10.1 Information on operation

10.1.1

Wear

• Individual components are subject to unavoidable wear by their very nature.
Constructive measures and the selection of materials help ensure functional
reliability over the full service life. However, wear is also dependent on
the operating, maintenance and ambient conditions at the place of use
(resistance, contamination).
• Overloading the conveyor sections can cause the conveyor medium to malfunction
and lead to the premature breakdown of motors and gears.
• If hydraulic/pneumatic activated components are overloaded, it is not possible to
guarantee their function.
• Overloading of hydraulic components can lead to leakage and component failure.
10.1.2

Measures to reduce wear

The following obvious measures will reduce wear:
• Switch off the conveyor section during line downtime, e.g. during breaks, at night
and on weekends.
• Do not select a higher speed for the conveyor section than that required for the
corresponding function.
• Avoid contamination caused by abrasive media, reduce contamination by cleaning
on a regular basis.
• Set pressure switch and pressure relief valve as low as necessary for the function.
• Select the duty cycle and stopping time as low as possible.
10.1.3

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.
