About the Airtac SC50 Standard Cylinder SC50X105
The AirTAC SC50X105 is a double-acting single-rod pneumatic cylinder delivering a push force of 982 N at 0.5 MPa (up to 1767 N at 0.9 MPa). With a 50 mm bore and 105 mm stroke, it fits applications needing a compact yet powerful linear push within a moderate envelope.
This model features a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 ports. The total extended body length is approximately 255 mm (150 mm body length A + 105 mm stroke), and the 21 mm adjustable air cushion at each end helps decelerate the piston quietly.

Where the Airtac SC50 Standard Cylinder SC50X105 Is Used
Material Stop/Gate
Actuates a pop-up stop on a low-speed conveyor line, reliably halting totes or cartons with 982 N of push force at standard shop air.
Clamping Fixture
Provides consistent clamping pressure for a CNC drilling jig, holding workpieces securely during machining cycles without over-deflection.
Packaging Plunger
Drives a short-stroke plunger to insert dividers into a case packer, leveraging the 105 mm stroke for a precise, repeatable insertion depth.
Is the Airtac SC50 Standard Cylinder SC50X105 the Right Cylinder?
The SC50X105 suits mid-force clamping, pressing, and transfer tasks. If your load requires more force, step up to the 63 mm bore (1559 N at 0.5 MPa); for lighter, faster cycling, the 40 mm bore (628 N at 0.5 MPa) may suffice. For strokes over 300 mm, consider an external guide to protect the rod from side loads.
When replacing an existing cylinder, match five points: 50 mm bore, 105 mm stroke, PT1/4 port thread, basic (no bracket) mounting, and no magnet. This ensures a direct dimensional and performance swap with another AirTAC SC50 tie-rod unit.
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 SC50X105 FAQ
At 0.5 MPa, push force is 982 N and pull force is 825 N. At the maximum operating pressure of 0.9 MPa, push force reaches 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
No. The SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 cylinder, so it is not dimensionally interchangeable. Only replace with another AirTAC SC50 tie-rod cylinder matching the same bore, stroke, port thread, and mounting.
