Best Practices for Lubricating Industrial Bearings During Winter Months
Winter isn’t kind to industrial machinery, and moving components like bearings often bear the brunt of the season. As temperatures plummet, lubricants thicken, moisture creeps into systems, and friction becomes a heightened problem. Without a seasonal lubrication strategy, winter can wear down even the toughest equipment. But with smart practices, you can keep your bearings (and your equipment) running smoothly.
If your equipment suffers a drop in reliability or efficiency during the colder months, don’t wait to get it serviced. Throughout December, GES is making it easy to Stack & Save on equipment repairs!

Understand cold-weather effects on lubricants
When temperatures change, so do a lubricant’s properties. As lubricants become exposed to conditions outside of normal operating specifications, they can struggle to adapt. Bearings suffer the consequences: increased wear and potential damage.
- Cold temperatures increase viscosity, reducing the flow and effectiveness of oils and greases.
- Condensation from temperature changes can introduce water into closed lubrication systems.
- Less effective lubricants can lead to metal-on-metal contact, hastening wear and tear on bearings.
- Cold-starting equipment puts more stress on moving parts—particularly those poorly lubricated.
Choosing the right lubricant for winter keeps your equipment running smoothly when temperatures drop. The best options have key features like cold weather flowability and water resistance. They safeguard against rust and corrosion while keeping metal components properly coated and protected.
- Low-temperature lubricants are designed to stay fluid even in freezing conditions, for smooth performance.
- Water-resistant formulas protect against condensation by repelling moisture and preventing corrosion.
- High-performance synthetic options keep their consistency and properties across a range of temperatures.
Create a winter lubrication schedule
Bearings don’t just need the right lubricant — they need it at the right time. In fact, cold weather conditions open the door to an added layer of maintenance. Winter lubricant checks should include seals and housings for cracks or wear that could let contaminants in. Watch for early warning signs like pitting in bearings and any lubricants that appear cloudy, discolored, or smell burnt – these need immediate replacement to prevent damage.
Keep these best-practices in mind as you take a mindful approach to seasonal lubrication and bearing maintenance:
- Increase frequency for outdoor equipment. Machinery exposed to the elements experiences greater temperature swings and moisture risks. More frequent lubrication protects bearings against harsh conditions.
- Monitor heavily used bearings. High-use equipment endures constant strain, which accelerates wear in cold weather. Regular checks and lubrication help them run smoothly despite the added stress.
- Don’t overdo it. While it’s tempting to be cautious, too much lubrication isn’t a good thing. Excess grease traps dirt and restricts movement, creating new issues instead of solving existing ones.
Take steps to winter-proof equipment
Winter puts machinery to the test, but your bearings (and your facility) don’t have to suffer. A clear understanding of lubrication needs can help your equipment run smoothly through the winter months. A little extra maintenance also goes a long way in protecting your machinery against the pitfalls of moisture, friction, and other cold-weather stressors. It’s worth it for the peace of mind you’ll get during the harshest months of the year.
