About the Airtac SE50 Standard Cylinder SE50AX135
The AirTAC SE50AX135 is a double-acting, single-rod ISO 15552 profile cylinder delivering 982 N of push force and 825 N of pull force at 0.5 MPa. Engineered with a square extruded aluminum barrel that eliminates external tie rods, this unit provides a flush, corrosion-resistant body that simplifies mounting and equipment cleanup. The stroke is set at 135 mm, and the bore utilizes a PT1/4 port paired with a 20 mm rod.
This specific configuration features a SUS420J2 stainless steel rod (material code A) for superior resistance to moisture and washdown chemicals. Because this SKU omits the -S magnet, it does not natively support CMSE or DMSE position sensing without modification. Field-adjustable pneumatic cushioning at both end caps 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 SE50AX135 Is Used
Flow Wrapper Film Cut-off
Drives the sealing and cutting jaw assembly on a horizontal flow wrapper, utilizing the 982 N push force to cleanly sever packaging film at 135 mm stroke.
Lab Sample Centrifuge Loader
Indexes sample racks into a laboratory centrifuge chamber, where the SUS420J2 stainless rod withstands daily chemical washdowns and moisture exposure.
Bottling Line Diverter Gate
Actuates a pneumatic sorting flap on a beverage bottling line, using the adjustable end cushions to soften stroke ends at high cycling speeds.
Is the Airtac SE50 Standard Cylinder SE50AX135 the Right Cylinder?
This 50 mm bore provides 982 N push at 0.5 MPa. If your assembly requires less force, the 40 mm neighbor offers 628 N; if you need more power, the 63 mm bore provides 1559 N. As a standard double-acting cylinder, it relies on continuous air pressure to hold a load—if air is lost or the valve centers, the piston will drift. For critical load-holding, consider the BSE rod-lock variant. At 135 mm stroke, the 20 mm rod and M16x1.5 thread handle moderate side loads, but long unsupported strokes should always use an external guide to prevent rod-bearing bending. Its ISO 15552 footprint ensures drop-in dimensional interchangeability with other ISO 15552 profile cylinders, sharing standard mounting hardware.
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 SE50AX135 FAQ
The SE50AX135 delivers a push force of 982 N and a pull force of 825 N at 0.5 MPa. At 0.7 MPa, the push force is 1374 N, with a maximum push capacity of 200 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
Yes, the SE50AX135 is dimensionally interchangeable per ISO 15552 standards, allowing it to serve as a drop-in replacement for other ISO 15552 profile cylinders using the same mounting hardware. Note that this specific SKU lacks a built-in magnet, so it will not trigger CMSE or DMSE sensors without modification.
