8.2.3 Lubricating the linear guide and the drive elements
The ball screw axis is lubricated with grease from an internal reservoir.
The reservoir is factory-prefilled. The carriage features 3 grease nipples
at each side for relubrication.
• The outer grease nipples are used to lubricate the linear guide.
• The inner grease nipples are used to fill the drive element (ball
screw drive).
The lubrication interval depends on the load, the velocity, the cycle time
and the ambient conditions. The following recommended values apply to
lubrication intervals:
Linear guide • 5000 km operational performance
Drive elements • 100 km at a screw pitch of 5 mm
• 200 km at a screw pitch of 10 mm
• 400 km at a screw pitch of 16 mm
See chapter 7 "Accessories and spare parts" for grease guns, nozzles
and lubricants.
Notes on greasing When applying the lubricant, you must not exceed a maximum flow rate.
Therefore, the minimum injection time of 3 seconds per grease gun
stroke must be adhered to.
The carriage must be moved between strokes of the grease gun to allow
the grease to distribute evenly in the lubricant reservoirs.
