About the Airtac SC50 Standard Cylinder SC50X40SCB
The SC50X40SCB is a 50 mm bore, 40 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. It delivers 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa), making it a compact yet powerful actuator for short linear movements. The 20 mm diameter piston rod and 21 mm adjustable air cushion ensure smooth deceleration even in rapid cycling applications.
This specific model includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke detection without external brackets. The CB suffix denotes a rear double clevis mount (F-SC50CB), providing a pivoting attachment at the cap end for applications requiring angular movement. Standard PT ports and TPU seals complete the configuration.

Where the Airtac SC50 Standard Cylinder SC50X40SCB Is Used
Part Diverter Gate
Short 40 mm stroke and rear clevis mount allow the cylinder to pivot a small diverter gate on a conveyor line, routing products between lanes with 982 N of push force.
Clamping Fixture
Delivers consistent clamping force for workholding in machining or assembly fixtures. The built-in magnet enables sensor confirmation of clamp engagement before cycle start.
Valve Actuator Linkage
The CB double clevis mount attaches to a lever arm for actuating ball or butterfly valves, providing reliable quarter-turn operation with adjustable cushioning at stroke ends.
Is the Airtac SC50 Standard Cylinder SC50X40SCB the Right Cylinder?
Choose the SC50X40SCB when your application needs a short 40 mm stroke with 982 N of force at standard plant pressure. If you require higher force, step up to the 63 mm bore (1559 N at 0.5 MPa); for lighter, faster movements, the 40 mm bore offers 628 N. The 40 mm stroke is well within the 50 mm bore's 1200 mm maximum standard stroke, so this is a standard catalog item.
To replace an existing cylinder, match five points: 50 mm bore, 40 mm stroke, PT port thread, rear double clevis (CB) mounting, and the built-in magnet (-S) for sensor compatibility. The SC is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC tie-rod 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 SC50X40SCB FAQ
At 0.5 MPa (approximately 73 psi), the 50 mm bore generates 982 N of push force on extension and 825 N of pull force on retraction. At the maximum operating pressure of 1.0 MPa, theoretical push force reaches 2000 N (200 kgf).
Yes. The -S suffix in the model code indicates a built-in magnet on the piston. This allows AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors to clamp directly onto the barrel tie-rods for non-contact position sensing.
