About the Airtac SC50 Standard Cylinder SC50X1050SH
The AirTAC SC50X1050SH is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore and a long 1050 mm stroke, this model is built for applications needing extended linear travel, such as material transfer or long-reach actuation. The 20 mm diameter piston rod and 21 mm adjustable air cushion at each end ensure smooth deceleration, while the body length A is 150 mm.
This variant includes a built-in magnet (-S suffix) for direct mounting of CMSG, DMSG, or EMSG sensors, enabling precise end-of-stroke or mid-stroke position feedback without external brackets. The -H suffix specifies Viton (FKM) seals, shifting the operating temperature range from the standard -20 to +70°C up to 0 to +150°C, making it suitable for high-temperature environments like foundries or drying equipment. It uses standard PT ports and is a genuine AirTAC tie-rod cylinder.

Where the Airtac SC50 Standard Cylinder SC50X1050SH Is Used
High-Temperature Material Transfer
The 1050 mm stroke and Viton seals (0 to +150°C) make this cylinder ideal for pushing trolleys or transferring parts through industrial ovens, drying tunnels, or paint curing lines where standard seals would fail.
Long-Reach Part Rejection
Use the built-in magnet and sensors for precise position confirmation on a long-stroke reject station, pushing defective products off a high-speed conveyor with 1767 N of force at full pressure.
Foundry Mold Actuation
Deploy this cylinder in foundry automation to move core-setting mechanisms. The FKM seals withstand ambient heat, and the adjustable air cushion protects the mold from impact damage at the end of the long stroke.
Is the Airtac SC50 Standard Cylinder SC50X1050SH the Right Cylinder?
For a 50 mm bore, this cylinder provides 982 N of push force at 0.5 MPa. If your load requires more force, stepping up to a 63 mm bore (SC63 series) provides 1559 N at the same pressure. For a lighter, more compact solution, a 40 mm bore offers 628 N. This model's 1050 mm stroke is within the 1200 mm maximum standard stroke for bore 50, so it is a standard catalog item.
For any stroke over 300 mm, especially with a 20 mm rod, carefully evaluate side loads. A long, unsupported rod is susceptible to bending under lateral force. To prevent premature seal and bearing wear, use an external guide system or a guided cylinder. When replacing this unit, match five key points: 50 mm bore, 1050 mm stroke, PT port thread, the built-in magnet (-S), and the Viton seal material (-H).
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 SC50X1050SH FAQ
At the standard 0.5 MPa operating pressure, 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 increases to 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
Yes. The -S suffix indicates a built-in magnet around the piston. This allows you to mount AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder barrel's sensor groove to detect piston position without any additional mounting hardware.
