Molded Oil™- Bearings

Product catalog summary

Introduction to Molded-Oil™ Bearings
NSK has developed Molded-Oil™ Bearings, which use an oil-impregnated material combining lubricating oil and polyolefin resin. This design ensures prolonged lubrication and is suitable for various industrial applications.

Features and Benefits

Performance in Contaminated Environments: Effective in water and dust-laden environments, preventing liquid and dust ingress.
Environmental Friendliness: Minimizes oil leakage due to controlled lubricant release.
Low Torque and High-Speed Operation: Special treatments and optimized compositions allow for smooth and high-speed operations.

Applications

Steel and paper mill equipment
LCD and semiconductor manufacturing
Agricultural and food processing machinery
Cleaning and conveying equipment

Product Specifications

Types: Spherical roller bearings, deep groove ball bearings, and tapered roller bearings.
Model Numbers: Variations for general use (L11) and high-speed operation (L12).
Handling Precautions: Avoid heating above 100ºC and exposure to corrosive substances.

Performance and Testing

Durability: Outperforms grease-lubricated bearings in water exposure tests, lasting significantly longer.
Testing Conditions: Tested under water exposure with specific rotational speeds and loads.

Conclusion
Molded-Oil™ Bearings by NSK offer a reliable and environmentally friendly solution for various industrial applications, providing excellent performance in challenging environments.

Test Conditions and Specifications
Bearings Tested: 6305DDU
Radial Load: 98 N
Axial Load: 245 N
Rotational Speeds: 3,500 min–1, 4,200 min–1, 4,600 min–1

Durability Test Results
At 4,600 min–1, the test was aborted after a 200-hour torque increase. At 4,200 min–1, the test continued after 2,000 hours. At 3,500 min–1, the test was aborted after a 500-hour torque increase, with a possibility of continuation after 5,000 hours.

Bearing Torque Comparison
Comparison between grease-lubricated and Molded-Oil™ bearings shows stability for both general use and high-speed operation. Torque ratio is 1.00 when the bearing torque is stable under grease lubrication.

Additional Test Conditions
Deep Groove Ball Bearings (6305DDU): Rotational Speed: 1,200 min-1, Radial Load: 29.4 N, Axial Load: 29.4 N. Spherical Roller Bearings (22311 CAM): Rotational Speed: 800 min-1, Radial Load: 2.744 N, Axial Load: 294 N.

Molded-Oil Bearings Molded-Oilٙ Bearings are lubricated with NSK's own oil-impregnated material Molded-Oil - which consists of lubricating oil and polyolefin resin that has an affinity for oil. Lubricant slowly seeping from this material provides ample lubrication to the bearing for extended periods. Features of Molded-Oilٙ Bearings > Excellent performance in water- and dust-contaminated environments The bearings are designed to prevent liquids such as water (which can wash the lubricating oil out) and dust from getting inside the bearings. Sealed types can be used in environments exposed to...
