About the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X25SU
The AirTAC MBL32X25SU is a double-acting aluminum mini round cylinder engineered for tight machine spaces. Delivering 402 N of push force at 0.5 MPa, it suits compact ejection and clamping tasks. The riveted rolling-packed barrel permanently crimps the front and rear covers to the tube, creating a lightweight, low-profile body that is not designed to be disassembled like a traditional tie-rod cylinder. This specific SKU features a built-in magnet (-S) for use with AirTAC CMSG, DMSG, or EMSG sensor switches to track rod position. The U flat-end back cover provides a rigid, fixed rear mounting face for straight-line thrust. Inside, a heterogeneous two-way piston seal retains grease for long service life, while the Ø12 mm carbon-steel rod features 20 µm hard-chrome plating to resist wear and corrosion. It relies on a fixed rubber bumper to soften end-of-stroke impact rather than an adjustable air cushion.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X25SU Is Used
PCB Router Clamping
Provides 402 N of push force to secure PCB panels against a router fixture during high-speed depaneling, fitting easily into compact electronics machinery.
Packaging Carton Flap Folding
Uses its 25 mm stroke and U flat-end rigid mount to quickly fold small corrugated carton flaps, with the -S magnet confirming flap closure for the packaging line.
Connector Insertion Press
Drives delicate electronic pin connectors into housings, where the DMSG solid-state sensor detects the exact 25 mm end position to verify proper seating.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X25SU the Right Cylinder?
At 0.5 MPa, this 32 mm bore generates 402 N push and 346 N pull. If your payload is lighter, stepping down to the 25 mm bore yields 245 N push, while heavier loads require the 40 mm bore providing 628 N push. The fixed rubber bumper absorbs end-of-stroke impact, but it cannot hold a load in place if air pressure is lost or the valve is centered; the rod will drift. For applications requiring position holding without live pressure, add an external rod lock or a pilot-operated check valve. If your cycle speed creates heavy kinetic energy, step up to the MBLC variant, which offers adjustable air cushioning instead of the standard fixed rubber bumper. This SKU includes the -S magnet for CMSG / DMSG / EMSG switches, uses a G1/8 port with PT thread form, and mounts via its rigid U back cover.
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 MBL32X25SU FAQ
This double-acting 32 mm bore cylinder provides 402 N push and 346 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and a maximum theoretical force of 82 kgf at 1.0 MPa. It operates at speeds of 30-800 mm/s.
No, the base MBL uses a fixed rubber bumper to soften end-stop impact, not an adjustable air cushion (which requires the MBLC variant). Additionally, it does not hold a load if air pressure drops; use an external rod lock for fail-safe holding.
