About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X125CA
The AirTAC MBLC25X125CA is a double-acting aluminum mini cylinder engineered for compact spaces requiring controlled motion. It generates 245 N of push force and 206 N of pull force at 0.5 MPa. The 125 mm stroke is well-suited for mid-range traversing tasks. Unlike the base MBL, this MBLC variant features a screw-adjustable pneumatic air cushion at both ends. You tune the needle to smoothly decelerate the piston near stroke extremes, cutting end-cover impact, vibration, and noise during faster or heavier moves.
This SKU includes a CA pivot back cover that swings on a pin to accommodate arcing or angular loads, preventing rod binding. It uses a 10 mm carbon-steel rod with 20 µm hard-chrome plating and a heterogeneous two-way grease-retaining piston seal inside a riveted rolling-packed aluminum barrel. Because this specific code lacks the -S suffix, it has no built-in magnet and cannot host a CMSG, DMSG, or EMSG sensor switch for position detection.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X125CA Is Used
Textile Loom Weft Insertion
Drives the weft insertion mechanism on compact textile looms, using the 245 N push force and CA pivot to handle angular rod deflection during rapid traversing.
Bottling Line Diverter
Actuates a pivot-arm diverter gate on a 125 mm stroke to sort glass bottles, relying on the tuned air cushion to prevent sudden stops that could topple unstable containers.
Packaging Flap Folder
Folds cardboard carton flaps at high frequency, where the 206 N pull force retracts the rod and the adjustable cushion silences end-of-stroke knocking.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X125CA the Right Cylinder?
If you need less force, the 20 mm bore neighbor provides 157 N push at 0.5 MPa; if your load demands more, stepping up to the 32 mm bore yields 402 N. Choose this MBLC over the standard MBL when your cycle speeds or moved masses surpass what a fixed rubber bumper can safely absorb. The adjustable air cushion only decelerates near the ends—it is not a load lock, so the rod will drift if air is lost. For replacement, match bore 25, stroke 125, G1/8 port, PT thread, CA pivot cover, and no magnet. At 125 mm stroke, side-load risk is moderate, but the CA clevis naturally helps absorb angular misalignment.
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 MBLC25X125CA FAQ
At 0.5 MPa, this 25 mm bore cylinder delivers 245 N of push force and 206 N of pull force. At 0.7 MPa, the push force is 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa.
A screw-tunable needle at both ends traps a pocket of exhaust air to decelerate the piston smoothly before it hits the end cover. You adjust it to match your load and speed, which reduces impact wear and noise. It only decelerates near the stroke ends and does not lock or hold the load in place.
