About the Airtac SC50 Standard Cylinder SC50X95
The AirTAC SC50X95 is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa). Its 95 mm stroke suits medium-reach clamping, pressing, and positioning tasks where a compact footprint is needed without sacrificing thrust.
Built with a 20 mm diameter piston rod and M16x1.5 rod thread, this cylinder includes an adjustable air cushion (21 mm cushion length) to decelerate the piston smoothly. The body length A is 150 mm, giving an extended length of 245 mm. Standard PT1/4 ports and TPU seals (-20 to +70 °C) complete the package.

Where the Airtac SC50 Standard Cylinder SC50X95 Is Used
Medium-Force Part Stops
The 982 N push force at 0.5 MPa makes the SC50X95 ideal for stopping and positioning medium-weight packages or components on conveyor lines.
Clamping & Fixturing
Use this cylinder in jigs and fixtures where a 95 mm stroke provides sufficient travel to clamp workpieces for machining or assembly.
Gate & Diverter Actuation
Reliable double-acting operation and adjustable cushioning suit it for opening and closing small gates or diverters in material handling.
Is the Airtac SC50 Standard Cylinder SC50X95 the Right Cylinder?
For applications needing slightly more force, stepping up to the 63 mm bore (1559 N push at 0.5 MPa) is a natural progression. If space is the primary constraint, the 40 mm bore (628 N at 0.5 MPa) offers a smaller body. Always match replacement cylinders on five key points: bore (50 mm), stroke (95 mm), port thread (PT1/4), mounting accessory (basic), and magnet option (none).
At 95 mm stroke, the standard 20 mm rod is well-supported for axial loads. For any side-loading or non-axial force, use an external linear guide to protect the rod bearing from bending stress.
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 SC50X95 FAQ
At 0.7 MPa operating pressure, the SC50X95 produces a push force of 1374 N. The pull force at the same pressure is 825 N, accounting for the 20 mm rod area.
Yes, provided the original is a tie-rod cylinder matching the 50 mm bore, 95 mm stroke, PT1/4 port thread, basic mounting, and no magnet. The SC series is not dimensionally interchangeable with ISO 15552 profile cylinders.
