About the Airtac SC50 Standard Cylinder SC50X1000SH
The SC50X1000SH is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at 0.9 MPa, making it a capable mid-bore actuator for long linear moves. Its 20 mm diameter piston rod and 21 mm adjustable air cushion at each end provide smooth deceleration across the full 1000 mm stroke, while the tie-rod construction keeps the assembly serviceable.
This model is factory-equipped with a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors, eliminating the need for external switch rails. The -H suffix specifies Viton (FKM) seals, shifting the operating temperature range to 0–150 °C and suiting applications with elevated ambient heat or aggressive media.

Where the Airtac SC50 Standard Cylinder SC50X1000SH Is Used
Hot-Zone Material Handling
The Viton seals withstand ambient temperatures up to 150 °C, allowing the SC50X1000SH to operate pushers, ejectors, or transfer arms inside ovens, autoclaves, or near heated platens where standard seals would degrade.
Long-Stroke Sorting Gate
With 1000 mm of travel and a built-in magnet for end-of-stroke sensing, this cylinder reliably actuates diverter gates on high-speed conveyor lines, routing packages or parcels between multiple lanes.
Sterilizer Door Actuation
The FKM seal material resists steam and chemical cleaning agents, making this cylinder suitable for opening and closing access doors on medical or laboratory sterilizers that cycle through high-temperature washdowns.
Is the Airtac SC50 Standard Cylinder SC50X1000SH the Right Cylinder?
For applications needing more force, stepping up to the 63 mm bore SC63 series provides 1559 N at 0.5 MPa. If space or weight is a constraint, the 40 mm bore SC40 delivers 628 N at the same pressure. At 1000 mm stroke, the unsupported rod length demands careful alignment; any side load will cause rod bending and premature bearing wear. For guided linear motion, pair this cylinder with an external guide rail or consider a guided-cylinder assembly.
To ensure a drop-in replacement, match five key points: 50 mm bore, 1000 mm stroke, PT port thread, the built-in magnet (-S), and the basic (no bracket) mounting configuration. This SC cylinder is a tie-rod design 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 SC50X1000SH FAQ
At 0.5 MPa the cylinder pushes with 982 N and pulls with 825 N. At 0.7 MPa push force is 1374 N, and at the maximum operating pressure of 0.9 MPa it reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No. The SC50X1000SH is a double-acting cylinder that requires continuous air pressure to maintain position. If pressure is lost or the directional valve is centered, the piston will drift or drop. For load holding, an external rod lock, pilot-operated check valve, or mechanical brake must be added.
