About the Airtac SC50 Standard Cylinder SC50X275
The SC50X275 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 50 mm bore with a 275 mm stroke. At 0.5 MPa operating pressure, this cylinder generates a push force of 982 N and a pull force of 825 N, providing ample power for medium-duty linear actuation tasks. The 20 mm diameter piston rod and 21 mm adjustable air cushion at each end work together to deliver reliable, repeatable motion while softening end-of-stroke impact.
With a body length A of 150 mm, the total extended length of this configuration is approximately 425 mm. The standard PT1/4 port and M16x1.5 rod thread make integration straightforward. This model is supplied with the default TPU/NBR seals, rated for an operating temperature range of -20 to +70 °C, and does not include a built-in magnet or mounting accessories, giving you a clean base unit ready for custom fixturing.

Where the Airtac SC50 Standard Cylinder SC50X275 Is Used
Material Transfer
Ideal for pushing or diverting boxes and totes on a packaging line, where the 275 mm stroke provides a clean sweep across a conveyor width. The 982 N push force handles moderate-weight goods with ease.
Clamping & Pressing
Delivers controlled, consistent clamping force for assembly jigs or light pressing operations. The adjustable cushion allows for higher cycle rates by decelerating the load smoothly.
Gate & Valve Actuation
Suited for opening and closing hopper gates or actuating process valves. The tie-rod construction provides robust service in dusty or outdoor environments when properly ported.
Is the Airtac SC50 Standard Cylinder SC50X275 the Right Cylinder?
Select the SC50X275 when your application requires a force step up from the 32 mm bore (402 N push at 0.5 MPa) but does not yet demand the 1559 N output of the 63 mm bore. The 275 mm stroke is well within the 1200 mm maximum standard stroke for this bore, making it a standard, readily available configuration. For loads that involve significant side force or off-axis mounting, consider an external guide rail or a guided cylinder variant to protect the 20 mm rod from bending stress.
When replacing an existing cylinder, match five key points to ensure drop-in compatibility: the 50 mm bore, the 275 mm stroke, the PT1/4 port thread, the basic (no bracket) mounting style, and the absence of a magnet. This model is a direct replacement for another AirTAC SC50X275 or a compatible tie-rod cylinder with these exact specifications.
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 SC50X275 FAQ
At the standard 0.5 MPa operating pressure, the cylinder provides a push force of 982 Newtons and a pull force of 825 Newtons. The maximum push force at the 0.9 MPa operating limit is 1767 N.
This specific model (SC50X275) does not include a built-in magnet. To use CMSG/DMSG/EMSG sensors for position feedback, you would need to order the '-S' magnet variant (e.g., SC50X275-S).
