About the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X80U
The AirTAC MBL25X80U is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a 245 N push and 206 N pull force at 0.5 MPa, making this 80 mm stroke variant well suited for small part ejection or lightweight gating tasks. As a genuine AirTAC component, it features a Ø10 mm carbon steel piston rod protected by a 20 µm hard-chrome plating to resist wear and corrosion in dynamic applications.
This specific SKU utilizes a rigid U flat-end back cover for fixed rear mounting. The riveted rolling-packed barrel crimps the front and rear covers directly to the aluminum tube, keeping the footprint exceptionally light, though it is not designed to be disassembled like a traditional tie-rod cylinder. Because this model lacks the -S suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor. End-of-stroke deceleration relies on a fixed rubber bumper rather than an adjustable air cushion.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X80U Is Used
Electronic Component Ejection
Provides 245 N of push at 0.5 MPa to eject PCBs or small plastic housings from tight test fixtures without damaging delicate traces.
Pick-and-Place Gating
Actuates small diverter arms in semiconductor handling lines where the 80 mm stroke and lightweight aluminum body minimize moving mass.
Carton Flap Folding
Folds lightweight cardboard end-flaps on compact packaging machines, utilizing the 206 N pull force to retract the mechanism quickly.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X80U the Right Cylinder?
If you need slightly less force, the neighboring Ø20 bore provides 157 N of push at 0.5 MPa, whereas stepping up to the Ø32 bore yields 402 N for heavier resistance. The fixed rubber bumper handles standard cycle impacts, but choose the MBLC variant if your process requires an adjustable air cushion for heavier moving masses. Since this is a double-acting cylinder, it requires live air pressure to both extend and retract; it will not hold a load if air is lost or exhausted, so fit an external pilot-operated check valve if position retention is mandatory. This U flat-end rear mounts rigidly, and replacement requires matching the 25 mm bore, 80 mm stroke, G1/8 port, PT thread form, and no 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 MBL25X80U 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 reaches 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
This specific SKU lacks a built-in magnet, so CMSG, DMSG, or EMSG sensor switches cannot be fitted. Additionally, the base MBL uses a fixed rubber bumper for end-of-stroke impact absorption; if you need adjustable air cushioning to slow down heavier loads, select the MBLC variant instead.
