About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X400CA
The AirTAC MBLC25X400CA is a compact double-acting aluminum mini cylinder engineered with a screw-adjustable pneumatic cushion at both ends. Delivering 245 N of push force at 0.5 MPa (206 N pull) through a 400 mm stroke, it is built for fast moves where a fixed rubber bumper would fail. The riveted rolling-packed aluminum barrel keeps the body light for tight spatial envelopes.
This SKU features a CA pivot/clevis back cover that swings on a pin to accommodate arcing loads, a critical attribute at this 400 mm extension length. It uses a heterogeneous two-way grease-retaining piston seal paired with a 20 µm hard-chrome plated carbon-steel rod. Because this specific code lacks the -S suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X400CA Is Used
Textile Loom Yarn Guide
Shifts a yarn guide carriage across a 400 mm path; the CA clevis absorbs angular rod stress while the adjustable cushion prevents end-cap shock during high-frequency loom cycling.
Packaging Flap Folder
Extends 400 mm to fold corrugated carton flaps at speed, using the tunable air cushion to softly decelerate the 245 N push force before impact, protecting the cardboard and mechanism.
PCB Depaneling Router
Drives a cutting head along a 400 mm axis for circuit board routing, where the compact 25 mm bore fits tight machine envelopes and the cushion eliminates bounce at stroke ends.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X400CA the Right Cylinder?
At 0.5 MPa, this 25 mm bore yields 245 N push and 206 N pull. If your load requires less force, stepping down to the 20 mm bore provides 157 N push (132 N pull). If you need more authority, stepping up to the 32 mm bore offers 402 N push (346 N pull). Choose this MBLC variant over the base MBL when cycling rapidly or moving enough mass that the impact on the end covers needs smooth, tunable deceleration rather than a fixed rubber stop.
Replacement match: 25 mm bore, 400 mm stroke, G1/8 port, PT thread, CA pivot back cover, no magnet. Because the stroke is 400 mm, the 10 mm rod is highly susceptible to bending under side loads; manage this by using the CA clevis with a spherical bearing, adding an external guide, or switching to an MBLD double-rod cylinder. Note that the air cushion only decelerates the piston near the stroke ends; it is not a brake and will not hold the rod in place if air pressure is lost or the valve centers.
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 MBLC25X400CA FAQ
This cylinder has a 25 mm bore and uses a G1/8 port. The output force is 245 N push and 206 N pull at 0.5 MPa, 343 N push at 0.7 MPa, and a maximum theoretical force of 50 kgf at 1.0 MPa.
This specific MBLC25X400CA SKU lacks the -S suffix, meaning it has no built-in magnet and cannot accept CMSG, DMSG, or EMSG sensor switches. The adjustable air cushion at both ends uses a screw needle to meter exhaust air, smoothly decelerating the piston near the stroke ends to reduce impact and vibration on fast moves; it is a dampener, not a load lock.
