About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X40CA
The AirTAC MBLC25X40CA is a double-acting, compact aluminum mini cylinder engineered with a screw-adjustable pneumatic cushion at both stroke ends. Delivering 245 N of push force and 206 N of pull force at 0.5 MPa, it is built around a riveted rolling-packed barrel that keeps weight down while surviving tight machinery layouts. The 40 mm stroke moves quickly, and tuning the cushion needle ensures the piston decelerates smoothly before contacting the end covers, cutting impact shock and noise on repetitive cycles.
This SKU features a CA pivot (clevis) back cover that swings on a pin to accommodate arcing and angular loads, distinguishing it from rigid flat-end U models. It uses a Ø10 mm carbon-steel rod with 20 µm hard-chrome plating and a heterogeneous two-way grease-retaining piston seal for long service life. Note that this specific configuration omits the built-in magnet (-S), meaning it cannot host CMSG, DMSG, or EMSG electronic position sensors.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X40CA Is Used
Textile Loom Guide
Drives a 40 mm yarn guide arm on a weaving loom, using the tuned air cushion to soften the rapid directional changes and protect the pivot mechanism from shock.
Packaging Flap Folder
Pivots a cardboard flap-closing arm on a carton erector, where the CA clevis accommodates the arc of the folding motion and the cushion prevents end-cover banging.
Bottle Sorting Divert
Actuates a 245 N sorting gate for small PET bottles on a filling line, benefiting from the compact riveted body to fit between narrow conveyor tracks.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X40CA the Right Cylinder?
If your application requires less force, the Ø20 bore provides 157 N push at 0.5 MPa, whereas stepping up to the Ø32 bore yields 402 N. Choose this MBLC variant over the base MBL when your cycle speeds or moving masses exceed what a fixed rubber bumper can absorb. The CA clevis mounting is ideal for pivoting mechanisms, but remember that an air cushion only decelerates near the ends; it does not lock the rod. If position holding is required without live air pressure, fit an external rod lock or pilot-operated check valve. Replacement parts must match the 25 mm bore, 40 mm stroke, G1/8 port, PT thread, and CA pivot 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 MBLC Aluminum Alloy Mini Air Cylinder MBLC25X40CA FAQ
At 0.5 MPa, this 25 mm bore cylinder provides 245 N of push force and 206 N of pull force. At 0.7 MPa, the push increases to 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa.
No, because this specific SKU lacks the -S code for a built-in magnet. To use CMSG reed or DMSG/EMSG electronic switches for rod position detection, you must select an MBLC25X40S-CA variant that includes the internal magnet.
