About the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X225SCA
The AirTAC MBL25X225SCA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. Operating at 0.5 MPa, it generates 245 N of push force and 206 N of pull force, making it well-suited for moving light payloads over a 225 mm stroke. Because this SKU includes the -S suffix, it has a built-in magnet for non-contact position detection using AirTAC CMSG reed or DMSG/EMSG electronic sensor switches.
Unlike rigid flat-end bodies, this specific configuration uses a CA pivot back cover, allowing the cylinder to swing freely on a pin to accommodate arcing or angular loads. The riveted rolling-packed aluminum barrel keeps the overall footprint minimal but is permanently crimped, meaning it cannot be disassembled for internal rebuilds like a traditional tie-rod cylinder. Impact at the end of stroke is absorbed by a fixed rubber bumper, not an adjustable cushion.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X225SCA Is Used
PCB Router Pivot Arm
Drives a 225 mm arcing swing arm on a light-duty PCB depaneling router, where the CA clevis accommodates the angular motion and the 245 N push force is sufficient to move the tool head.
Tote Flap Folder
Actuates a packaging flap-folding mechanism on a compact cartoner, using its 225 mm stroke to reach across small corrugated totes while fitting within a narrow 25 mm bore envelope.
Sample Tray Transfer
Indexes a diagnostic sample tray between testing stations, utilizing the built-in -S magnet to trigger a DMSG solid-state sensor for precise handoff positioning.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X225SCA the Right Cylinder?
If your application requires less force, stepping down to the 20 mm bore yields 157 N of push at 0.5 MPa. For heavier pushing, the 32 mm bore provides 402 N. The base MBL uses a fixed rubber bumper for end-of-stroke impact; if your payload requires deceleration control, upgrade to the MBLC variant for an adjustable air cushion. This cylinder does not hold its load when air pressure is lost or the valve is centered—the rod will drift. Use an external pilot-operated check valve if position holding is mandatory.
With a 225 mm stroke driven by a Ø10 mm rod, side-load tolerance is low. For this length, an external guide rail is strongly recommended to prevent rod-bearing bending. The CA clevis mount on this unit helps safely absorb angular misalignments. Replacement matching requires a 25 mm bore, 225 mm stroke, G1/8 port with PT thread, CA back cover, and the -S magnet.

- ✓ 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 (LB / FA / SDB) and back cover (CA pivot / U flat-end).
- check Installation by qualified personnel per AirTAC docs.
Airtac MBL Aluminum Alloy Mini Cylinder MBL25X225SCA FAQ
At 0.5 MPa, the push force is 245 N and the pull force is 206 N. At 0.7 MPa, the push force increases to 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa.
No, the base MBL features a fixed rubber bumper to soften end-of-stroke impact. It is not an adjustable air cushion. If your 225 mm stroke cycle requires variable deceleration, select the MBLC variant.
