About the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X450-CA
The AirTAC MBL25X450-CA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers 245 N of push force and 206 N of pull force at 0.5 MPa, making it suited for moving light parts over a 450 mm stroke. The riveted rolling-packed barrel keeps the body light and small, though it is not designed to be disassembled and rebuilt like a tie-rod cylinder. Inside, a heterogeneous two-way piston seal retains grease for long service life, while the carbon-steel rod features 20 μm hard-chrome plating to resist wear and corrosion.
This specific SKU features a CA pivot (clevis) back cover that allows the cylinder body to swing on a pin, accommodating arcing or angular loads during movement. Because it lacks the -S suffix, a position sensor cannot be fitted to this unit. The end-of-stroke deceleration relies on a fixed rubber bumper, not an adjustable air cushion.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X450-CA Is Used
Textile Yarn Guide
Swings a yarn guide carriage across a 450 mm path. The CA pivot back cover absorbs the slight angular arcing as the carriage traverses, while the 245 N push force handles the light friction.
PCB Conveyor Sorter
Pushes populated PCB panels into a side-buffer lane. The compact aluminum body fits between tight conveyor frames, and the 206 N pull force easily retracts the diverter arm.
Packaging Flap Folder
Folds cardboard box flaps on a continuous motion packer. The fixed rubber bumper softens the fold impact without requiring manual cushion adjustment, keeping cycle times fast.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X450-CA the Right Cylinder?
If you need less reach, the MBL20X450-CA steps down to 157 N push at 0.5 MPa; if your payload is heavier, the MBL32X450-CA steps up to 402 N push. For faster or heavier moves requiring end-stroke tuning, select the MBLC variant for its adjustable air cushion. If you need spring-return action in a 20-40 mm bore, choose the MSBL or MTBL single-acting types. Note that this plain MBL does not hold its load when air pressure is lost or the valve is centered—the rod drifts or drops. The rubber bumper only softens impact; use an external rod lock or pilot-operated check valve to hold a load safely.
At a 450 mm stroke, the Ø10 mm piston rod is highly susceptible to bending under side loads. The CA pivot back cover helps manage minor angular misalignment, but for rigid radial loads you should add an external guide rail, pair the cylinder with an SDB pivot bracket, or switch to the MBLD double-rod anti-rotation type. Replacement match: 25 mm bore, 450 mm stroke, G1/8 port, PT thread, CA pivot back cover, 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 MBL25X450-CA FAQ
At 0.5 MPa, this 25 mm bore cylinder provides 245 N push and 206 N pull force. At 0.7 MPa, the push force increases to 343 N, with a theoretical maximum of 50 kgf at 1.0 MPa. It operates at speeds of 30-800 mm/s.
No, this specific SKU lacks the -S suffix, meaning a built-in magnet is absent and CMSG/DMSG/EMSG sensor switches cannot be fitted. Additionally, the base MBL uses a fixed rubber bumper for end-of-stroke impact absorption; for adjustable air cushioning, you must select the MBLC variant.
