Table 8.13 Lubricant quantities for grease lubrication – MG series
The lubricant quantities given below are reference values, which may vary depending on the ambient conditions.
NOTE
If the linear guideways are installed vertically, on the side or with the rail on the top, the relubrication quantities
must be increased by approx. 50 %.
NOTE
The removal of the existing lubricant is only necessary if the lubricants are not miscible.
NOTE
8.12 Changing lubricant
Before you change to a different lubricant, the entire block must be thoroughly cleaned. More information on this can be
found in Section 7.1.
