About the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X200U
The AirTAC MBL25X200U is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. With a 25mm bore and 200mm stroke, it generates 245 N of push force and 206 N of pull force at 0.5 MPa. The U suffix designates a rigid flat-end rear cover for straightforward fixed mounting. This configuration uses a default PT tapered port thread and lacks a built-in magnet, meaning it cannot support position sensing.
Inside this riveted rolling-packed barrel, a heterogeneous two-way piston seal actively retains grease to maximize operational lifespan. The Ø10mm carbon steel piston rod features 20µm hard-chrome plating to resist wear and corrosion. End-of-stroke deceleration relies on a fixed rubber bumper rather than an adjustable cushion screw, which is sufficient for standard cycling speeds but differs from the MBLC variant.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X200U Is Used
PCB Shuttle Diverter
Routes populated circuit boards between SMT inspection lanes using 245 N of push force over the 200mm travel distance.
Connector Insertion Press
Drives a low-inertia ram to seat pin headers into plastic housings, relying on the rigid U flat-end mount for alignment.
Pouch Dispenser Gate
Opens small package flow-control gates in packaging lines where the compact riveted aluminum body fits within narrow frame clearances.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X200U the Right Cylinder?
If you need less reach, stepping down to the 20mm bore yields 157 N push at 0.5 MPa. For heavier drives, the 32mm bore provides 402 N push. Because this 200mm stroke is relatively long for a mini body, the small Ø10mm rod has limited side-load tolerance; use an external guide or pivot mount to prevent rod-bearing bending. Note that this SKU lacks the -S magnet, so CMSG, DMSG, or EMSG sensor switches cannot be fitted. If position feedback is required, select an MBL25X200S model. Finally, the fixed rubber bumper softens impact but does not lock the rod—air pressure must be maintained to hold a load vertically.
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 MBL25X200U FAQ
At 0.5 MPa it provides 245 N push and 206 N pull; at 0.7 MPa it delivers 343 N push. The maximum theoretical force is 50 kgf at 1.0 MPa. The port size is G1/8.
This specific SKU has no built-in magnet, so CMSG, DMSG, or EMSG switches cannot be installed. It uses a fixed rubber bumper for end-stop damping; for adjustable air cushioning, choose the MBLC variant.
