Inner lubrication
The lubrication of the inner transmission devices to the casing is made, in the serial production, using a long lasting grease: TOTAL MARK CA. It is an extreme pressure lubricant based on calcium sulfonate. For size 183, on the contrary, the TOTAL MULTIS MS 2 is used, which is a calcium-soap grease, suited for extreme pressures as well. In any case a plug is foreseen for all sizes (except for 183) in case of lubricant filling up. The technical specifications and the application field for the lubricant inside the casing are listed below.

* for operating temperatures included between 80°C and 150°C Viton^® seals should be used;
for temperatures higher than 150°C, and lower than -20°C, it is advisable to contact our Technical office.

The threaded spindle
The end user is responsible for the lubrication of the threaded spindle which must be carried out using an adhesive lubricant, addicted for extreme pressures:

* for operating temperatures included between 80°C and 150°C Viton^® seals should be used;
for temperatures higher than 150°C, and lower than -20°C, it is advisable to contact our Technical office.

Lubricating the threaded spindle is an important and determining factor in the proper functioning of the screw jack. It must be carried out at regular intervals that can assure a constant coat of clean lubricant between the contact parts. Insufficient lubrication, the use of an oil without extreme pressure additives or an improper lubrication can lead to abnormal overheating and consequent wear phenomena, which naturally reduce the operating life of the screw jacks. In case the screw jacks are not visible or the threaded spindles are covered by protections, it is necessary to periodically verify the lubrication conditions. For heavier duties than those showed in the relative graphs it is recommended to contact our Technical office.
