a bearing was installed incorrectly, resulting in immediate failure upon start-up. This highlighted the importance of following the manufacturer’s instructions and using proper installation techniques.
