About the Airtac SC80 Standard Cylinder SC80X45S
The AirTAC SC80X45S is an 80 mm bore, 45 mm stroke double-acting tie-rod cylinder featuring a built-in magnet. With the -S suffix, a magnetic band is integrated into the piston, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the barrel for precise, non-contact end-of-stroke or mid-stroke position sensing.
At the standard 0.5 MPa operating pressure, this cylinder generates a push force of 2513 N and a pull force of 2268 N, rising to 4523 N push at 0.9 MPa. The 25 mm diameter rod and PT3/8 ports suit medium-duty clamping and pressing tasks. The 45 mm stroke fits into compact fixtures where a short, powerful linear motion is needed.

Where the Airtac SC80 Standard Cylinder SC80X45S Is Used
Sensor-Controlled Clamping
The built-in magnet allows direct mounting of CMSG/DMSG sensors to verify clamp position in automated welding or assembly fixtures, ensuring the 45 mm stroke is fully extended before the cycle continues.
Short-Stroke Part Stops
Delivers 2513 N at 0.5 MPa to halt pallets or totes on a conveyor line. The 45 mm stroke provides a crisp, defined stop position with sensor feedback confirming the stop is engaged.
Press-Fit Insertion
Ideal for pressing bushings or pins into housings with a controlled 45 mm insertion depth. The 4523 N force at 0.9 MPa handles tight interference fits, while the sensor confirms the ram has retracted.
Is the Airtac SC80 Standard Cylinder SC80X45S the Right Cylinder?
Select the SC80 bore when your application needs roughly 2500 N of push force at 0.5 MPa. If your load is below 1500 N, stepping down to the SC63 (1559 N push at 0.5 MPa) can reduce air consumption and footprint. For higher forces, the SC100 provides 3927 N push at the same pressure.
When replacing an existing cylinder, match five key points: 80 mm bore, 45 mm stroke, PT3/8 port thread, the built-in magnet (-S) for sensor compatibility, and the basic mounting style. This SC model 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 SC80 Standard Cylinder SC80X45S FAQ
At 0.7 MPa (7 bar), the SC80 bore generates a theoretical push force of 3518 N. The pull force on the rod side at the same pressure is 3175 N, accounting for the 25 mm rod diameter.
Yes. The -S suffix indicates a built-in magnetic ring on the piston. This makes it fully compatible with AirTAC CMSG (reed) and DMSG/EMSG (solid-state) sensors, which simply clamp onto the tie-rod barrel without additional brackets.
