Solid Lubrication Bearing for Food and Beverage Machinery

MTWB Solid Lubrication Bearings are engineered specifically for food and beverage processing applications where conventional lubrication is difficult, impossible, or uneconomical. Designed with embedded solid lubricants and polymer matrix adsorption technology, these self-lubricating bearings provide reliable, maintenance-free performance under high loads, low speeds, high temperatures, and demanding sanitary conditions.

MTWB helps OEM manufacturers and food processing facilities improve equipment reliability, reduce maintenance costs, and extend service life through application-specific bearing solutions.

Technical Specifications

Lubricating oil (grease) content: 40% – 95%

How It Works

The polymer material is injected into the bearing through a specialized process. The polymer adsorbs saturated lubricating oil, ensuring continuous contact with raceways and rollers while effectively preventing contaminants from entering the bearing interior.Lubricating oil is "stored" in the micro-pores within the polymer based on surface tension. During operation, a small portion of the lubricating oil slowly moves to the material surface through capillary action; when operation stops, the oil re-adheres to the polymer for "storage".

Key Advantages

✓ Lifetime Maintenance-Free

With polymer matrix adsorption saturated lubricant technology, lubricant seamlessly adheres to the raceway and rolling elements without the need for an external oil supply system. Re-greasing is completely eliminated. The embedded sealing design effectively prevents pollutant invasion, improves water flushing resistance by 80%, and significantly reduces the risk of downtime caused by lubrication failure.

✓ Extended Service Life

Solid lubricant content is 2–4 times higher than traditional lubricants. Bearing service life can be extended by more than 3 times, significantly reducing the frequency of spare parts replacement.

✓ Contamination Prevention

Solid lubricant maintains close contact with raceways and rollers, almost completely filling the bearing interior. The remaining space effectively prevents pollutants from entering, protecting the bearing from contamination.

✓ Zero Lubricant Leakage

Lubricating oil is stored in the micropores inside the polymer based on surface tension.During operation, oil is transferred to the material surface under capillary action; when operation stops, oil is reabsorbed into the polymer for "storage," preventing environmental pollution caused by lubricant leakage.

✓ Clean and Hygienic Operation

Solid lubrication bearings are suitable for high ambient temperatures (up to 200℃), high humidity, dusty, and chemical corrosion environments.The design keeps oil contained within the bearing with an integral seal, further improving oil retention.

✓ Superior Washdown Resistance

Solid lubricants support integral seals and provide excellent anti-rinsing capability, critical for food processing environments that require frequent high-pressure washdowns.
