About the Airtac SC50 Standard Cylinder SC50X100SN
The SC50X100SN is a double-acting AirTAC SC tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa). Its 50 mm bore and 100 mm stroke make it a compact workhorse for medium-duty clamping, pressing, and ejecting tasks. The built-in magnet allows CMSG/DMSG/EMSG sensors to clamp directly onto the barrel for reliable end-of-stroke detection.
This model uses NBR (nitrile) seals, suitable for standard industrial environments within a -20 to +70 °C temperature range. The 20 mm diameter piston rod and PT1/4 port thread provide robust mechanical connection and airflow. With a body length A of 150 mm, the total extended length is approximately 250 mm, fitting neatly into space-constrained machine frames.

Where the Airtac SC50 Standard Cylinder SC50X100SN Is Used
Automated Fixture Clamping
Applies 1767 N of clamping force at 0.9 MPa to hold workpieces securely on CNC machining centres and welding jigs, with magnetic sensors confirming clamp/unclamp status.
Part Rejection & Sorting
Drives a high-speed pusher arm on a conveyor line to divert defective products. The 100 mm stroke provides a clean, repeatable push-off action at cycle rates up to 800 mm/s.
Assembly Press Operations
Delivers controlled insertion force for press-fitting bearings, bushings, or dowel pins into housings. The adjustable air cushion decelerates the rod smoothly at the end of the press stroke.
Is the Airtac SC50 Standard Cylinder SC50X100SN the Right Cylinder?
For applications needing more force, consider stepping up to the SC63 bore (1559 N push at 0.5 MPa). If space is the primary constraint, the SC40 bore (628 N push at 0.5 MPa) offers a smaller footprint. This cylinder includes a magnet (-S suffix) for sensor mounting and NBR seals (-N suffix). When replacing, match five key points: 50 mm bore, 100 mm stroke, PT1/4 port thread, the built-in magnet for sensors, and the basic (no bracket) mounting configuration. For strokes of 300 mm or longer, evaluate side-load conditions and consider an external guide or guided cylinder to protect the rod bearing from bending moments.

- ✓ 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 SC50X100SN FAQ
At 0.5 MPa, the cylinder provides 982 N extending (push) and 825 N retracting (pull). At 0.7 MPa, push force is 1374 N. The maximum operating force at 0.9 MPa is 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes. The -S suffix in the model code means a magnet is built into the piston. This allows you to mount AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder barrel's sensor groove for contactless position sensing.
