Mobil Unirex N 3
High Temperature Bearing Grease
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.
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.
Mobil Unirex N greases are not intended to be used under extreme pressure conditions where extra anti-welding properties are required. Additionally, Mobil Unirex N 3 meets the requirements of Lubricating Grease DIN 51825 – K3N – 20L and ISO L-XBDHA 3.
Main Applications of Mobil Unirex N 3
Mobil Unirex N 3 is recommended for the lubrication of industrial electric motors. It is suitable for NEMA (National Electric Manufacturer’s Association) Insulation Class A, B, and F motors.
As a long-lasting, high temperature bearing grease, most of the uses for Mobil Unirex N involve manual methods of application.
Although Mobil Unirex N is suitable for use in automatic centralised systems, industrial 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 industrial lubricant at relatively short time intervals. Mobil Unirex N 3 should not be used in such systems.
Benefits and Features of Mobil Unirex N 3
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.
