About the Airtac SE50 Standard Cylinder SE50BX250H
The AirTAC SE50BX250H is a double-acting, single-rod ISO 15552 profile cylinder engineered for harsh environments. It delivers a robust 982 N push force at 0.5 MPa (1374 N at 0.7 MPa) across a 250 mm stroke. This specific SKU pairs a SUS304 stainless steel piston rod with a high-temperature Viton (FKM) seal, expanding the operating temperature range from -20 C up to 150 C for demanding thermal or washdown conditions.
Unlike traditional tie-rod designs, its square extruded aluminum barrel omits external tie rods, offering a compact, flush-mounting footprint that resists corrosion and simplifies sensor placement. The cylinder features field-adjustable pneumatic cushioning at both ends, allowing technicians to tune end-of-stroke deceleration via a set screw to soften hard impacts at high cycle rates.

Where the Airtac SE50 Standard Cylinder SE50BX250H Is Used
Medical Autoclave Doors
The Viton (FKM) seal and SUS304 rod withstand 150 C steam and high-pressure washdowns, providing 982 N of thrust to pivot heavy sterilization chamber doors.
Hot-Melt Adhesive Presses
Handles 250 mm stroke to actuate sealing bars in high-temperature packaging lines, where the adjustable end cushions protect the 1374 N thrust impact at 0.7 MPa.
Food Processing Diverters
The stainless SUS304 rod resists caustic CIP washdown chemicals, actuating sorting gates with a compact, tie-rod-free extruded profile that fits tight machine frames.
Is the Airtac SE50 Standard Cylinder SE50BX250H the Right Cylinder?
This 50 mm bore generates 982 N of push force at 0.5 MPa. If your application requires less force and a smaller footprint, step down to the 40 mm bore (628 N push). If your load demands more thrust, step up to the 63 mm bore (1559 N push). Because this unit lacks a built-in position magnet (no -S suffix), it cannot host AirTAC CMSE or DMSE sensors; if you need position feedback, specify the -S option.
With a 250 mm stroke, the 20 mm rod and M16x1.5 thread handle moderate side loads, but long unsupported strokes can induce rod-bearing bending. For heavy off-center loads, incorporate an external guide rail to prevent premature seal wear. Note that the adjustable air cushion only decelerates the piston near the stroke end; it does not hold the load if air pressure drops. For true position holding, explore the 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 SE50BX250H FAQ
At 0.5 MPa, the 50 mm bore provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force is 1374 N. The maximum push force is 200 kgf at 1.0 MPa. The operating speed ranges from 30-800 mm/s.
Yes. The SE50BX250H shares standardized ISO 15552 / VDMA 24562 mounting dimensions, making it a direct retrofit for other ISO 15552 profile cylinders. It uses a PT1/4 port and M16x1.5 rod thread, but note this specific unit has no sensor magnet and uses a high-temp Viton seal.
