Feature and Potential Benefits
Unirex N greases exhibit excellent high and low temperature performance, resistance to water and corrosion, and long service life in a range of bearing applications.
| Features | Advantages and potential benefits |
|---|---|
| Excellent high-temperature performance | Lithium-complex thickener resists softening / running out of bearings at temperatures up to 190°C |
| Outstanding grease life | Laboratory bearing rig tests show outstanding continuous lubrication performance at bearing temperatures of up to 140°C |
| Very good low-temperature characteristics | Start-up power requirements are low at temperatures down to at least -20°C. Meets DIN 51825 low temperature torque requirements at -20°C |
| Excellent mechanical stability | Exhibits excellent resistance to softening due to mechanical working |
| Excellent water and corrosion resistance | Resists water washout and protects bearings against corrosion |
| Excellent performance in high-speed applications | Channelling characteristics provide excellent performance in high- speed deep-groove ball bearings. Unirex N3 is recommended where DmN (mean bearing diameter X rpm) exceeds 360,000 |
Applications
UNIREX N 2 is an NLGI No. 2 grade and is preferred in most cases for application by hand-packing or by grease gun. UNIREX N 2 is recommended for the lubrication of electric motors. It is suitable for NEMA (National Electric Manufacturer's Association) Insulation Class A, B, and F motors.
UNIREX N 3 is an NLGI No. 3 grade and is used for special applications such as sealed-for-life bearings, vertically-mounted bearings, and higher-speed bearings.
Most of the uses for UNIREX N involve manual methods of application. Although UNIREX N 2 is suitable for use in automatic centralized systems, equipment served by these systems would normally not require the long-life properties of UNIREX N, since one of the functions of automatic systems is to replenish the lubricant at relatively short time intervals. UNIREX N 3 should not be used in such systems.
