About the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X25SCA
The AirTAC MBL32X25SCA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a push force of 402 N and a pull force of 346 N at 0.5 MPa, making it well-suited for short 25 mm linear actuation tasks. The riveted rolling-packed barrel keeps the body light and small, though it is not designed to be disassembled and rebuilt like a tie-rod cylinder.
This specific SKU includes a CA pivot back cover that swings on a pin to accommodate arcing or angular loads, rather than a rigid flat-end mount. It also features a built-in magnet (-S) for compatibility with AirTAC CMSG reed and DMSG or EMSG electronic sensor switches. The carbon-steel piston rod is plated with 20 µm hard chrome for high wear and corrosion resistance, while the heterogeneous two-way piston seal retains grease for a long service life.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X25SCA Is Used
PCB Router Z-Axis Pivot
Lifts and lowers a PCB depaneling router bit using its 402 N push force, while the CA pivot back cover absorbs slight angular misalignment during vertical plunging.
Semiconductor Wafer Gate
Actuates a short 25 mm access gate on a wafer processing tool, using the integrated magnet to trigger a DMSG solid-state sensor for precise open/close confirmation.
Carton Flap Folder
Folds small corrugated carton flaps in a compact packaging line where the 346 N pull force easily overcomes spring hinge resistance within a tight 25 mm stroke.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X25SCA the Right Cylinder?
If you need less force, step down to the 25 mm bore (245 N push at 0.5 MPa); if you require more power, step up to the 40 mm bore (628 N push at 0.5 MPa). The base MBL uses a fixed rubber bumper to soften end-of-stroke impact, so choose the MBLC variant if your application needs adjustable air cushioning for heavier or faster moving loads.
Because this is a double-acting cylinder, it does not hold its position or load when air pressure is lost or the valve is centered; the rod will drift or drop without live pressure. For drop prevention, use an external rod lock or a pilot-operated check valve. This exact replacement match features a 32 mm bore, 25 mm stroke, G1/8 port, PT thread, CA pivot back cover, and a built-in magnet.
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 (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 MBL32X25SCA FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 346 N of pull force. At 0.7 MPa, the push force increases to 563 N, with a maximum theoretical force of 82 kgf at 1.0 MPa. It operates at a speed range of 30-800 mm/s.
No, the base MBL features a fixed rubber bumper, not an adjustable air cushion; you must use the MBLC variant for adjustable air cushioning. Additionally, the rubber bumper only softens end-of-stroke impact and does not act as a lock, so the rod will drift or drop if air pressure is lost.
