About the Airtac SE125 Standard Cylinder SE125X170S
The AirTAC SE125X170S is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks, delivering a substantial 6136 N push force at 0.5 MPa. Its square extruded aluminum barrel omits external tie rods entirely, yielding a flush, corrosion-resistant housing that mounts cleanly against machine frames while maintaining the standardized ISO 15552 footprint.
Equipped with a built-in magnet (-S), this unit seamlessly integrates AirTAC CMSE reed and DMSE electronic sensors for precise end-of-stroke detection without requiring external brackets. The field-adjustable pneumatic cushioning at both ends allows technicians to tune the 40 mm cushion length via a set screw, softly decelerating the 32 mm rod to eliminate hard end-stop impacts at high cycling speeds.

Where the Airtac SE125 Standard Cylinder SE125X170S Is Used
Heavy Press Stamping
Drives the forming die in an automotive heavy press, utilizing the 6136 N push force at 0.5 MPa to shape thick-gauge steel components reliably.
Injection Mold Ejection
Actuates the large primary ejection plate in a plastic injection molding machine, where the 170 mm stroke safely clears the mold cavity for part removal.
Structural Beam Bending
Powers a hydraulic-assisted jig in structural steel fabrication, applying up to 1252 kgf of maximum thrust to bend heavy aluminum support beams.
Is the Airtac SE125 Standard Cylinder SE125X170S the Right Cylinder?
Selecting the SE125X170S is optimal when your application demands maximum thrust within the standard ISO 15552 range, as it is the largest standard bore offering 6136 N push at 0.5 MPa. If you need to step down to reduce physical size and air consumption, the neighboring 100 mm bore provides 3927 N push at 0.5 MPa. Because this is the largest standard bore, there is no larger neighbor to step up to within the SE series.
This cylinder features a PT1/2 port and a 170 mm stroke. For retrofitting, match the 125 mm bore, 170 mm stroke, PT1/2 port, and your required mounting accessory (such as TC centre trunnion) to ensure a drop-in ISO 15552 replacement. Remember that a plain SE cylinder will drift and cannot hold a load if air pressure is lost; for critical position-holding, consider the BSE rod lock variant. Furthermore, while the robust 32 mm rod handles high side loads, any stroke exceeding 300 mm requires an external guide to prevent rod-bearing bending.
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 SE125 Standard Cylinder SE125X170S FAQ
The SE125X170S generates a push force of 6136 N and a pull force of 5734 N at 0.5 MPa. At 0.7 MPa, the push force is 8590 N, with a maximum push capacity of 1252 kgf at 1.0 MPa. The operating speed range for this 125 mm bore cylinder is 30-500 mm/s.
Yes, the SE125X170S is dimensionally interchangeable with other ISO 15552 profile cylinders, allowing you to reuse existing mounting hardware. It features field-adjustable air cushioning at both ends that decelerates the piston near the stroke end via a needle screw; however, this cushion only softens impact and does not lock or hold the load.
