About the Airtac SC50 Standard Cylinder SC50X90H
The SC50X90H is a double-acting pneumatic cylinder with a 50 mm bore and 90 mm stroke, fitted with Viton (FKM) seals for reliable operation in high-temperature environments up to 150 °C. It generates a theoretical push force of 982 N at 0.5 MPa and can reach 1767 N at the maximum operating pressure of 0.9 MPa, making it a strong performer for its compact 150 mm body length.
This tie-rod cylinder uses a 20 mm diameter piston rod with an M16x1.5 male thread and PT1/4 ports. The 21 mm adjustable air cushion at each end decelerates the piston smoothly, reducing end-of-stroke impact. Its shorter overall length compared to ISO 15552 profiles makes it a space-efficient choice where genuine AirTAC build quality is required.

Where the Airtac SC50 Standard Cylinder SC50X90H Is Used
High-Temperature Process Automation
With Viton seals rated for 0–150 °C, this cylinder is ideal for actuating dampers, diverters, or clamps near ovens, autoclaves, and foundry equipment where standard seals would degrade.
Heated Press & Forming
Delivers 1767 N of clamping force at 0.9 MPa for hot-press fixtures, thermoforming tooling, and heated platen actuation, maintaining seal integrity in sustained high-temperature cycles.
Chemical Environment Sorting
The FKM seal material resists aggressive chemicals and solvents better than standard TPU, making it suitable for sorting gates or ejectors in chemical processing and cleaning lines.
Is the Airtac SC50 Standard Cylinder SC50X90H the Right Cylinder?
Choose the SC50X90H when your application needs a 50 mm bore force class in a heat-intensive setting. If 982 N at 0.5 MPa is insufficient, stepping up to the SC63 bore provides 1559 N; if the force is excessive and you can accept a smaller envelope, the SC40 delivers 628 N. Always match the replacement cylinder on all five key points: 50 mm bore, 90 mm stroke, PT port thread, basic (no) mounting, and the Viton seal material.
For this 90 mm stroke, the standard 20 mm rod provides good rigidity against bending. If your load applies a significant side force, consider adding an external linear guide to protect the rod bearing and seals from premature wear.
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 SC50X90H FAQ
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
No. The SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder, so dimensions and mounting are not interchangeable. It is a direct replacement only for another AirTAC SC50 tie-rod cylinder matching the 90 mm stroke, PT ports, and Viton seals.
