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|
