Mobil As graxas Unirex são produtos de alta qualidade adequados para uso em temperaturas elevadas em rolamentos de corpos rolantes. Esses lubrificantes de complexo de lítio podem ser usados em diversas aplicações industriais; em particular eles são ideal para lubrificação de motores elétricos.
Unirex N3 is a grease with an NLGI No. 3 consistency grade. This Mobil product is often used within specific applications like electric motor bearings that are permanently sealed or vertically mounted, as well as extreme speed applications. These greases are not, however, suited to use in those conditions of extreme pressure that would normally require additional anti-welding characteristics.
Mobil Unirex N3 has a solvent-refined mineral oil base, and the formula includes a tailor made lithium complex thickener. This grease complies with Lubricating Graxa DIN 51825 – K3N – 20L and ISO L-XBDHA 3.
Mobil Unirex N3 features and benefits
A range of key features and benefits make Mobil Unirex N3 a favoured product within industry. Some of the main advantages of its use can be outlined as follows.
Excelente desempenho em temperaturas elevadas
Mobil Unirex N3 has been formulated to include a lithium-complex thickener. This offers resistance to the running out and softening of bearings that can occur. As a result of this unique feature, the grease is capable of operating to an exceptional standard, even where temperatures may reach a maximum of 190°C.
Desempenho em baixas temperaturas
This grease doesn’t only offer an impressive performance in high temperatures: Mobil Unirex N3 can also deliver superb results when used in low temperature operations. This particularly applies to cold start-up, as the lubricant may be used when the temperature reaches as low as -20°C. The reduced temperature torque requirements of DIN 51825 are therefore capably met where this grease is used.
Resistência a corrosivos, água e formação de depósitos
O lubrificante oferece resistência superlativa à matéria aquosa e também aos corrosivos. Isto leva a níveis muito mais baixos de lavagem com água. Os rolamentos também são protegidos contra corrosão, além de serem protegidos contra depósitos e acúmulo de lama. O efeito disto é uma redução no tempo de inatividade da máquina para manutenção e reparo, o que pode levar a economias em termos de custos e também de tempo.
Vida útil prolongada do lubrificante
Rigorous testing has shown Mobil Unirex N3 to provide an exceptional level of continuous lubrication. This applies even where bearing temperatures reach up to a maximum of 140°C. This has been proven by means of a series of bearing rig tests.
Adequação para aplicações de alta velocidade
Specific characteristics of this grease are put to use during high-speed applications, where it has proved to be an outstanding performance product. A typical example is applications that utilise deep groove ball bearings. Mobil Unirex 3 is also the perfect grease to use when more than 360,000 bearing diameter X rotations occur per minute.
Principais aplicações
Mobil Unirex N3’s key recommended application is electric-motor lubrication. However, the incredible versatility of this grease makes it useable for a range of applications, especially in industrial environments. This lubricant can also be highly effective when used, for example, in conjunction with vertically mounted and sealed-for-life bearing systems.
