SOLID LUBRICATION BEARINGS: BUILT-IN RELIABILITY WHERE GREASE FAILS
Traditional grease and oil work until they don’t. Washdowns, humidity, dust, vibration, temperature swings, and missed maintenance intervals all push conventional lubrication to its limits. Solid-lubricated bearings eliminate these risks by locking lubrication inside the bearing for consistent, long-term performance.
WHAT IS SOLID LUBRICATION?
Solid lubrication is an innovative bearing technology that replaces conventional grease with a polymer matrix saturated with lubricating oil. This polymer is molded directly into the bearing's cavity, filling the space around the rolling elements without impeding their movement.
WHAT SOLID LUBE DELIVERS
Solid-lubricated bearings are lubricated for life. There is no re-greasing, no oil migration, and no dependency on maintenance schedules. Once installed, lubrication is no longer a variable. Solid lube provides the bearing with an even, consistent film of lubrication. When the operating temperatures increase, oil is “pushed” toward the surface of the polymer. During shutdown or when temperatures return to normal, the oil is reabsorbed back into the polymer material.
Clean, Controlled, and Contained: The lubricant stays exactly where it belongs. No dripping, slinging, or washout. This makes solid lube ideal for applications where cleanliness, safety, and environmental exposure matter.
Consistent Performance Over Time: Solid lube provides a steady, controlled release of lubricant to the rolling elements. The result is smoother rotation, stable torque, and reduced noise throughout the bearing’s service life — not just at startup.
Reliability in Harsh Environments: High humidity, frequent washdowns, airborne contamination, vibration, or temperature swings don’t strip the bearing of lubrication. Solid lube keeps working when grease breaks down. Solid lube cannot be washed out, and all free space within a bearing is filled, meaning contamination is limited. Solid lube also supports seals in these wet applications.
Increased Lubricant Life: Studies have shown that a bearing that has solid lubrication contains 4X more oil than bearings that have conventional grease.
Extended Equipment Life: The solid lube acts as a secondary seal, protecting against contaminants, water, and dust, which minimizes wear and extends bearing longevity.
Superior Oil Retention: With up to 4X more oil capacity, it ensures consistent lubrication, even in start-start or low-speed applications.
Reduction in Cost of Ownership: With the increased lubrication life in wet environments, this will reduce the overall cost of ownership and reduce environmental impacts.
WHERE SOLID-LUBRICATED BEARINGS MAKE THE MOST SENSE
Washdown Environments
• Food & beverage processing equipment
• Bottling and packaging lines
• Meat, poultry, and dairy processing
• Pharmaceutical washdown areas. Solid lube prevents grease washout and water intrusion, extending bearing life where traditional lubrication fails quickly.
Conveyors & Automated Systems
• Packaging conveyors
• Assembly automation
• Sortation and material handling systems
• Hard-to-reach or remote machinery. Ideal for bearings that are sealed, enclosed, or difficult to access once installed.
•Industrial & OEM Equipment
• Fans and blowers
• Small motors
• Pumps and auxiliary equipment
• Equipment in extreme temperature settings. Improves reliability while reducing total cost of ownership for OEMs and end users alike.
Medical & Cleanroom Equipment
• Medical devices and lab automation
• Diagnostic and imaging equipment
• Cleanroom automation: No lubricant migration, no contamination risk, and no maintenance interruptions. The environment remains clean, and hygiene standards are met.
Outdoor & Environmental Exposure
• Weather stations and anemometers
• Agricultural sensors and controls
• Solar tracking systems
• Traffic and monitoring equipment
• Marine vessels
• Port cranes. Solid lube eliminates concerns about rain, humidity, temperature cycling, and long periods without maintenance.
WHY CUSTOMERS CHOOSE SOLID LUBE
• Fewer bearing failures caused by improper lubrication
• Less downtime and fewer emergency maintenance calls
• Reduced labor and maintenance costs
• Cleaner equipment and safer work areas
• Predictable performance over long service intervals
• Bearing life and reliability increased
• Bearings lubricated for life
• Reduced environmental impact. While solid-lubricated bearings may carry a higher initial cost, customers quickly recover that investment through reduced maintenance, longer service life, and improved system reliability.
THE BOTTOM LINE
If lubrication access is difficult, the environment is harsh, or downtime is expensive, solid lubrication isn’t a luxury. It’s a smarter engineering choice. Solid-lubricated bearings turn lubrication into a built-in advantage instead of a recurring problem. Solid lubrication represents the future of efficient, reliable machinery. By choosing solid lubrication, you are not just lubricating; you are optimizing for peak performance and profitability.
