About the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X250-CA
The AirTAC MBL32X250-CA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers 402 N of push force and 346 N of pull force at 0.5 MPa, making it well-suited for moving medium-weight components over a 250 mm travel distance. The riveted rolling-packed barrel keeps the body light and small, but the unit is not designed to be disassembled or rebuilt like a tie-rod cylinder.
This specific SKU features a CA pivot (clevis) back cover, allowing the cylinder body to swing freely on a pin to accommodate arcing or angular loads during motion. Because this model lacks the -S magnet suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor switch. The piston relies on a heterogeneous two-way seal that retains grease for long service life, while the carbon-steel rod features 20 µm hard-chrome plating to resist wear and corrosion.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X250-CA Is Used
Textile Loom Guide Arm
Drives a pivoting guide arm on a textile loom, utilizing the 402 N push force and CA clevis back cover to smoothly accommodate the angular arc of the thread guide mechanism.
Packaging Diverter Gate
Actuates a diverter gate on a packaging conveyor, where the 250 mm stroke provides ample travel to redirect cartons between sorting lanes in a compact footprint.
Bottle Casing Mechanism
Pushes empty bottles into cardboard cases on a beverage line, using the 346 N pull force to retract the diverter quickly while the rubber bumper absorbs the end-of-stroke impact.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X250-CA the Right Cylinder?
If you need less force, the MBL25 bore provides 245 N push at 0.5 MPa; for heavier moves, the MBL40 offers 628 N. The base MBL uses a fixed rubber bumper to soften end-of-stroke impact, but if your application requires adjustable air cushioning for faster cycling or heavier masses, step up to the MBLC variant. Keep in mind that a plain MBL does not hold its load if air pressure is lost or the valve is centered—the rod will drift or drop, so an external rod lock or pilot-operated check valve is required for position holding.
With a 250 mm stroke on a Ø12 mm rod, this cylinder has a low tolerance for side loads. To prevent rod-bearing bending and premature wear, use an external guide rail, rely on the CA pivot back cover to absorb angular misalignment, or switch to an MBLD double-rod type for anti-rotation. Replacement parts must match the 32 mm bore, 250 mm stroke, G1/8 port, PT thread form, and CA 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 MBL32X250-CA FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N push and 346 N pull force. At 0.7 MPa, the push force is 563 N, with a maximum theoretical force of 82 kgf at 1.0 MPa. The operating speed ranges from 30-800 mm/s.
No, this model has a fixed rubber bumper, not an adjustable air cushion (you would need the MBLC variant for that). Additionally, because this SKU lacks the -S magnet suffix, it cannot accept any CMSG, DMSG, or EMSG sensor switch for position detection.
