Mobil Unirex N 2, 400gr

Mobil Unirex N 2

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. 

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.

Applications:

Because of their outstanding oxidation stability and resistance to softening at high temperatures, UNIREX N greases may be used in many applications such as oven-conveyor bearings, dryer-roller bearings, rotary steam joints, kiln-car bearings, induced-draft fan bearings, and equipment adjacent to high radiant heat such as ovens, soaking pits, etc. 

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. 

Regardless of the level of oxidation stability of a grease, an increase in temperature will affect the rate of oxidation and thermal deterioration. Consequently, more frequent relubrication is required at higher temperatures. For UNIREX N greases, it is recommended that relubrication intervals not exceed one week of continuous service at 175°C. As temperatures approach 190°C, relubrication intervals should be daily or every shift. Relubrication intervals will, of course, vary widely with the type of service and should be based primarily on the recommendations of the motor manufacturer.
