Screw Jacks are normally suitable for operation at ambient temperatures of up to 90°C. Operations above 90°C will require special lubricants. For temperatures above 90°C, the life of even special lubricants is limited. Therefore consult Power Jacks on your application. For temperatures above 90°C, advise Power Jacks of full particulars of the duration of such temperatures. In some cases, it may be necessary to furnish an unlubricated unit, then the customer can supply the lubricant of his own choice. Power Jacks suggest that a lubricant manufacturer be consulted for type of grease and lubrication schedule. As a general rule, the screw jacks unit should be shielded to keep ambient temperatures to 90°C or less.

Seals for temperatures above 120°C are expensive. Instead, Power Jacks can substitute bronze bushings for seals in these cases. If bellows boots are used, special materials will be required for temperatures above 90°C. Power Jacks can manufacture special screw jacks for high operating temperatures above 120°C. Consult Power Jacks Ltd on an application basis.

Power Jacks have manufactured products that can operate at temperatures up to +250°C.
