About the Airtac SC50 Standard Cylinder SC50X260H
The SC50X260H is a double-acting tie-rod cylinder built with high-temperature Viton (FKM) seals, extending its operating range to 0–150 °C for hot environments where standard seals would degrade. With a 50 mm bore and 260 mm stroke, it produces 982 N of push force at 0.5 MPa and up to 1767 N at 0.9 MPa, driven by a 20 mm diameter piston rod with M16x1.5 male threads.
This model features PT1/4 pneumatic ports and a 21 mm adjustable air cushion at each end to decelerate the piston quietly. The body length A is 150 mm, giving a total extended length of approximately 410 mm. It is a genuine AirTAC SC-series cylinder, shorter than an ISO 15552 profile and intended as a direct replacement for same-series SC50 units with Viton seals.

Where the Airtac SC50 Standard Cylinder SC50X260H Is Used
Foundry & Heat-Treat Clamping
Viton seals allow the SC50X260H to operate reliably near furnaces and in heat-treat fixtures up to 150 °C, applying 1767 N of clamping force at 0.9 MPa.
Autoclave & Sterilisation Actuation
Withstands repeated steam sterilisation cycles. The 260 mm stroke opens and closes autoclave doors or moves trays in high-temperature medical and food-processing equipment.
Hot-Melt Dispensing & Moulding
Delivers consistent 982 N push at 0.5 MPa for adhesive dispensing heads and injection mould gate actuators, where radiant heat would harden standard polyurethane seals.
Is the Airtac SC50 Standard Cylinder SC50X260H the Right Cylinder?
Choose the SC50X260H when a 50 mm bore provides sufficient force and the ambient temperature exceeds 70 °C—the Viton seals handle continuous operation up to 150 °C. If you need more force at the same pressure, step up to the 63 mm bore (1559 N push at 0.5 MPa); for a lighter, more compact assembly, the 40 mm bore delivers 628 N. At 260 mm stroke, rod bending under side load is generally not a concern for axial applications, but any off-axis force should be managed with an external guide.
For a drop-in replacement, match five attributes: 50 mm bore, 260 mm stroke, PT1/4 ports, basic (no bracket) mounting, and the -H Viton seal designation. The SC is a tie-rod cylinder and does not interchange with ISO 15552 profiled cylinders.
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 SC50X260H FAQ
At the standard 0.7 MPa operating pressure, it generates 1374 N pushing and 825 N pulling. The maximum push force at 0.9 MPa is 1767 N, and the theoretical 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 (body length A is 150 mm for the 50 mm bore). It only directly replaces another AirTAC SC50 tie-rod cylinder with matching stroke, PT ports, basic mount, and Viton seals.
