About the Airtac SE50 Standard Cylinder SE50AX475
The AirTAC SE50AX475 is a double-acting, single-rod ISO 15552 profile cylinder engineered to deliver a 982 N push force at 0.5 MPa and a maximum output of 200 kgf at 1.0 MPa. It features a 475 mm stroke and a 50 mm bore, operating via a PT1/4 port. This specific SKU utilizes a SUS420J2 stainless steel rod, making it highly suitable for corrosive or washdown environments where standard carbon steel rods would degrade.
The extruded aluminum barrel design omits external tie rods, providing a smooth, flush-mounting surface that resists debris buildup and simplifies sensor placement along three integrated grooves. Field-adjustable pneumatic cushioning at both ends allows technicians to dial in the end-of-stroke deceleration via a set screw, effectively softening hard impacts when cycling at speeds up to 800 mm/s. Note that this unit lacks a built-in magnet, so it is not ready for CMSE or DMSE position sensing without modification.

Where the Airtac SE50 Standard Cylinder SE50AX475 Is Used
Food Processing Diverter
The SUS420J2 stainless rod withstands frequent washdowns, while the 982 N push force easily routes heavy bulk ingredient hoppers on a packaging line.
Bottling Line Gate
Utilizing the 475 mm stroke to extend a flow-control gate across a 450 mm conveyor belt, slowing accumulation before the capping station.
Pallet Stop Arm
Provides a firm 825 N pull force to retract a physical stop arm, allowing loaded pallets to pass through a high-speed sortation zone.
Is the Airtac SE50 Standard Cylinder SE50AX475 the Right Cylinder?
This 50 mm bore generates 982 N push at 0.5 MPa. If your application requires less force, stepping down to the 40 mm bore yields 628 N push, while moving up to the 63 mm bore provides 1559 N push for heavier loads. Because this cylinder lacks a built-in magnet, you cannot use AirTAC CMSE or DMSE electronic switches for end-of-stroke detection; if position feedback is mandatory, select an SE50X475S variant instead. The SUS420J2 stainless rod directly addresses splash and corrosion concerns.
At a 475 mm stroke, the unsupported length of the piston rod increases its susceptibility to bending under side loads. For applications involving heavy lateral offsets or dynamic moments, incorporating an external linear guide is strongly recommended to prevent premature rod-bearing wear. Being dimensionally interchangeable per ISO 15552, this cylinder serves as a direct drop-in replacement for other ISO 15552 profile cylinders, matching standard mounting footprint and port locations exactly.
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 SE50AX475 FAQ
At 0.5 MPa, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force increases to 1374 N. The absolute maximum push force is 200 kgf when operated at the maximum rated pressure of 1.0 MPa.
No, a standard SE cylinder cannot hold a load if air pressure is lost or the valve is centered; the piston will drift. The adjustable air cushion only decelerates the piston near the stroke end and does not act as a brake. For fail-safe load holding, you would need a BSE series rod lock or an external pilot-operated check valve.
