About the Airtac SE50 Standard Cylinder SE50X900S
The AirTAC SE50X900S is a double-acting, single-rod ISO 15552 profile cylinder engineered for a 900 mm stroke. It features a square extruded aluminum barrel without external tie rods, yielding a compact, corrosion-resistant body that mounts flush within tight machine envelopes. Delivering 982 N of push force at 0.5 MPa, it is tailored for long-travel linear positioning tasks.
Equipped with a built-in magnet (-S), this unit supports AirTAC CMSE reed and DMSE electronic sensors for precise end-of-stroke detection. The field-adjustable pneumatic cushioning at both ends allows technicians to tune end-cap deceleration via a set screw, softening hard mechanical stops during high-velocity 30-800 mm/s cycles.

Where the Airtac SE50 Standard Cylinder SE50X900S Is Used
Pallet Transfer Line
Pushes heavy pallets along a 900 mm accumulation conveyor segment, utilizing the 982 N push force to overcome cart friction at 0.5 MPa.
Film Roll Web Handling
Actuates a 900 mm stroke cutoff and splicing mechanism on a continuous packaging line, relying on DMSE electronic sensors for timing.
Lab Sample Indexing
Moves test tube racks between processing stations over a 900 mm span, benefiting from the adjustable cushion to protect delicate glassware.
Is the Airtac SE50 Standard Cylinder SE50X900S the Right Cylinder?
Generating 982 N push at 0.5 MPa, this 50 mm bore fits mid-range actuation needs. If your assembly requires less force, the 40 mm bore provides 628 N push; stepping up to the 63 mm bore yields 1559 N push for heavier payloads. Because this is a standard double-acting cylinder, it will drift if air pressure is lost or a valve centers—use a BSE rod lock for fail-safe holding.
At 900 mm of travel, the 20 mm rod and M16x1.5 thread face significant bending moments under side loads. Mounting an external guide rail is strongly recommended to prevent rod-bearing wear. As a dimensionally interchangeable ISO 15552 cylinder, it serves as a drop-in replacement sharing standard mounting accessories, a PT1/4 port, and the -S magnet footprint.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for CMSE/DMSE sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (LB/FA/FB/CA/CB/CR/TC/FTC/TCM1/TCM2).
- check Installation by qualified personnel per AirTAC docs.
