The lubrication of the inner transmission devices to the casing is made, in the series production, using a synthetic oil having marked tribologic characteristics: UNIMEC ATIR SH150. The technical specifications and the application field for the lubricant inside the casing are shown below.

* for operating temperatures 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.

BALL SPINDLE
The end user is responsible for the lubrication of the ball spindle which must be carried out using a lubricant suggested by the manufacturer.Lubricating the ball spindle is an important and determining factor for the proper functioning of the screw jack. It must be carried out at regular intervals that can assure a constantcoat of clean lubricant between the contact parts.

Insufficient lubrication, 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 ball spindles are covered by protections it is necessary to periodically verify the lubrication conditions.
