About the Airtac SC100 Standard Cylinder SC100X1275S
The AirTAC SC100X1275S is a double-acting single-rod tie-rod cylinder delivering 3927 N of push force at 0.5 MPa (up to 7068 N at 0.9 MPa). Its 1275 mm stroke stays within the 1500 mm maximum standard stroke for the 100 mm bore, making this a standard-stroke model ready for long linear movements.
A 25 mm diameter piston rod and 29 mm adjustable air cushion at each end provide smooth deceleration even under high inertial loads. The built-in magnet (suffix -S) allows CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for reliable end-of-stroke or mid-position sensing without external brackets.

Where the Airtac SC100 Standard Cylinder SC100X1275S Is Used
Long-Reach Part Transfer
Moves heavy components or pallets across wide conveyor gaps with 1275 mm of stroke, using the built-in magnet for end-position confirmation.
Press-Feed Automation
Pushes sheet metal or composite blanks into stamping presses, where the 29 mm cushion absorbs impact and the sensor magnet confirms each cycle.
Palletising Pusher
Drives a pusher plate to align heavy pallets or cases, with 7068 N of force at 0.9 MPa handling stubborn loads.
Is the Airtac SC100 Standard Cylinder SC100X1275S the Right Cylinder?
This 100 mm bore cylinder suits applications needing roughly 4000 N at standard plant pressure. If your force requirement is lower, stepping down to an 80 mm bore (2513 N at 0.5 MPa) saves space and air consumption. For higher force, the 125 mm bore provides 6136 N at 0.5 MPa.
At 1275 mm stroke, the rod is long and unsupported side loads can cause bending or bearing wear. Use an external linear guide or a guided-cylinder assembly to absorb side forces. For replacement, match five points: 100 mm bore, 1275 mm stroke, PT port thread, the built-in magnet (-S), and your required mounting accessory (this model is basic, order F-SC100LB/FA/FB/CA/CB/TC separately if needed).
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 SC100 Standard Cylinder SC100X1275S FAQ
At 0.7 MPa the cylinder produces 5497 N of push force. At the maximum operating pressure of 0.9 MPa it reaches 7068 N. Pull force at 0.5 MPa is 3681 N.
Yes. The -S suffix means a magnet is built into the piston, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors clamp directly onto the barrel. The cylinder does not include the sensors or mounting accessories; order those separately.
