Airtac SE50 Standard Cylinder SE50X70
The AirTAC Airtac SE50 Standard Cylinder SE50X70 is a genuine double-acting ISO 15552 / VDMA 24562 profile-barrel air cylinder with a Ø50mm bore and 70mm stroke, PT1/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SE50 Standard Cylinder SE50X70
The AirTAC SE50X70 is a double-acting single-rod ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa and 1374 N at 0.7 MPa. Its square extruded aluminum barrel eliminates external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames while retaining the standardized ISO 15552 interface for universal hardware compatibility.
Field-adjustable pneumatic cushioning at both ends allows you to tune end-of-stroke deceleration via a set screw, softening hard impacts during high-speed 30-800 mm/s cycling. This specific SKU lacks a built-in magnet, so it is ready for basic actuation but will not host CMSE or DMSE position sensors without modification.

Where the Airtac SE50 Standard Cylinder SE50X70 Is Used
Carton Erector Flaps
Provides the 982 N push at 0.5 MPa required to snap heavy corrugated cardboard flaps into position during automated case erecting, utilizing the 70 mm stroke for rapid, short-travel actuation.
Diverter Gate Arm
Powers a pneumatic diverter gate on a packaging conveyor, using the adjustable end cushions to softly arrest the 70 mm stroke and prevent harsh mechanical slamming at high cycle rates.
Press Fit Subassembly
Drives a small bearing or pin into a housing on an assembly line, where the tie-rod-free extruded profile allows the cylinder to sit flush against the machine's sub-plate without protruding hardware.
Is the Airtac SE50 Standard Cylinder SE50X70 the Right Cylinder?
At 0.5 MPa, this 50 mm bore yields 982 N of push force. If your application requires less force, stepping down to the 40 mm bore provides 628 N. If you need substantially more thrust, stepping up to the 63 mm bore provides 1559 N. Because this is a plain double-acting cylinder, it cannot hold a load if air pressure drops or the valve centers; the piston will drift. For position holding, consider the BSE rod lock variant.
With a 70 mm stroke, side-load stress on the rod bearing is minimal. However, for any future upgrades exceeding 300 mm of travel, adding an external guide is recommended to prevent rod-bearing bending. This model features a PT1/4 port, a Ø20 mm rod with an M16x1.5 thread, and uses the standard ISO 15552 mounting accessories.
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 SE50X70 FAQ
The SE50X70 generates 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a maximum of 200 kgf at 1.0 MPa. It features a PT1/4 port and a Ø20 mm hard-chrome plated rod with an M16x1.5 thread.
It is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other standard profile cylinders using identical mounting hardware. However, it is a standard double-acting cylinder, so it does not hold position or lock loads when air is exhausted; for that, you would need a BSE series rod lock.
