About the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X650SU
The AirTAC MBL25X650SU is a double-acting aluminum mini round cylinder engineered for tight spaces. It delivers 245 N push and 206 N pull at 0.5 MPa, with a 650 mm stroke that exceeds the 500 mm standard limit, making it a made-to-order unit for extended reach. The U flat-end back cover provides a rigid fixed rear mounting face. Equipped with a built-in magnet (-S), it supports CMSG, DMSG, and EMSG sensor switches for non-contact position detection.
Its riveted rolling-packed barrel crimps the covers directly to the tube, yielding a lightweight footprint that cannot be disassembled like a tie-rod body. A heterogeneous two-way piston seal retains grease for long service life, while the carbon-steel piston rod features 20 um hard-chrome plating to resist wear and corrosion. End-of-stroke energy is absorbed by a fixed rubber bumper rather than an adjustable cushion.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X650SU Is Used
Packaging Conveyor Diverter
Uses the 245 N push force at 0.5 MPa and 650 mm stroke to push cartons between parallel packaging lines where space is restricted.
PCB Shuttle Extraction
Extracts PCB trays from testing ovens; the built-in -S magnet triggers a DMSG electronic sensor to confirm full 650 mm retraction.
Vertical Parts Ejector
Ejects lightweight plastic moldings from a vertical press, relying on the 206 N pull force and U flat-end cover for rigid frame mounting.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X650SU the Right Cylinder?
At 0.5 MPa, this 25 mm bore generates 245 N of push force. If your application requires less force, step down to the 20 mm bore (157 N push); if you need more clamping or lifting power, step up to the 32 mm bore (402 N push). For faster or heavier moving masses at this extended stroke, consider the MBLC variant, which replaces the fixed rubber bumper with an adjustable air cushion to reduce end-of-stroke impact shock.
Because the 650 mm stroke is non-standard and exceeds 500 mm, the unsupported Ø10 mm rod is highly susceptible to bending under side loads. An external guide rail or a pivot mounting accessory is strongly recommended to prevent rod-bearing damage. Additionally, the base MBL cannot hold a load if air pressure is lost or the valve is centered; the rod will drift. Use an external pilot-operated check valve or rod lock for strict position holding. Direct replacement requires a 25 mm bore, 650 mm stroke, G1/8 port, PT thread, U back cover, and the -S 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 MBL25X650SU FAQ
This 25 mm bore cylinder has a G1/8 port. The theoretical force outputs are 245 N push and 206 N pull at 0.5 MPa, 343 N push at 0.7 MPa, and a maximum of 50 kgf at 1.0 MPa.
No, the base MBL uses a fixed rubber bumper to soften end impacts and does not have an adjustable cushion screw. If you need adjustable air cushioning for heavier loads, select the MBLC variant.
