UNIREX N 3 is an NLGI No. 3 grade often used for special applications such as sealed-for-life electric motor bearings, vertically mounted bearings, and higher-speed 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 |
