About the Airtac SE50 Standard Cylinder SE50BX800S
The AirTAC SE50BX800S is a double-acting, single-rod ISO 15552 profile cylinder engineered for long-stroke actuation. It delivers a robust 982 N push force at 0.5 MPa, utilizing a 50 mm bore and an 800 mm stroke. This specific configuration pairs a SUS304 stainless steel rod (code B) with a built-in magnet (code S), making it highly suited for washdown environments and position-sensing requirements.
Unlike traditional tie-rod designs, its extruded aluminum square barrel omits external tie rods, yielding a compact, corrosion-resistant profile that mounts flush. 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 during high-speed cycling.

Where the Airtac SE50 Standard Cylinder SE50BX800S Is Used
Bottling Line Diverter
Sorts heavy PET bottle containers on a washdown packaging line, leveraging the 982 N push force and SUS304 stainless rod to withstand frequent moisture exposure.
Palletizing Push Arm
Actuates a 800 mm reach pusher to index filled cardboard cartons onto wooden pallets, relying on the adjustable cushion to soften end-of-stroke strikes at high speed.
Pharma Washdown Gate
Drives a 50mm bore stainless-rod mechanism to open sterilization chamber doors, using the -S magnet with DMSE electronic sensors to verify full extension.
Is the Airtac SE50 Standard Cylinder SE50BX800S the Right Cylinder?
When sizing this actuator, compare its 982 N push at 0.5 MPa against adjacent bores to ensure optimal fit. Stepping down to a 40 mm bore yields 628 N, while stepping up to a 63 mm bore provides 1559 N, giving you a clear scaling path for load adjustments. Because this is an 800 mm stroke, the unsupported rod length increases the risk of rod-bearing bending under lateral stress; an external guide is strongly recommended to prevent premature seal wear.
For direct retrofits, this model conforms to ISO 15552 mounting-interface dimensions, allowing it to share standard mounting hardware with other ISO 15552 profile cylinders. It uses a PT1/4 port and a Ø20 mm rod. Note that a plain SE cylinder does not hold its load when air is lost or the valve is centered—the piston will drift. For position-holding needs, consider the BSE rod-lock variant or an external pilot-operated check valve.
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 SE50BX800S FAQ
At 0.5 MPa, this 50 mm bore cylinder provides 982 N push and 825 N pull force. 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.
No. The adjustable air cushion at both ends only decelerates the piston near the stroke end; it is not a braking mechanism. If air is lost or the valve is centered, the piston will drift. For true load holding without live pressure, use an AirTAC BSE rod-lock cylinder or an external pilot-operated check valve.
