Description
MOBIL 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.
MOBIL UNIREX N greases are not intended to be used under extreme pressure conditions where extra anti-welding properties are required. MOBIL UNIREX N 3 meets the requirements of Lubricating Grease DIN 51825 - K3N - 20L and ISO L-XBDHA 3.
Applications
- Most of the uses for MOBIL UNIREX N involve manual methods of application.
- Although MOBIL 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 MOBIL UNIREX N, since one of the functions of automatic systems is to replenish the lubricant at relatively short time intervals. MOBIL UNIREX N 3 should not be used in such systems.
Features and Benefits
Mobil 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.
- 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
