About the Airtac SE50 Standard Cylinder SE50X700H
The AirTAC SE50X700H is a double-acting single-rod profile cylinder built to the ISO 15552 standard, delivering a robust 982 N push force at 0.5 MPa. Its square extruded aluminum barrel eliminates external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames. This 50 mm bore unit incorporates a high-temperature FKM (Viton) seal, extending the operating window up to 150 C for demanding thermal environments.
This 700 mm stroke model relies on field-adjustable pneumatic cushioning at both ends to decelerate the piston smoothly before end-of-travel impact. Because this specific SKU lacks the -S magnet suffix, it does not support direct CMSE or DMSE position sensing without modification. The FKM seal also ensures reliable low-friction cycling when exposed to synthetic lubricants or hot ambient air.

Where the Airtac SE50 Standard Cylinder SE50X700H Is Used
Hot-End Glass Transfer
Pushes lehr conveyor pallets in a glass annealing line where ambient heat requires the 150 C FKM seal and the 982 N force easily overcomes chain drag.
Thermoform Web Indexing
Drives a 700 mm indexing arm to pull heated plastic film into a packaging press, utilizing the adjustable cushion to soften the rapid deceleration of the long stroke.
Automotive Paint Dip Arm
Actuates a dipping fixture carrying small parts through a high-temperature curing oven, leveraging the tie-rod-free extruded profile to prevent paint pooling on the cylinder body.
Is the Airtac SE50 Standard Cylinder SE50X700H the Right Cylinder?
Selecting the SE50X700H makes sense when your mechanism requires a moderate 982 N push at 0.5 MPa across a long 700 mm span. If your payload is lighter, stepping down to the 40 mm bore drops the push force to 628 N but shrinks the physical envelope. Conversely, if you need more authority, the 63 mm bore raises the 0.5 MPa push to 1559 N. Keep in mind that a plain SE cylinder will drift if air pressure is lost or the valve is centered; it cannot hold a vertical load safely without a pilot-operated check valve or a BSE rod lock variant.
With a 700 mm stroke, the 20 mm piston rod experiences elevated bending moments under side loads, so an external guide rail is strongly recommended to prevent premature bearing wear. This model uses a PT1/4 port and M16x1.5 rod thread. It is dimensionally interchangeable with other ISO 15552 profile cylinders, allowing you to drop it into existing 50 mm mounting footprints without altering the bracketry.
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 SE50X700H FAQ
At 0.5 MPa, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force increases to 1374 N, with a maximum push capacity of 200 kgf at 1.0 MPa. The operating speed ranges from 30-800 mm/s.
Yes, it is dimensionally interchangeable with other ISO 15552 profile cylinders, matching standard 50 mm mounting dimensions and PT1/4 ports. However, it cannot hold a load if air pressure drops; the adjustable cushion only decelerates the piston near the end caps and acts as a brake. For position holding, consider a BSE rod lock variant.
