About the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X75-CA
The AirTAC MBL25X75-CA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces where a larger profile body cannot fit. It delivers a push force of 245 N and a pull force of 206 N at 0.5 MPa, making it well-suited for 75 mm travel tasks like indexing small trays or actuating lightweight gates. The riveted rolling-packed aluminum barrel keeps the overall footprint and weight to an absolute minimum, though the crimped construction means it is not designed to be rebuilt like a traditional tie-rod cylinder.
This specific SKU features a CA pivot (clevis) back cover, allowing the cylinder body to swing on a pin to accommodate arcing or angular loads during the stroke. Internally, a heterogeneous two-way piston seal retains grease for long service life, while the carbon steel piston rod features 20 um hard-chrome plating for wear and corrosion resistance. Because this configuration omits the -S suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor switch.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X75-CA Is Used
Textile Loom Guide
Actuates a 245 N push at 0.5 MPa to shift yarn guides laterally across a 75 mm path, using the CA clevis to absorb the slight angular arc of the loom carriage.
Sorter Diverter Arm
Swings a lightweight deflector flap on a packaging conveyor, where the 206 N pull force reliably retracts the arm and the pivot mount prevents binding under side load.
Parts Ejection Chute
Pushes small molded plastic components out of a machining cell into a collection bin, benefiting from the compact riveted aluminum body that fits within the machine's tight guard clearance.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X75-CA the Right Cylinder?
If you need less force, stepping down to the 20 mm bore yields 157 N of push at 0.5 MPa, while moving up to the 32 mm bore provides 402 N for heavier resistance. The base MBL relies on a fixed rubber bumper to soften end-of-stroke impact rather than an adjustable air cushion; choose the MBLC variant if your application requires cushion tuning for faster cycling or heavier moving masses. Additionally, a plain double-acting cylinder does not hold its load if air pressure is lost or the valve is centered—the rod will drift or drop, so an external rod lock or pilot-operated check valve is required for fail-safe position holding.
For this 75 mm stroke model, the CA pivot back cover is highly recommended over the default flat-end U type when the drive mechanism imposes slight angular misalignment. The 10 mm piston rod offers limited side-load tolerance, so if your mechanical linkage cannot be perfectly aligned, pair this clevis mount with an SDB pivot bracket or a rod knuckle. Replacement specifications: 25 mm bore, 75 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 MBL25X75-CA FAQ
This 25 mm bore cylinder has a G1/8 port and a 10 mm rod. It generates 245 N push and 206 N pull at 0.5 MPa, 343 N push at 0.7 MPa, and a maximum theoretical force of 50 kgf at 1.0 MPa.
No, the base MBL uses a fixed rubber bumper to absorb impact, not an adjustable cushion screw. If your application requires adjustable air cushioning for heavier loads or faster speeds, you must select the MBLC variant instead.
