About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X250CA
The AirTAC MBLC25X250CA is a double-acting aluminum mini cylinder featuring a 25 mm bore and 250 mm stroke. It generates 245 N of push force and 206 N of pull force at 0.5 MPa. A screw-adjustable pneumatic cushion at both ends decelerates the piston smoothly near stroke limits, absorbing kinetic energy to protect the end covers on longer, faster traverses.
This SKU specifies a CA pivot back cover, allowing the body to swing on a pin to accommodate arcing or angular loads. It uses a G1/8 port, a Ø10 mm hard-chrome carbon-steel rod with an M10x1.25 end thread, and a heterogeneous two-way grease-retaining piston seal. Because this configuration lacks the -S suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor switch.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X250CA Is Used
Textile Loom Yarn Guide
Swings a yarn guide across a 250 mm path. The CA pivot absorbs loom vibration while the adjustable cushion prevents abrupt snatching at 245 N push force.
Packaging Flap Folder
Arcs a mechanical arm to fold corrugated carton flaps. The clevis mount accommodates the pivoting geometry and the air cushion ensures soft end-of-stroke contact.
Bottling Line Diverter
Pushes glass containers onto a parallel processing lane. Tunable deceleration halts the 250 mm extension smoothly to avoid shattering fragile goods.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X250CA the Right Cylinder?
Stepping down to the 20 mm bore reduces output to 157 N push at 0.5 MPa, while stepping up to the 32 mm bore increases it to 402 N. Choose this MBLC variant over the fixed rubber bumper of the base MBL when cycling speeds or moving masses demand tunable end-of-stroke deceleration. The adjustable needle regulates exhaust flow to fine-tune the damping rate; it is strictly a deceleration device and will not lock the rod or hold position if air pressure drops.
At 250 mm of travel, the Ø10 mm piston rod is susceptible to bending under lateral stress. For this CA pivot configuration, ensure the clevis pin alignment is true to prevent side-loading, or integrate an external linear guide, switch to an SDB pivot bracket, or evaluate an MBLD double-rod cylinder to bear eccentric loads.
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 MBLC25X250CA FAQ
At 0.5 MPa it provides 245 N push and 206 N pull; at 0.7 MPa it provides 343 N push and 289 N pull. The maximum theoretical force is 50 kgf at 1.0 MPa. It uses a G1/8 port and an M10x1.25 rod-end thread.
No. This specific SKU lacks the -S magnet suffix, meaning no magnetic ring is fitted to the piston, so CMSG, DMSG, or EMSG sensor switches cannot detect rod position. You would need the MBLC25X250CAS variant for reed or electronic sensing.
