About the Airtac SC50 Standard Cylinder SC50X37
The SC50X37 is a non-standard stroke AirTAC SC single-rod cylinder, built for applications needing a precise 37 mm linear movement from a 50 mm bore. At 0.5 MPa it generates 982 N pushing force, with a 20 mm diameter piston rod that resists bending in short-stroke tasks.
This double-acting tie-rod design uses filtered air and features an adjustable pneumatic cushion (21 mm length) at both ends to decelerate the piston quietly. The body length A is 150 mm, giving a compact extended length of approximately 187 mm. Ports are PT1/4 with an M16x1.5 rod thread for standard tooling attachment.

Where the Airtac SC50 Standard Cylinder SC50X37 Is Used
Short-Stroke Clamping
The precise 37 mm stroke and 982 N force at 0.5 MPa make the SC50X37 ideal for compact pneumatic clamps and holding fixtures where a full 50 mm stroke would over-travel.
Part Ejection
Delivers a quick, controlled 37 mm push to eject small parts from a die or mold. The adjustable cushion softens the end-of-stroke impact, protecting tooling.
Diverter Gate Actuation
Operates a small diverter flap on a conveyor line. The 20 mm rod and tie-rod construction handle the repetitive side-loading typical of gate mechanisms.
Is the Airtac SC50 Standard Cylinder SC50X37 the Right Cylinder?
Choose the SC50X37 when your work requires a short, non-standard 37 mm stroke with the 50 mm bore's 982 N push at 0.5 MPa. For higher force in a similar compact envelope, stepping up to a 63 mm bore provides 1559 N at the same pressure. If the 37 mm stroke is too short, the next standard SC50 stroke is 50 mm.
When replacing an existing cylinder, match five points exactly: 50 mm bore, 37 mm stroke, PT1/4 port thread, basic (no bracket) mounting, and no magnet. The SC is a tie-rod cylinder and is shorter than an ISO 15552 profile; it will only directly interchange with another AirTAC SC50 of the same stroke.
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 SC50X37 FAQ
At 0.7 MPa (7 bar) operating pressure, the SC50X37 produces a theoretical push force of 1374 N. The pull force on the retract stroke is 825 N at 0.5 MPa, due to the area reduction from the 20 mm piston rod.
No, 37 mm is a non-standard stroke for the 50 mm bore SC cylinder. The standard strokes start at 25 mm and then 50 mm. This SC50X37 is a made-to-order configuration, so lead time may be longer than a standard 50 mm stroke model.
