Environmental factors

• Our products are resistant to many media that are commonly found in
manufacturing, such as water, mineral oil, grease and detergents. Contact your
Rexroth representative if you have any doubts about resistance to specifi c
chemicals, such as test oil, doped oils, aggressive cleaning agents, solvents or
brake fl uid.
• Avoid prolonged contact with highly reactive acidic or alkaline materials.
• Contamination can greatly increase wear – specifi cally from abrasive media
from the surrounding area, such as sand and silicates, e.g. from construction as
well as machining processes in the transfer system (e.g. welding beads, pumice
powder, glass shards, chips, waste parts, etc.). Maintenance intervals should be
signifi cantly shortened under these circumstances.
• Resistance to media and contamination does not mean that functional safety is
guaranteed in every case.
– Liquids that thicken as they evaporate and become highly viscous or adhesive
(sticky) can lead to malfunctions.
– If they get carried onto systems with rollers, media which have a lubricating effect
can lead to a reduction in the drive power that is transmitted via friction.
In such instances, special care must be taken when planning the system, and the
maintenance intervals must be correspondingly shortened.
