The AirTAC SE50 Standard Cylinder SE50BX850S is a genuine double-acting ISO 15552 / VDMA 24562 profile-barrel air cylinder with a Ø50mm bore and 850mm stroke, PT1/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SE50BX850S is a double-acting single-rod ISO 15552 profile cylinder engineered for a 50 mm bore and an 850 mm non-standard stroke. It delivers a robust 982 N push at 0.5 MPa, utilizing a SUS304 stainless steel rod (code B) specifically chosen for corrosive or washdown environments. The square extruded aluminum barrel omits external tie rods, yielding a compact footprint that mounts flush against machine frames while resisting contamination.
This unit features a built-in magnet (code S) for non-contact position detection using AirTAC CMSE reed or DMSE electronic sensors. To absorb kinetic energy at stroke ends, field-adjustable air cushions at both ends allow technicians to tune exhaust bleed-off, softening hard mechanical impacts at operating speeds up to 30-800 mm/s.

Leveraging the SUS304 rod for washdown durability, this 850 mm stroke cylinder pushes product lanes on a food-grade packaging line, utilizing its 982 N push force to overcome friction on stainless belts.
The long 850 mm stroke extends to push corrugated cartons onto a palletizer queue, while the built-in -S magnet triggers DMSE electronic sensors to confirm full extension in the PLC.
Acting as a corrosion-resistant gate valve in a chemical testing lab, the SUS304 rod withstands solvent splashes while the adjustable cushion prevents sudden stops from jarring sensitive fluid vials.
Choosing this 50 mm bore makes sense when a machine requires 982 N of push force at 0.5 MPa. If your application carries a lighter payload, stepping down to the 40 mm bore drops the output to 628 N, saving valuable space and air volume. Conversely, heavier loads requiring more thrust should step up to the 63 mm bore, which provides 1559 N of push at 0.5 MPa. Because this model has an 850 mm stroke, the 20 mm rod and rod-end bearing face increased bending moments under side loads; always pair it with an external guide rail to prevent premature seal wear.
As a dimensionally interchangeable ISO 15552 cylinder, the SE50BX850S serves as a direct replacement for other ISO 15552 profile cylinders, matching the exact 50 mm bore, 850 mm stroke, PT1/4 port, and standardized mounting accessory footprint. Note that while its adjustable cushions decelerate the piston near stroke end, a plain SE cylinder cannot hold a load vertically if air pressure is lost; for position holding, consider a BSE rod lock variant.
Quick checklist
The 50 mm bore generates 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a maximum of 200 kgf at 1.0 MPa. The operating speed ranges from 30-800 mm/s.
Yes, the SE50BX850S is dimensionally interchangeable per ISO 15552 / VDMA 24562 standards. You can drop it into existing mounting hardware matching the 50 mm bore and 850 mm stroke without modifying the machine frame.
