Product Description
Unirex N greases are premium-quality, lithium-complex products suitable for high-temperature service in rolling-element bearings. These versatile greases can be used in a wide range of industrial applications and are particularly recommended for electric-motor lubrication.
Unirex N greases are not intended to be used under extreme pressure conditions where extra anti-welding properties are required.
Unirex N 2 meets the requirements of Lubricating Grease DIN 51825 - K2N - 20L and ISO L-XBDHA 2.
Features and 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.
Unirex N greases offer the following benefits:
| 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 |
Applications
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.
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.
