About the Airtac SC50 Standard Cylinder SC50X145S
The AirTAC SC50X145S is a double-acting tie-rod cylinder with a 50 mm bore and 145 mm stroke, factory-equipped with a built-in magnet (-S suffix) so CMSG/DMSG/EMSG reed or solid-state sensors clamp directly onto the barrel for contactless position sensing. At 0.5 MPa it supplies 982 N pushing force and 825 N pulling force, rising to 1767 N push at the 0.9 MPa maximum operating pressure.
This 145 mm stroke is a standard length within the 50 mm bore’s 1200 mm maximum. The 20 mm diameter piston rod carries an M16x1.5 thread, and the adjustable air cushion (21 mm length) decelerates the piston smoothly at both ends. Ports are PT1/4, and the body length A is 150 mm, giving a total extended length of approximately 295 mm.

Where the Airtac SC50 Standard Cylinder SC50X145S Is Used
Packaging Line Diverters
The 145 mm stroke and built-in magnet suit medium-reach diverter gates on packaging conveyors. CMSG sensors confirm gate position at each cycle, supporting reliable sortation at line speed.
Clamping & Fixturing
With 1767 N of clamping force available at 0.9 MPa, the SC50X145S securely holds workpieces in CNC fixtures. The magnet option provides clamp/unclamp verification to the machine controller.
Material Lift Assist
Used in light-duty vertical lifts, the 825 N pull force retracts a platen or hook over 145 mm. Sensor feedback ensures the load is fully raised before horizontal transfer begins.
Is the Airtac SC50 Standard Cylinder SC50X145S the Right Cylinder?
Choose the SC50X145S when your application needs roughly 1000 N of push force at standard shop air. If you require more force, step up to the SC63 bore (1559 N push at 0.5 MPa); if you need a lighter, more compact actuator, the SC40 bore delivers 628 N push at 0.5 MPa. The built-in magnet lets you add CMSG/DMSG/EMSG sensors without any adapter brackets, simplifying stroke-end or mid-stroke confirmation.
For a direct replacement, match five points: 50 mm bore, 145 mm stroke, PT1/4 ports, the -S magnet option, and the basic (no accessory) mounting configuration. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders; it must replace another AirTAC SC50 of the same configuration.
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 SC50X145S FAQ
At 0.5 MPa the cylinder produces 982 N pushing and 825 N pulling. At 0.7 MPa push force is 1374 N, and at the maximum operating pressure of 0.9 MPa it reaches 1767 N push. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes. The -S suffix means a magnet is built into the piston, so CMSG (reed) or DMSG/EMSG (solid-state) sensors clamp onto the barrel’s sensor groove without any additional brackets or modifications.
