About the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X40CA
The AirTAC MBL25X40CA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a 245 N push force at 0.5 MPa across its 40 mm stroke. The CA pivot back cover allows the body to swing on a pin, making it ideal for arcing or angular load applications where a rigid flat-end mount would bind.
This variant lacks the -S suffix, meaning no built-in magnet is present and a position sensor cannot be fitted. It relies on a fixed rubber bumper to soften end-of-stroke impacts rather than an adjustable air cushion. The hardened carbon-steel piston rod features a 20 um chrome plating for wear resistance, paired with a heterogeneous two-way piston seal that retains grease for long service life.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X40CA Is Used
Transfer Arm Pivot
Ideal for driving a short 40 mm transfer arm on a packaging conveyor, using the CA clevis to swing parts smoothly into a loading nest with 245 N of push force.
PCB Component Press
Suits small electronics assembly machines where its 206 N pull force securely seats through-hole components onto printed circuit boards without crushing delicate leads.
Carton Flap Folder
Provides the compact stroke and pivoting angular movement needed to fold light cardboard flaps on a secondary packaging line in tight spatial constraints.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X40CA the Right Cylinder?
If you need less force, step down to the 20 mm bore (157 N push at 0.5 MPa); if 245 N is insufficient, step up to the 32 mm bore (402 N push). For faster or heavier cycling that requires end-of-travel deceleration, select the MBLC variant for its adjustable air cushion. If your mechanism must hold a load when air pressure is removed, note that this base MBL will drift or drop; install an external pilot-operated check valve or rod lock.
Replacement match: 25 mm bore, 40 mm stroke, G1/8 port, PT thread, CA pivot back cover, no magnet. Because this SKU lacks a magnet, CMSG, DMSG, or EMSG sensor switches cannot be used for position detection.
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 MBL25X40CA 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 is 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa.
No. The base MBL25X40CA uses a fixed rubber bumper to absorb end-of-stroke impact, not an adjustable air cushion (for that, choose the MBLC variant). Additionally, because this SKU lacks the -S suffix, it has no internal magnet and cannot be fitted with CMSG, DMSG, or EMSG position switches.
