SKF ball bearings are renowned worldwide for their precision, durability, and ability to perform under demanding conditions. Whether you are using SKF deep groove ball bearings or other specialised variants, proper maintenance is essential to maximise their lifespan, maintain smooth operations, and reduce costly downtime.

In this guide, we’ll explore practical maintenance tips to keep your SKF ball bearings in top condition for years to come.

1. Understand Your SKF Ball Bearings

Before diving into maintenance, it’s important to understand the type of bearing you’re working with. SKF deep groove ball bearings are among the most widely used types, thanks to their versatility and ability to handle both radial and axial loads. They are commonly found in electric motors, gearboxes, pumps, and various industrial machinery.

Other types of SKF ball bearings may include angular contact, self-aligning, and thrust ball bearings, each designed for specific applications. Knowing the type and its operational requirements is the first step in effective maintenance.

2. Keep Bearings Clean and Contaminant-Free

Contamination is one of the leading causes of premature bearing failure. Dust, dirt, moisture, and chemical residues can quickly degrade the lubrication and cause surface wear.

Maintenance Tip:

• Always store bearings in their original packaging until ready for installation.
• Use clean gloves when handling bearings to prevent introducing contaminants.
• Install protective seals or shields, especially in harsh environments.

For SKF deep groove ball bearings in particular, clean environments help maintain their precision fit and smooth rotation.

3. Ensure Proper Lubrication

Lubrication is the lifeline of all SKF ball bearings. It reduces friction, prevents metal-to-metal contact, and minimises wear. Over time, lubrication can deteriorate or become contaminated, so regular checks are vital.

Best Practices for Lubrication:

• Use the lubricant type recommended by SKF for your specific bearing type.
• Apply the correct quantity – too little can lead to overheating, while too much can increase drag.
• Re-lubricate at intervals based on operating speed, load, and environmental conditions.

For sealed SKF deep groove ball bearings, the factory-applied grease may last the bearing’s entire service life, but always refer to SKF guidelines for specific intervals.

4. Avoid Overloading and Misalignment

Excessive loads and shaft misalignment can put unnecessary strain on SKF ball bearings, leading to premature wear and failure.

Prevention Tips:

• Verify that the bearing selected matches the load and speed requirements of your machinery.
• Check and adjust shaft alignment during installation and routine inspections.
• Monitor for vibration or noise, which can indicate misalignment or imbalance.

SKF offers alignment tools that can help maintain optimal positioning, especially in high-speed applications.

5. Monitor Temperature and Vibration

Unusual temperature rises or excessive vibration are often early warning signs of bearing issues.

Monitoring Practices:

• Use infrared thermometers to detect abnormal temperature changes.
• Conduct regular vibration analysis to spot imbalance, misalignment, or lubrication problems.
• Address issues immediately to prevent further damage.

SKF’s own condition monitoring tools can make this process more precise and efficient.

6. Follow Correct Installation and Removal Practices

Improper installation is another common cause of reduced bearing life.

Installation Guidelines:

• Use the proper SKF mounting tools instead of makeshift methods like hammering.
• Avoid applying direct force to the bearing’s rolling elements.
• Heat-assisted mounting can be used for larger bearings, following SKF recommendations.

Similarly, when removing SKF ball bearings, use pullers or dismounting tools to prevent damage to the shaft or housing.

7. Schedule Preventive Maintenance

Reactive maintenance—fixing bearings only when they fail—can lead to costly downtime. Instead, set up a preventive maintenance schedule.

Preventive Maintenance Steps:

• Keep a log of lubrication intervals, temperature readings, and vibration data.
• Inspect bearings during machine shutdowns to identify early signs of wear.
• Replace bearings before they reach the end of their service life to avoid unexpected breakdowns.

Maximising the Lifespan of Your SKF Ball Bearings

Maintaining SKF ball bearings—whether they are SKF deep groove ball bearings or other specialised types—requires consistent care, the right tools, and adherence to manufacturer recommendations. By keeping bearings clean, well-lubricated, properly aligned, and regularly monitored, you can ensure optimal performance, minimise downtime, and extend the service life of your machinery.

For businesses and industries that rely on continuous, high-performance operation, these maintenance tips are not just best practices—they are essential for long-term success.
