About the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X200SU
The AirTAC MBL25X200SU is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It provides 245 N push and 206 N pull force at 0.5 MPa from a 25 mm bore and 200 mm stroke. The U flat-end back cover provides a rigid fixed rear mounting face. An integrated -S magnet allows CMSG, DMSG, or EMSG electronic sensor switches to track rod position for end-of-stroke signaling.
Unlike tie-rod bodies, the MBL uses a riveted rolling-packed aluminum barrel with crimped front and back covers, keeping weight low but making the cylinder non-rebuildable. A heterogeneous two-way piston seal retains grease for long service life, while the carbon steel rod features 20 µm hard-chrome plating for wear and corrosion resistance. End-of-stroke impact is absorbed by a fixed rubber bumper, not an adjustable cushion.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X200SU Is Used
PCB Sorting Diverter
Uses the 245 N push force at 0.5 MPa to deflect populated PCBs between test lanes on a tight SMT line, where the 200 mm stroke provides full lane-clearing travel.
Carton Flap Folder
Actuates a folding blade on a compact packaging machine, relying on the riveted aluminum body's small footprint to fit between side conveyor rails.
Connector Press Head
Applies 206 N of pull force to seat electronic connectors onto a PCB, using the -S magnet and a DMSG solid-state switch to verify the press cycle completion.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X200SU the Right Cylinder?
This 25 mm bore yields 245 N push at 0.5 MPa. If you need less force, step down to the 20 mm bore (157 N push); if your load requires more, step up to the 32 mm bore (402 N push). The 200 mm stroke is well within the 500 mm standard limit, but the 10 mm rod has low side-load tolerance at this length. Use an external guide, a CA pivot back cover, or the MBLD double-rod type to prevent bending under offset loads.
The base MBL relies on a fixed rubber bumper, so choose the MBLC variant if you need adjustable air cushioning for heavier moving masses. A plain MBL does not hold its position if air pressure is lost or the valve is centered; the rod will drift. Use an external rod lock or pilot-operated check valve for fail-safe load holding. Replacement match: 25 mm bore, 200 mm stroke, G1/8 port, PT thread, U flat-end back cover, -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 MBL25X200SU FAQ
At 0.5 MPa, the 25 mm bore delivers 245 N push and 206 N pull force. At 0.7 MPa, push increases to 343 N, with a maximum theoretical force of 50 kgf at 1.0 MPa. The double-acting cylinder operates at speeds of 30-800 mm/s.
No, the base MBL25X200SU uses a fixed rubber bumper to soften end-of-stroke impact, not an adjustable cushion screw. If your application requires adjustable air cushioning for heavier loads or faster speeds, select the MBLC variant.
