About the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X40SCA
The AirTAC MBL25X40SCA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. Generating 245 N of push force and 206 N of pull force at 0.5 MPa, this 25 mm bore, 40 mm stroke unit is built for light-duty positioning. The riveted rolling-packed barrel crimps the front and back covers directly to the tube, creating a lightweight, sealed assembly that is not designed to be disassembled like a traditional tie-rod body.
This specific SKU includes a built-in -S magnet for rod position detection via CMSG, DMSG, or EMSG sensor switches, and features a CA pivot back cover. The CA clevis allows the cylinder to swing on a pin, accommodating arcing or angular loads. Internally, a heterogeneous two-way piston seal retains grease for long service life, while the Ø10 mm carbon steel rod features 20 µm hard-chrome plating to resist wear and corrosion.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X40SCA Is Used
PCB Pick-and-Place Gates
Actuates routing gates in compact electronics assembly lines, using the 245 N force to deflect populated boards between inspection stations.
Connector Insertion Arms
Provides the 40 mm stroke needed to press pin headers into housings, with the CA pivot absorbing slight angular misalignment during the press.
Pharmacy Drawer Latches
Locks and releases small automated dispensing drawers in medical cabinets, tracking open/close states via the integrated magnet and DMSG sensor.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X40SCA the Right Cylinder?
Select this 25 mm bore model when an application requires 245 N of push force at 0.5 MPa within a compact footprint. If you need less force, step down to the 20 mm bore which provides 157 N of push force. If your mechanism requires greater thrust, step up to the 32 mm bore which outputs 402 N. The base MBL uses a fixed rubber bumper to soften end-of-stroke impacts; if your cycle speed demands adjustable air cushioning, upgrade to the MBLC variant. Note that a plain MBL does not hold its position if air pressure is lost or the valve is centered, as the rubber bumper is not a locking mechanism. For exact replacement, match the 25 mm bore, 40 mm stroke, G1/8 port, PT thread, CA pivot back cover, and the -S 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 MBL25X40SCA FAQ
At 0.5 MPa, this 25 mm bore cylinder outputs 245 N of push force and 206 N of pull force. At 0.7 MPa, the push force increases to 343 N, with a theoretical maximum of 50 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
No, the base MBL25X40SCA features a fixed rubber bumper, not an adjustable cushion screw. If your application involves heavier moving masses or requires adjustable end-of-stroke deceleration, you should select the MBLC variant which includes adjustable air cushioning.
