About the Airtac SC80 Standard Cylinder SC80X20SCB
The SC80X20SCB is a double-acting pneumatic cylinder delivering a push force of 2513 N at 0.5 MPa and up to 4523 N at 0.9 MPa, making it a compact power source for short, direct linear movements. Its 20 mm stroke, combined with a 25 mm diameter piston rod and 28 mm adjustable air cushion, provides a rigid, controlled motion ideal for clamping or ejecting in tight spaces.
This configuration 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-SC80CB), allowing the cylinder body to pivot during operation, which accommodates angular misalignment in lever or linkage applications.

Where the Airtac SC80 Standard Cylinder SC80X20SCB Is Used
Short-Stroke Clamping
The 20 mm stroke and 2513 N force at 0.5 MPa are ideal for pneumatic clamping fixtures in woodworking or metal fabrication, where a rapid, high-force hold is needed.
Part Ejection
Delivers a sharp, controlled push to eject parts from injection molds or stamping dies. The built-in magnet allows sensors to confirm retraction before the next cycle starts.
Linkage Actuation
The rear double clevis mount lets the cylinder pivot freely, perfect for actuating levers, diverters, or gates on packaging lines where the motion path is an arc.
Is the Airtac SC80 Standard Cylinder SC80X20SCB the Right Cylinder?
For applications requiring higher force, stepping up to the 100 mm bore SC100 series provides 3927 N at 0.5 MPa, while a step down to the 63 mm bore offers 1559 N. The short 20 mm stroke minimizes rod bearing stress, but any side load should still be managed with an external guide. When replacing, ensure a 5-point match: 80 mm bore, 20 mm stroke, PT port thread, CB rear double clevis mounting, and the built-in magnet for sensor compatibility.
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 SC80 Standard Cylinder SC80X20SCB FAQ
At the standard 0.5 MPa operating pressure, the push force is 2513 N and the pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 4523 N.
The CB suffix provides a rear double clevis bracket (F-SC80CB), which mounts to the cylinder's rear cap. This creates a pivoting anchor point, essential for applications where the cylinder rod must follow an arc or where the attached load is guided by a linkage rather than a linear rail.
