About the Airtac SE50 Standard Cylinder SE50BX250
The AirTAC SE50BX250 is a double-acting, single-rod ISO 15552 profile cylinder engineered for demanding environments. It delivers a robust 982 N push force at 0.5 MPa, utilizing a 20 mm rod with an M16x1.5 thread. Because this specific SKU features a SUS304 stainless steel rod (code B), it is purpose-built for corrosive or washdown applications where a standard hard-chrome carbon rod would degrade.
The extruded aluminum barrel design omits external tie rods, yielding a smooth, flush body that resists debris buildup and simplifies mounting. Field-adjustable pneumatic cushioning at both stroke ends allows technicians to fine-tune end-of-stroke deceleration, softening hard impacts during high-speed 30-800 mm/s operation. Note that this specific configuration does not include a built-in magnet, meaning it is not natively compatible with CMSE or DMSE position sensors without modification.

Where the Airtac SE50 Standard Cylinder SE50BX250 Is Used
Stainless Pouch Sealing
Drives a 250 mm sealing jaw stroke in food-grade packaging lines, using the 982 N push force and SUS304 rod to withstand daily washdowns without corroding.
Bottle Diverter Gate
Actuates routing arms on beverage conveyors where the smooth, tie-rod-free extruded profile prevents water and product debris from accumulating on the cylinder body.
Lab Sample Handler
Positions fluidic cassettes in clinical analyzers, benefiting from the non-magnetic, clean stainless steel rod and adjustable end cushions to protect delicate glass vials during transit.
Is the Airtac SE50 Standard Cylinder SE50BX250 the Right Cylinder?
Delivering 982 N of push at 0.5 MPa, this 50 mm bore sits perfectly between the 40 mm (628 N) and 63 mm (1559 N) models. If your application requires less force and faster cycling, step down to the 40 mm bore; if you are moving heavier jigs or pressing operations, step up to the 63 mm bore. When retrofitting an existing fixture, this cylinder serves as a direct ISO 15552 replacement, matching standardized mounting and PT1/4 port dimensions without requiring custom brackets.
With a 250 mm stroke, the 20 mm stainless rod carries a respectable side-load capacity, but long unsupported strokes still induce rod-bearing bending. For high radial loads, pair this cylinder with an external guide rail to prevent premature seal wear. Remember that a standard SE cylinder does not hold its position when air is exhausted or a valve centers; if your process requires fail-safe load holding, integrate an external pilot-operated check valve or 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 SE50BX250 FAQ
