About the Airtac SC50 Standard Cylinder SC50X50H
The SC50X50H is a double-acting AirTAC SC tie-rod cylinder with a 50 mm bore and 50 mm stroke, fitted with high-temperature Viton (FKM) seals that shift the operating range to 0–150 °C. It produces 982 N of push force at 0.5 MPa and 1767 N at 0.9 MPa, making it a compact workhorse for hot environments.
This model uses a 20 mm diameter piston rod with an M16x1.5 male thread and PT1/4 ports. The adjustable air cushion (21 mm length) decelerates the end-of-stroke travel, and the body length A is 150 mm, giving a total extended length of approximately 200 mm.

Where the Airtac SC50 Standard Cylinder SC50X50H Is Used
High-Temperature Actuation
Viton seals allow the SC50X50H to operate reliably in ambient temperatures up to 150 °C, ideal for autoclave doors, drying ovens, and foundry equipment.
Hot Press & Molding
Delivers 1767 N of thrust at 0.9 MPa for short, powerful clamping strokes in heated platen presses or rubber molding machines.
Heat-Tolerant Sorting Gates
The compact 50 mm stroke and 982 N push force at 0.5 MPa suit high-speed diverter gates on conveyors passing through heat-shrink tunnels.
Is the Airtac SC50 Standard Cylinder SC50X50H the Right Cylinder?
Choose the SC50X50H when your application requires a 50 mm stroke and exposure to elevated temperatures up to 150 °C. If you need more force, stepping up to the 63 mm bore delivers 1559 N at 0.5 MPa; for a lighter, more compact solution, the 40 mm bore provides 628 N.
For a direct replacement, match five attributes: 50 mm bore, 50 mm stroke, PT1/4 port thread, basic (no mounting accessory), and the -H Viton seal. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile 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 SC50X50H FAQ
At 0.5 MPa (approx. 5 bar), the cylinder provides 982 N extending (push) and 825 N retracting (pull). At the maximum operating pressure of 0.9 MPa, the push force reaches 1767 N.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder of the same bore and stroke. It will only drop in to replace another AirTAC SC tie-rod cylinder with matching bore, stroke, port thread, and mounting.
