About the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X400-CA
The AirTAC MBL25X400-CA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a push force of 245 N at 0.5 MPa and a pull force of 206 N, making it well-suited for moving lighter components over its 400 mm travel range. The riveted rolling-packed barrel keeps the body light and small, but it is not designed to be disassembled and rebuilt like a traditional tie-rod cylinder.
This SKU features a CA pivot (clevis) back cover that swings on a pin to accommodate arcing and angular loads. Because the stroke exceeds 300 mm, the 10 mm carbon-steel rod is highly susceptible to side-load bending; the CA pivot helps mitigate this by self-aligning during movement. Note that this specific configuration lacks the -S magnet suffix, meaning it cannot accept a CMSG, DMSG, or EMSG sensor switch for rod-position detection.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X400-CA Is Used
Textile Loom Thread Guide
Drives a thread guide carriage along a 400 mm path, using the 245 N push force and CA clevis to accommodate the slight angular sweep of the weaving mechanism.
Packaging Sorter Diverter
Actuates a lightweight routing gate on a compact packaging line, where the aluminum body fits within the tight conveyor frame and the pivot rear absorbs side-load shifts.
Small Parts Bin Sweeper
Pushes empty plastic bins out of a filling station over a 400 mm reach, relying on the 206 N pull force to retract the sweeping arm quickly.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X400-CA the Right Cylinder?
If your application requires less travel, stepping down to the 20 mm bore neighbor provides 157 N of push force at 0.5 MPa, whereas moving up to the 32 mm bore yields 402 N for heavier pushing. The base MBL relies on a fixed rubber bumper to soften end-of-stroke impact; if your machine cycles rapidly with heavier masses, step up to the MBLC variant for an adjustable air cushion. Keep in mind that the rubber bumper is not a braking mechanism, and the cylinder will drift or drop if air pressure is lost or the valve is centered—use an external rod lock or pilot-operated check valve if the load must be held safely in place.
For a 400 mm stroke on a 10 mm rod, side-load tolerance is very low. Even with the CA pivot back cover, you should use an external guide rail to prevent rod-bearing bending, or switch to the MBLD double-rod type for anti-rotation and dual-side support. The exact replacement match for this unit is: 25 mm bore, 400 mm stroke, G1/8 port size, PT thread form, CA pivot back cover, and no 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 MBL25X400-CA FAQ
At 0.5 MPa, this 25 mm bore cylinder provides a 245 N push force and a 206 N pull force. At 0.7 MPa, the push force increases to 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa.
No, this specific SKU lacks the -S suffix for a built-in magnet, so a CMSG, DMSG, or EMSG sensor switch cannot be fitted. You must select an MBL25X400S-CA variant if you need electronic or reed switch position detection.
