About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X225SCA
The AirTAC MBLC25X225SCA is a double-acting aluminum mini cylinder generating 245 N of push force and 206 N of pull force at 0.5 MPa. A 225 mm stroke provides ample travel for mid-range positioning tasks. Equipped with a screw-adjustable pneumatic cushion at both ends, it smoothly decelerates the piston near stroke limits to absorb impact, reduce noise, and protect end covers during fast or frequent cycling. The riveted rolling-packed aluminum barrel keeps the body compact and lightweight for tight assembly spaces, while the 20 µm hard-chrome plating on the carbon-steel Ø10 mm rod defends against wear and corrosion.
This SKU includes a CA pivot/clevis back cover, allowing the cylinder to swing on a pin to accommodate arcing or angular loads without binding. The built-in magnet (-S) enables position detection using AirTAC CMSG (reed), DMSG, or EMSG (electronic solid-state) sensor switches. Its heterogeneous two-way grease-retaining piston seal maintains lubrication for a long service life across the 30-800 mm/s speed range.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X225SCA Is Used
Textile Loom Weft Insertion
Drives the weft insertion guide on a textile loom, using the 225 mm stroke to traverse the shed while the adjustable air cushion absorbs the rapid end-of-stroke reversal at 0.5 MPa.
Packaging Flap Folder
Folds cardboard flaps on a continuous packaging conveyor, where the CA pivot bracket accommodates slight misalignment and the cushioned ends reduce mechanical shock during 245 N tucks.
Bottle Sorting Diverter
Acts as a swing gate diverter on a bottle filling line, using the magnet for end-position confirmation and the pneumatic cushion to prevent jarring stops that could topple lightweight containers.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X225SCA the Right Cylinder?
Providing 245 N push at 0.5 MPa, this 25 mm bore suits moderate pushing and pulling tasks. If your application requires less force, step down to the 20 mm bore offering 157 N; if you need more power, step up to the 32 mm bore delivering 402 N. Choose this MBLC variant over the base MBL when operating at high cycling frequencies or moving loads where a fixed rubber bumper would wear out too quickly. Keep in mind the adjustable air cushion only decelerates the piston near the end of travel—it is not a load lock, so the rod will drift if air pressure is lost or the valve centers. For position holding without live air, add an external rod lock or pilot-operated check valve.
Replacement match: 25 mm bore, 225 mm stroke, G1/8 port, PT thread, CA pivot back cover, built-in magnet. Because the 225 mm stroke is relatively long for a small Ø10 mm rod, side-load tolerance is low; prevent rod bending by using an external guide rail, leveraging the CA pivot articulation, or selecting an MBLD double-rod cylinder for rigid support.
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 MBLC25X225SCA FAQ
At 0.5 MPa, the push force is 245 N and the pull force is 206 N. At 0.7 MPa, the push force increases to 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa.
A screw-tunable needle valve at both ends traps a pocket of exhaust air to decelerate the piston smoothly before it hits the end cover. You adjust the needle to match your specific load and speed, which cuts impact noise and vibration. It only decelerates near the stroke ends and does not lock or hold the load in place.
