About the Airtac SC50 Standard Cylinder SC50X42SCB
The AirTAC SC50X42SCB is a tie-rod double-acting cylinder delivering 982 N of push force at 0.5 MPa (1767 N at the 0.9 MPa max operating pressure). Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for the 42 mm non-standard stroke.
This configuration includes a built-in magnet (-S) for mounting CMSG/DMSG/EMSG sensors directly on the barrel, plus a rear double clevis (CB) mount for pivoting applications. The body length A is 150 mm, keeping the overall envelope compact for tight machine spaces.

Where the Airtac SC50 Standard Cylinder SC50X42SCB Is Used
Pivoting Linkage Actuation
The rear double clevis mount allows the cylinder body to pivot, making it ideal for actuating linkages on compact agricultural or construction equipment where the 982 N force at 0.5 MPa is sufficient.
Part Sorting Gate
With the built-in magnet for end-of-stroke sensing, this cylinder can reliably drive a small diverter gate on a conveyor line, confirming position before the next cycle.
Clamping Fixture
The 42 mm stroke provides a short, controlled clamping action. The adjustable cushion protects the fixture from impact, while the magnetic piston confirms the clamp is fully engaged.
Is the Airtac SC50 Standard Cylinder SC50X42SCB the Right Cylinder?
For applications needing more force, step up to the 63 mm bore (1559 N at 0.5 MPa). If a smaller footprint is required, the 40 mm bore provides 628 N at 0.5 MPa. The 42 mm stroke is non-standard; verify lead time for this made-to-order length.
To replace an existing cylinder, match five points: 50 mm bore, 42 mm stroke, PT port thread, rear double clevis mounting (F-SC50CB), and the built-in magnet (-S). The SC is a tie-rod design, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC cylinders with the same configuration.
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 SC50X42SCB FAQ
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
No. The SC50 is a double-acting cylinder that requires continuous air pressure to maintain position. If pressure is lost or the directional valve is centered, the piston can drift. For load holding, you must add an external rod brake or a pilot-operated check valve.
