DERILL A631 Low Temperature Series Grease 

Product introduction 

DERILL A631 Ultra Low Temperature Series Grease is specifically for ultra-low temperature (below -40 ℃) condition of rolling bearing design of the rolling bearing, the grease is high quality, long life; DERILL A631 Ultra Low Temperature Series Grease adopts special grease thickeners thickening ratio of the total synthesis of base oil, and with the most advanced additive combination, through the use of advanced production technology and the most stringent test method,meeting the MIL - PRF - 81322 specifications. 

DERILL A631 Ultra Low Temperature Series Grease have excellent anti-wear protection performance and resistance to corrosion and anticorrosion performance. Synthetic base oil has excellent low temperature properties and natural high viscosity index to help improve the mechanical efficiency, achieving low starting torque and operating torque, and excellent low temperature pumping; Special thickener to keep the good mechanical stability and performance of grease, water resistance and structure stability performance, enable it to paly and keep the feature of contact in the bearing operation. 

DERILL A631 Ultra Low Temperature Series Grease advantages include prolonging the service life of the bearings, can be a be applied to - 60 ℃ conditions of rolling bearing.

performance characteristics 

★ Excellent oxidation stability; Compared with the traditional grease DERILL A631 Ultra Low Temperature Series Grease can maximize the extension of replacing grease intervals, and prolong the service life of bearing.

★ Outstanding performance at low temperature, Low starting torque in low temperature environment, excellent low temperature pumping.

★ Excellent anti-wear properties, four ball abrasion test: grinding spot diameter less than 0.36

mm.

★ It has good mechanical stability, keeping consistency during the replacement period of grease, preventing loss of grease, protecting the bearing effectively, so as to prolong the service life of bearing.

★ Excellent rust protection and corrosion resistance and wear resistance properties, reduce downtime and maintenance costs, achieving higher productivity.

★ Excellent water resistance, even in the case of with water vapor, it can maintain good lubrication performance.

★ Extremely low internal friction characteristics not only improve equipment mechanical efficiency, save energy, but also reduce the friction temperature rise.

★ Application temperature range is wide, equipment is easy to start when the temperature is below -40℃,When up to 150 ℃ ,it can still provide excellent protection.
