About the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X15SCA
The AirTAC MBL25X15SCA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. Operating at 0.5 MPa, it yields 245 N of push force and 206 N of pull force across its 15 mm stroke. The riveted rolling-packed barrel crimps the front and rear covers directly to the tube, yielding a lightweight body that is not designed to be disassembled like a standard tie-rod cylinder.
This specific SKU features a CA pivot back cover, allowing the cylinder body to swing on a pin to accommodate arcing or angular loads. The -S suffix denotes a built-in magnet for use with CMSG, DMSG, or EMSG sensor switches to track rod position. The Ø10 mm carbon-steel piston rod features 20 µm hard-chrome plating, and the heterogeneous two-way piston seal retains grease for extended operational life.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X15SCA Is Used
PCB Router Clamping
Provides 245 N of push at 0.5 MPa to hold printed circuit boards firmly against a machining fixture during high-speed routing operations.
Pouch Sealer Jaw
Drives the short 15 mm stroke on vertical form-fill-seal packaging equipment to close and crimp polymer film pouches with precise timing.
Textile Guide Arm
Utilizes the CA pivot back cover to swing a thread guide arm into position on a weaving loom, accommodating the angular arc of the mechanism.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X15SCA the Right Cylinder?
When sizing this 25 mm bore actuator, stepping down to the 20 mm bore reduces push force to 157 N at 0.5 MPa, while stepping up to the 32 mm bore increases it to 402 N. The 15 mm stroke is ideal for short, rapid clamping motions. Because the base MBL uses a fixed rubber bumper rather than an adjustable air cushion, select the MBLC variant if your application requires precise end-of-stroke deceleration for heavier moving masses.
Note that the standard MBL does not hold its position if air pressure is lost or the valve is centered; the rod will drift. For load-holding requirements, utilize an external rod lock or pilot-operated check valve. Replacement must match the 25 mm bore, 15 mm stroke, G1/8 port, PT thread form, CA pivot back cover, and the built-in magnet.
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 MBL Aluminum Alloy Mini Cylinder MBL25X15SCA FAQ
At 0.5 MPa, this 25 mm bore cylinder provides 245 N push and 206 N pull force. At 0.7 MPa, push force is 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a speed of 30-800 mm/s.
No, the base MBL features a fixed rubber bumper to soften end-of-stroke impact, not an adjustable cushion screw. If you need adjustable air cushioning for faster speeds or heavier loads, you must select the MBLC variant.
