Piping
Piping should be of a rust resistant material and be of a sufficient
internal area for piston speed required. Make sure that piping is clean
and free from sealing compound before connecting to system.
End Port Piping
Refer to Figure 7 to determine when end port piping can be used with
various types of mountings relative to fitting clearance.

On all bore sizes with axial foot mounting (LB or LB1), the end port
pipe fittings will obstruct the mounting holes. To avoid this problem,
mount the cylinder first and tighten the mounting bolts and then attach
the pipe fittings to the cylinder ports.
Cushion Adjustment
Cushion adjustment screws are located next to the ports on the side of
the cylinder. The cushion effect can be reduced by loosening the
cushion screw (turning counterclockwise). If the cylinder is subjected
to high kinetic energy due to a heavy load or high speed, etc., an
external cushion device should be considered to absorb the kinetic
energy load. See stroke adjustment and shock absorption option.
Quality of Compressed Air
Use clean, dry compressed air to operate the cylinder. This can be
accomplished by installing a filter with a proper filtration rating and
flow rate ahead of the directional control valve and draining the filter
regularly to ensure that no moisture or contaminants are allowed into
the system.
Work Environment
System components should be mounted in areas free from corrosive
atmosphere, rain, water and direct sunlight. If cutting oils, coolants, oil
mists, etc. are present, the cylinder should be covered or protected to
avoid damage to the seals. Also, avoid areas where cutting chips, dust,
spatter, etc. will come in contact with the cylinder.
Under normal usage, the cylinder has an effective dust-seal belt which
prevents contamination from entering the interior of the cylinder.
However, under unusually dusty or contaminated operating conditions,
it is recommended that the cylinder be mounted with the work table and
dust-seal belt facing down. When mounted in this fashion, be sure to
check the weight deflection chart to ensure that the unsupported tube is
not overloaded. C-mounts are available for use in these circumstances.
See pages 14 and 15 for C-mount dimensions.
External Guides
When external guides are employed, ensure that excessive forces are
not transmitted to the cylinder due to friction, misalignment, or
deflection of the external guides. Use of a floating joint is
recommended. See pages 28-31 for application forms and pages 14
and 15 for floating joint dimensions.
Other Considerations
Avoid electric welding around the rodless cylinder as current could be
conducted through the cylinder tube and destroy the dust belt.
Excessive inertia will cause the cylinder to malfunction. Ensure that
inertia loads are within allowable range.
Deep scratches or dents on the cylinder tube from external means may
have an effect on cylinder performance.
If negative pressure (vacuum) is caused in the cylinder by excessive
external force or inertia force, the pressure seal belt may be drawn
away from the slit tube causing external leakage. Ensure that no
negative pressure or vacuum can be generated inside the cylinder.
