3 Molded Oil Bearings NSK Molded Oil Bearings is a solid lubricant mixture of polymers, oils, and other additives which can be customized for your specific lubrication requirements. NSK s solid lubricant has an oil-filled, connected, porous structure. The porous polymer structure fills the air space between the rolling elements and race, keeping foreign objects out while retaining oil in the pores. The oil lubricates the bearing surfaces by capillary action. Additional oil is supplied to the bearing from the reserves in the pores. There is no need for maintenance or additional lubrication during the life of a NSK Molded Oil filled bearing. Product Benefits -Reduce maintenance costs and down time. -Keep contaminants out of bearing. -Extend bearing life. -Improve housekeeping by eliminating the dripping of grease and oil. -Are available in several formulations, including H-1 and H-2 formulas which meet applicable USDA and FDA standards L11 1 C E4 C3 Bearing Type Solid Lube Type 1: standard 8: low temperature 4: heavy load, low speed A: high speed 5: high temperature 6: high temperature (wash down application) B: food grade 7: food grade (higher load viscosity oil) Clearance Lube Feature Cage L11-6 high temperature (wash down application) L11-6- is designed for high temperature wash down applications.

5 Graphite Solid Lube Bearings NSK Graphite Solid Lube is a dry, solid graphite formula engineered to seal and lubricate bearings and conveyor wheels. It exhibits extraordinary performance even in the most difficult applications. It is the only product that works at hightemperatures (350 0 C) and low temperatures (-65 0 C) without any change in torque and without the need for seals or shields to keep the lubricant in the bearing. Application: Baking Conveyer Product Benefits -*Can be used submerged in most chemicals (even mild acid or alkali) it will not dissolve. - Is resistive to deterioration due to radiation or UV. - Improves housekeeping by eliminating the dripping of grease and oil. - H as virtually no outgassing when used in vacuum applications even at high temperatures. - Keeps contaminants out of bearing. - Increases bearing life and eliminates periodic maintenance L1 Bearing Type Solid Lube Graphite Solid Lube L11 G C E4 C3 Clearance Lube Feature Cage Graphite Solid lube is available on various bearings Food and Beverage industries 5

11 Innovative products for increased productivity Aqua-Bearings NSK Aqua-Bearings use a special fluororesin for the inner and outer rings, as well as for the cages. These bearings are perfect for a whole string of applications with water, alkali and acid environments. They manage without the usual grease or oil lubrication. Chrome-plated corrosion-resistant bearings Thanks to nickel-plating, these bearings display an extremely high resistance to corrosion. Even constant underwater operation cannot adversely affect their performance. Corrosion-resistance through nickel-plating These bearings can withstand chemical washing processes and represent a cost-effective alternative to totally ceramic bearings. They are suitable for alkaline and mildly acidic environments as well as for applications with water rinsing. Triple-lip sealed inserts Triple-lip sealed inserts can replace ordinary ball bearing inserts in applications where bearings are subjected to strong dust or water pollution, such as in vegetable washing plants or in fish processing plants.
