Low temperature grease with solid lubricants Description Castrol Molub-Alloy 243 Arctic grease is intended for use in plain and rolling bearings operating at temperatures down to -55°C. It is designed to meet the performance requirements of the MIL-G-10924C specification. For effective lubrication at very low temperatures, the most important requirement is that the grease remains soft, especially in rolling bearings. Stiff lubricating grease in rolling bearings prevents the rolling movement when starting or even causes the rolling elements to slide during operation, which may destroy the bearings. Corrosion protection is equally important for low-temperature greases. Due to the temperature fluctuations from higher operating temperatures during the day to low temperatures during the night, the air humidity is reflected on the cold metal surfaces . Under these circumstances, the risk of corrosion is particularly high.
