About the Airtac SC40 Standard Cylinder SC40X170H
The SC40X170H is a double-acting single-rod pneumatic cylinder with a 40 mm bore and 170 mm stroke, built on the compact AirTAC SC tie-rod platform. It delivers 628 N of push force at 0.5 MPa (879 N at 0.7 MPa), driven by a 16 mm diameter piston rod with M12x1.25 male threads.
This model carries the 'H' suffix, specifying Viton (FKM) piston and rod seals. The high-temperature seal package shifts the operating range from the standard -20–+70 °C up to 0–+150 °C, making the cylinder suitable for autoclaves, foundry equipment, and other hot-zone applications. Ports are PT1/4, and the adjustable air cushion is 21 mm long.

Where the Airtac SC40 Standard Cylinder SC40X170H Is Used
Hot-Zone Gate Actuation
Viton seals permit operation up to 150 °C, so the SC40X170H can directly control a diverter gate or damper on a heated process duct where standard seals would degrade.
Autoclave / Steriliser Door
The 170 mm stroke opens a small steriliser lid or autoclave door. Viton seals withstand repeated steam cycles and high-temperature exposure without hardening.
Soldering & Curing Fixtures
Ideal for a clamping or eject station close to a heat source. The 16 mm rod and 628 N push force hold parts during soldering, curing, or hot-plate welding.
Is the Airtac SC40 Standard Cylinder SC40X170H the Right Cylinder?
Choose the SC40 bore when your application needs 528–628 N of force at standard plant pressure (0.5 MPa). If you need roughly 50 % more force, step up to the SC50 bore (825 N pull / 982 N push at 0.5 MPa). For a 170 mm stroke, the SC40 body length A is 142 mm, giving an extended length of approximately 312 mm.
For replacement, match five points: 40 mm bore, 170 mm stroke, PT1/4 ports, basic (no bracket) mounting, and no magnet. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders. If the rod sees side load, add an external guide or switch to a guided cylinder.
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 SC40 Standard Cylinder SC40X170H FAQ
At 0.7 MPa supply pressure the SC40X170H generates 879 N pushing force and 739 N pulling force (theoretical). At the maximum operating pressure of 0.9 MPa, push force reaches 1130 N.
No. The AirTAC SC series is a tie-rod cylinder that is shorter in overall length than an ISO 15552 profile cylinder. It will only drop into a mounting designed for an AirTAC SC (or equivalent tie-rod) cylinder of the same bore, stroke, port thread, and mounting style.
