About the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X350U
The AirTAC MBL25X350U is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a push force of 245 N and a pull force of 206 N at 0.5 MPa, making it suited for light-duty positioning across its 350 mm stroke. The riveted rolling-packed barrel crimps the front and rear covers directly to the tube, yielding a low-weight body that is not designed to be disassembled like a tie-rod cylinder.
This specific SKU features a U-type flat-end back cover for rigid fixed mounting and uses a default PT tapered port thread. Because it lacks the -S suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor. The carbon-steel piston rod is plated with 20 um of hard chrome to resist wear, while the heterogeneous two-way piston seal retains grease for a long service life.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X350U Is Used
Textile Loom Guide
Shifts a yarn guide carriage 350 mm across a narrow weaving loom, utilizing the 245 N push force to maintain tension without adding bulk.
Pallet Divert Arm
Extends a lightweight routing arm to push small electronics pallets off a main conveyor track within a 25 mm bore footprint.
Carton Flap Folder
Deploys a 350 mm sweep arm to fold corrugated carton flaps in compact packaging lines where a larger profile cylinder would not fit.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X350U the Right Cylinder?
Stepping down to the MBL20X350U drops the output to 157 N push at 0.5 MPa, while stepping up to the MBL32X350U increases it to 402 N. If your cycle requires end-position cushioning to absorb kinetic energy, select the MBLC variant with adjustable air cushioning instead of this base model. Note that the fixed rubber bumper only softens end-of-stroke impact; it is not a lock, so the rod will drift if air pressure is lost. At 350 mm, the Ø10 mm rod has low side-load tolerance—use an external guide or a CA pivot back cover to prevent rod-bearing bending.
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 MBL25X350U FAQ
At 0.5 MPa it provides 245 N push and 206 N pull; at 0.7 MPa the push increases to 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa. The operational speed ranges from 30-800 mm/s.
No. Because this SKU lacks the -S suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor. Additionally, the base MBL uses a fixed rubber bumper to soften end-of-stroke impact; for adjustable air cushioning, you must choose the MBLC variant.
