About the Airtac SE50 Standard Cylinder SE50BX300SH
The AirTAC SE50BX300SH is a double-acting single-rod ISO 15552 profile cylinder engineered for demanding environments. It features a 50 mm bore and a 300 mm stroke, generating 982 N of push force and 825 N of pull force at 0.5 MPa. Built with a SUS304 stainless steel rod and FKM Viton seals, this variant reliably operates in temperatures up to 150 C, making it highly suited for corrosive washdown or high-heat industrial duties.
Unlike traditional tie-rod designs, the square extruded aluminum barrel lacks external tie rods, yielding a compact, flush-mounting profile that resists corrosion and simplifies sensor placement. The integrated magnet (-S) directly supports AirTAC CMSE reed and DMSE electronic position sensing. Furthermore, the field-adjustable air cushioning at both ends allows technicians to precisely tune end-of-stroke deceleration via a set screw, effectively softening hard impacts at operating speeds up to 800 mm/s.

Where the Airtac SE50 Standard Cylinder SE50BX300SH Is Used
Thermoform Packaging Press
Drives the forming die on a food-grade thermoform packaging line, utilizing the 982 N push force and SUS304 rod to withstand high-temperature steam washdowns.
Lab Drying Oven Door
Actuates the heavy insulated door of an industrial 150 C laboratory drying oven, relying on the FKM Viton seals to prevent rubber degradation.
Plastic Injection Unloading
Ejects hot plastic parts from an injection molding machine, where the 300 mm stroke and adjustable pneumatic cushioning safely decelerate fast-moving payloads.
Is the Airtac SE50 Standard Cylinder SE50BX300SH the Right Cylinder?
If sizing this 50 mm bore, consider stepping down to a 40 mm cylinder (628 N push @0.5 MPa) for lighter loads, or up to a 63 mm bore (1559 N push @0.5 MPa) when higher thrust is required. Because this is a 300 mm stroke, the extended 20 mm rod and M16x1.5 thread face increased bending moments under side loads; an external guide rail is strongly recommended to prevent premature rod-bearing wear. Remember that the adjustable air cushion only decelerates the piston near stroke end—it does not hold the load. If the application must maintain position without live air pressure, a BSE rod lock or external pilot-operated check valve is necessary. For direct retrofits, this cylinder is dimensionally interchangeable per ISO 15552 standards, matching the PT1/4 port and standard mounting accessories.
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 SE50BX300SH FAQ
At 0.5 MPa, the SE50BX300SH provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force increases to 1374 N, with a maximum push capacity of 200 kgf at 1.0 MPa. It operates on filtered air at 30-800 mm/s.
Yes, it is dimensionally interchangeable per ISO 15552, serving as a direct replacement for other ISO 15552 profile cylinders. However, it does not hold position when air is lost; for load holding, use an AirTAC BSE rod lock variant.
