Mobil / ESSO UNIREX N2
UNIREX N 2 in an NLGI No. 2 grade and is preferred in most cases for application by hand packing or by grease gun.
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. 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.
UNIREX N 3 meets the requirements of Lubricating Grease DIN 51825 - K3N - 20L and ISO L-XBDHA 3.
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.
• 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

Mobil / ESSO 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.
Key applications include:
• Electric Motors
• Refridgeration Compressors
• 400g Cartridge
• 5 Litre
• 20 Litre Pail
