About the Airtac SC50 Standard Cylinder SC50X575
The SC50X575 is a double-acting pneumatic cylinder with a 50 mm bore and a non-standard 575 mm stroke, built on the compact AirTAC SC tie-rod platform. At 0.5 MPa it provides 982 N of push force and 825 N of pull force, rising to 1767 N push at the maximum operating pressure of 0.9 MPa, making it a strong mid-bore actuator for extended linear movements.
This model uses a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 ports. The adjustable air cushion at each end (21 mm cushion length) decelerates the piston smoothly. The body length A is 150 mm, giving a total extended length of approximately 725 mm. Because the 575 mm stroke exceeds the 1200 mm maximum standard stroke for bore 50, this unit is a made-to-order configuration.

Where the Airtac SC50 Standard Cylinder SC50X575 Is Used
Long-Reach Part Transfer
The 575 mm stroke moves components between distant conveyor lanes or workstations. The 982 N push force at 0.5 MPa handles heavy pallets or engine parts reliably.
Vertical Lift Gate Actuation
Operates tall lift gates or hopper doors in agricultural and bulk-material handling. The adjustable cushion softens the stop at both ends, reducing wear on the gate structure.
Extended Press Ejection
Ejects formed parts from deep-draw or stamping presses where a long stroke is needed to clear the die. The 20 mm rod provides good column strength for straight-line pushing tasks.
Is the Airtac SC50 Standard Cylinder SC50X575 the Right Cylinder?
Choose the SC50 when your application needs more force than a 40 mm bore (628 N at 0.5 MPa) but does not require the 1559 N push of a 63 mm bore. The 50 mm bore strikes a balance between compactness and power for medium-duty automation. For this 575 mm stroke length, side-load management is critical: an unsupported 20 mm rod at full extension is vulnerable to bending under lateral forces. Use an external linear guide or a guided cylinder configuration to protect the rod bearing and piston seals.
When replacing an existing cylinder, match five key points: 50 mm bore, 575 mm stroke, PT1/4 port thread, basic (no bracket) mounting, and no magnet. This SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC50X575 FAQ
At 0.5 MPa the push force is 982 N and the pull force is 825 N. At 0.7 MPa push force increases to 1374 N, and at the maximum operating pressure of 0.9 MPa it reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf. Always use the force value that matches your regulated line pressure.
Only if the load is applied purely axially with zero side force. A 575 mm stroke with a 20 mm rod creates a long lever arm; any lateral load will bend the rod and damage the piston bearing. For side-loaded or unsupported loads, install an external guide rail or select a guided cylinder.
