About the Airtac SE50 Standard Cylinder SE50X950
The AirTAC SE50X950 is a double-acting single-rod profile cylinder built to the ISO 15552 standard, delivering a push force of 982 N and a pull force of 825 N at 0.5 MPa. Its square extruded aluminum barrel eliminates external tie rods, creating a compact, corrosion-resistant body that mounts flush against machine frames while protecting internal components.
This 50 mm bore unit features a 950 mm stroke and a PT1/4 port. Because this specific SKU lacks the -S magnet suffix, it does not support the CMSE or DMSE electronic position sensors out of the box. Field-adjustable air cushioning at both ends allows technicians to tune end-of-stroke deceleration via a set screw, softening hard impacts during high-speed cycling.

Where the Airtac SE50 Standard Cylinder SE50X950 Is Used
Pallet Transfer Gate
Actuates a 950 mm diverter gate on a packaging line, using its 982 N push force to reliably redirect heavy filled pallets without tie-rod obstruction.
Textile Beam Lifter
Raises large textile warp beams into weaving looms, utilizing the long 950 mm stroke and adjustable pneumatic cushions to prevent jarring stops at full extension.
Sheet Metal Stacker
Elevates cut sheet metal blanks from a press discharge conveyor, where the flush aluminum profile resists lubricant buildup and the 825 N pull force retracts the carrier smoothly.
Is the Airtac SE50 Standard Cylinder SE50X950 the Right Cylinder?
When sizing this 982 N push class, stepping down to a 40 mm bore drops the output to 628 N, while stepping up to a 63 mm bore increases it to 1559 N at 0.5 MPa. Because this model carries a 950 mm stroke, the 20 mm piston rod and rod-end bearing face significant bending moments under side loads; an external guide rail is strongly recommended to prevent premature seal wear.
As a dimensionally interchangeable ISO 15552 cylinder, the SE50X950 serves as a direct drop-in replacement for other 50 mm profile cylinders on existing tooling. Note that a plain SE cylinder drifts when air pressure is removed or a valve centers; if your 950 mm stroke application must hold a vertical load safely without live pressure, integrate an external pilot-operated check valve or specify a BSE rod-lock variant.
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.
Airtac SE50 Standard Cylinder SE50X950 FAQ
At 0.5 MPa, the SE50X950 provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force is 1374 N, and the maximum push capacity is 200 kgf at 1.0 MPa. This 50 mm bore cylinder uses a PT1/4 port.
No, the standard SE cylinder will drift if air is exhausted or the valve is centered. The adjustable air cushioning only decelerates the piston near the stroke ends; it does not function as a brake. For position holding, consider a BSE rod lock variant or an external locking mechanism.
