Chapter: Maintenance
5-4 M10-16250-EN
The following areas of the machine will require periodic lubrication:
• Ballscrews - The ballscrews are lubricated via a ballnut that is located on the crosshead
where the ballscrew intersects the crosshead. As the crosshead moves up and down, the
ballnut disperses a thin layer of lubricant over each ballscrew as the ballscrew passes
through the ballnut. Periodically, the ballnut must be filled with lubricant to ensure that
the ballscrews remain well lubricated. The ballnut must be maintained and filled in
accordance with Table 5-1 on page 5-3.
Inspect the ballscrew and lubricate more frequently if any of the following conditions
exist:
• There is high-load or high-speed testing.
• There is long-term, continuous movement of the crosshead.
• The system operates in a dirty environment.
• There are high-load cycling tests.
• Guide columns - The guide columns require only a thin film of lubrication. It is
recommended that the machine be re-lubricated every two years.
• Mounting surfaces - as mentioned in the Cleaning section, the mounting area in the
base of the floor models must also be lubricated if it is regularly exposed (no base
adapter installed). Use a lint-free cloth and the same lubricants and schedule used for the
ballscrews and guide columns.
The top and bottom ballscrew bearings are sealed and should never need lubrication.
