13 Lubrication

13.1

Notes

This section describes relubrication of the Linear Motion System by the customer.
The required relubrication by the customer is limited to the lubrication of the Profiled Rail System (FMS/FMB) and
the Ball Screw Assembly (FMS).
Basic lubrication takes place in-factory by the manufacturer.
Before using lubricants, read and observe the corresponding safety data sheets!
X
Do not use lubricants with solid particles (e.g. graphite or MoS
If you use different lubricants from the ones stated, you may find that relubrication intervals are shorter and that
performance decreases with short stroke and load ratio; in addition, chemical interactions may take place between
the plastics and lubricants.
In the case of relubrication, it is not possible to change from grease to oil lubrication.
If environmental factors such as contamination, vibrations, impact loads, etc. are present, we recommend reduced
relubrication intervals. Even under normal operating conditions, relubrication is required every two years due to
grease aging.
If other consumers are connected to the single-line lubrication system, the weakest link in this chain determines
the lubrication cycle.
Excess lubricant can accumulate inside of the module or flow out and may lead to contamination of the
environment.
NOTICES
Insufficient lubrication
Never put a Linear Motion System into operation without having carried out basic lubrication.
f
Overlubrication
Increased coefficients of friction resulting in increased temperature generation in the Ball Screw Assembly and
the Ball Rail Systems.
Do not significantly overlubricate the Linear Motion System.
f
Risk of insufficient lubrication due to use of wrong lubricants!
Damage to the product.
Use only the recommended lubricants.
f
Risk of property damage due to insufficient lubrication!
Loss of performance and corrosion.
Observe the lubrication intervals.
f
Avoiding pressure peaks due to excessive speed after lubrication
Damage to the product
Proceed slowly (< 0.5 m/s) immediately after lubrication.
f
Performance altered by special operating conditions!
Damage to the product.
Before starting up the product under special operating conditions, please consult Bosch Rexroth AG. This
f
applies especially to environments with glass fiber or wood dust, solvents, extreme temperatures, and for
short-stroke applications.
