About the Airtac SC50 Standard Cylinder SC50X250SCB
The SC50X250SCB is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa). Its 50 mm bore and 250 mm stroke suit medium-force clamping and positioning tasks. The built-in magnet allows CMSG/DMSG sensors to detect piston position directly on the tie-rod barrel.
This model includes a rear double clevis (CB) mount for pivoting attachment, supplied as accessory F-SC50CB. The 20 mm diameter piston rod and PT1/4 ports provide reliable pneumatic connections. The adjustable air cushion decelerates the piston smoothly at stroke end, protecting end caps during high-cycle operation.

Where the Airtac SC50 Standard Cylinder SC50X250SCB Is Used
Part Diverter
The 250 mm stroke and rear clevis mount allow the cylinder to pivot while pushing products off a conveyor line. Sensor magnets confirm end-of-stroke for reliable sorting.
Clamp Actuation
Delivers 1767 N at 0.9 MPa for secure workpiece clamping in machining fixtures. The double clevis mount handles the pivoting motion of a toggle clamp mechanism.
Hopper Gate Control
Operates a sliding gate on a seed or grain hopper. The magnetic piston enables remote position feedback to a PLC, ensuring the gate is fully open or closed.
Is the Airtac SC50 Standard Cylinder SC50X250SCB the Right Cylinder?
Select the SC50 bore for push forces around 982 N at standard plant pressure. If you need more force, step up to the SC63 (1559 N at 0.5 MPa); for a lighter, more compact solution, the SC40 delivers 628 N. This 250 mm stroke is well within the 1200 mm maximum standard stroke for bore 50.
For a drop-in replacement, match bore (50 mm), stroke (250 mm), PT port thread, CB rear double clevis mounting, and the built-in magnet (-S). The 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 SC50X250SCB FAQ
At 0.5 MPa, push force is 982 N and pull force is 825 N. At the maximum operating pressure of 0.9 MPa, push force reaches 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 cylinder. It is not dimensionally interchangeable. Only use it to replace another AirTAC SC tie-rod cylinder with identical bore, stroke, port thread, and mounting.
