Long-Term Lubrication Solutions
Bearings With Molded Oil
NSK Molded-Oil bearings represent a breakthrough in lubrication technology, utilising an oil-impregnated material—Molded-Oil—that consists of lubricating oil and oil-related polyolefin resin. This specialized material slowly releases lubricant over long periods, providing sufficient lubrication without the need for constant relubrication. These bearings are specifically engineered for maintenance teams and engineers operating in water- and dust-contaminated environments, such as food processing, papermaking, and steel mills. Corsair Sarl is a leading supplier of high-quality NSK Molded-Oil bearings, providing expert support and fast Swiss delivery to ensure your machinery operates with maximum efficiency and minimal environmental impact.

Applications and Use
Molded-Oil bearings are ideal for environments where traditional grease lubrication fails or causes contamination issues.
Nahrungsmittelindustrie (Food Industry)
Clean, eco-friendly operation with minimal oil leakage
Water & Dust Exposure
Conveyors, agricultural machinery, and cleaning lines where water can wash out standard grease
High-Technology
Semiconductor and liquid crystal display manufacturing
Heavy Industry
Steel mills and paper manufacturing
Note
While resistant, if the bearing is directly exposed to water for long periods, additional seals are recommended to prevent oil washout

Standards, Naming, and Identification
How to identify your bearing
- Basic Code: Standard bearing reference (e.g., 6205).
- Molded-Oil Symbol:
- L11: For general applications.
- L12: For high-speed applications.
- Suffixes: DDU (Seals), ZZ (Shields), CAM (Machined brass cage), EA (Pressed steel cage).
Example Identification Checklist
- Lagerbezeichnung: 6205.
- Molded-Oil Type: L11 (General use).
- Sealing/Material: DDU (Rubber seals).
Materials and Variants
Standard Wälzlagerstahl (Bearing Steel)

FAQ
What is the temperature range for Molded-Oil bearings?
They are recommended for ambient temperatures up to 80°C (176°F). High-speed L12 variants are better suited for higher ambient temperatures within the range.
Can I use these bearings in a vacuum?
Not specified in the provided documentation.
How much longer do they last than grease bearings?
Tests show they last min. 50 days compared to 20 days for grease bearings in water-exposure tests—a 2.5x increase.
Are stainless steel versions available?
Yes, deep groove ball bearings are available in stainless steel (Rostfreier Stahl) with the -H-20 suffix.
Can they be used at high speeds?
Yes, but you must select the L12 variant specifically designed for high-speed operation.
