About the Airtac SC50 Standard Cylinder SC50X225SH
The AirTAC SC50X225SH is a double-acting single-rod cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. Its 225 mm stroke is well within the 1200 mm maximum standard stroke for the 50 mm bore, making it a balanced choice for medium-reach linear actuation. The 20 mm diameter piston rod and 21 mm adjustable air cushion at each end provide smooth deceleration, while the PT1/4 port supplies ample flow for speeds up to 800 mm/s.
This model is factory-equipped with a built-in magnet (-S suffix) and Viton (FKM) seals (-H suffix). The magnet allows direct mounting of CMSG, DMSG, or EMSG sensors on the tie-rod barrel for non-contact position sensing. The high-temperature seal package shifts the operating range to 0 to +150 °C, making this cylinder suitable for autoclaves, drying lines, and hot-process automation where standard TPU seals would degrade.

Where the Airtac SC50 Standard Cylinder SC50X225SH Is Used
Hot-Process Automation
With Viton seals rated for 0-150°C, this cylinder excels in autoclave door actuation, steam-line valve control, and drying oven conveyors where heat would destroy standard seals.
Sensor-Monitored Pressing
The built-in magnet and 1767 N max force suit heat-assisted pressing, clamping, or forming stations. CMSG/DMSG sensors provide end-of-stroke confirmation to the PLC for quality interlocking.
High-Temperature Sorting Gates
Use the 225 mm stroke to divert hot products on a conveyor. The adjustable cushion protects the mechanism from shock, while the Viton seals ensure long life despite radiant heat.
Is the Airtac SC50 Standard Cylinder SC50X225SH the Right Cylinder?
Select the SC50 bore when your application needs around 1000 N of force at standard plant air pressure; stepping down to a 40 mm bore provides 628 N, while moving up to a 63 mm bore delivers 1559 N at the same 0.5 MPa. The 225 mm stroke is a standard length, but always check for side loading—if the rod experiences lateral force, pair this cylinder with an external guide or switch to a guided actuator to prevent rod bearing wear and seal failure.
For a correct drop-in replacement, match five points: the 50 mm bore, 225 mm stroke, PT port thread, the built-in magnet for sensor compatibility, and the Viton seal material for high-temperature resistance. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC series cylinders with identical specifications.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for 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 (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SC50 Standard Cylinder SC50X225SH FAQ
The 50 mm bore generates 982 N pushing and 825 N pulling at 0.5 MPa. At 0.7 MPa, push force is 1374 N, and at the maximum operating pressure of 0.9 MPa, it reaches 1767 N. These values are theoretical; account for a 10-15% safety margin for dynamic loads.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 cylinder (body length A is 150 mm for the 50 mm bore). It is not dimensionally interchangeable with ISO 15552 profiles. It will only drop into mounts designed for an AirTAC SC50 tie-rod cylinder with matching stroke, magnet, and seal options.
