Castrol Molub-Alloy 243 Arctic Low temperature grease 400g cartridge

Castrol ​Molub-Alloy 243 Arctic Low temperature grease

Molub-Alloy™ 243 Arctic Grease is intended for use in plain and anti-friction bearings operating in freezing environments down to -65°F (-54°C). It is designed to meet the performance requirements of MIL-G-10924C Specification.
For effective lubrication in very cold temperatures, a primary requirement of grease is that it remain soft and pliable, especially in rolling element bearings. Stiff grease in anti-friction bearings can prevent rolling at start-up or allow skidding during operation, possibly resulting in damage and early failure.
Of equal importance for greases in very cold regions is the ability to protect against corrosion. As temperatures drop from daytime operation to overnight freezing, moisture from the air is precipitated an the cooling metal surfaces. Bearings experiencing wide temperature fluctuations are particularly subject to corrosive attack.

Application

May be used as a multi-service lubricant through the broad range suggested by MIL-G-10924C as from -65°F (- 54°C) to 225°F (79°C).
Applications include journal bearings as well as antifriction bearings found in pumps, motors, conveyors, etc.
Common applications are in transportation and material handling equipment, whether in arctic regions or in refrigerated areas in general industry.
Applications at low temperatures should be made manually. Automatic dispensing equipment may be used at higher temperatures, as with greases of similar consistency. If automatic dispensing below 0°F (-18°C) is necessary, or extreme pressure characteristics are required, CASTROL Molub-Alloy 333 EP Light Arctic Grease may be suggested. (See Notes)

Specifications / Approvals

• MIL-G-10924C

Advantages

• Maintains good working and staying consistency over suggested use range.
• Excellent protection against corrosion in presence of condensing moisture.
• Substantial increase in the service life of both parts and lubricant will result from the proper establishment of a protective layer of Molub-Alloy solids. These lubricating solids can effectively increase the load bearing area, thus reducing unit pressures and wear.
• Realistic energy savings are possible through a reduction in peak power demand during cold startup.
• Overall savings are derived from the above and result from less labor and downtime, smoother, more efficient operation with longer parts life, and extended lubrication cycles.
