About the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X75SCA
The AirTAC MBL25X75SCA 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 well-suited for 75 mm stroke actuation in small part handling. The riveted rolling-packed barrel keeps the body light and small, though it is not designed to be disassembled like a tie-rod cylinder.
This specific SKU includes a CA pivot back cover, allowing the cylinder to swing on a pin for arcing or angular loads, and a built-in -S magnet for compatibility with AirTAC CMSG (reed), DMSG, and EMSG (electronic) sensor switches. The carbon-steel piston rod features a 20 um hard-chrome plating for wear resistance, paired with a heterogeneous two-way piston seal that retains grease for long service life.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X75SCA Is Used
Textile Loom Guide Arm
Swings a yarn guide arm through a 75 mm arc using the CA pivot back cover, leveraging the 245 N push force at 0.5 MPa to maintain tension in tight weaving frames.
PCB Depaneling Router
Pushes a depaneling blade through a 75 mm stroke on an electronics assembly line, using the built-in -S magnet and a DMSG solid-state switch to confirm cut completion.
Pharmaceutical Carton Flap
Folds a small carton flap in a compact packaging machine where space is restricted, relying on the 206 N pull force at 0.5 MPa to retract the actuator cleanly.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X75SCA the Right Cylinder?
If you need less force, the MBL20X75SCA offers 157 N push at 0.5 MPa, while stepping up to the MBL32X75SCA provides 402 N for heavier moves. The base MBL uses a fixed rubber bumper to soften end-of-stroke impact; if your application requires adjustable air cushioning for faster cycles, step up to the MBLC variant. Note that a plain MBL does not hold its position or load when air pressure is lost or exhausted—the rod drifts or drops, so use an external rod lock or pilot-operated check valve if position holding is required.
With a 75 mm stroke and a Ø10 mm rod, side-load tolerance is limited. For this CA pivot configuration, the clevis mounting naturally accommodates angular misalignment, but if you need strict linear anti-rotation, consider the MBLD double-rod type. This model uses a G1/8 port, M10x1.25 rod-end thread, and default PT port threads.
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 MBL25X75SCA FAQ
At 0.5 MPa, this 25 mm bore cylinder provides 245 N of push force and 206 N of pull force. At 0.7 MPa, the push force increases to 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa.
No, the base MBL25X75SCA uses a fixed rubber bumper to absorb end-of-stroke impact, not an adjustable air cushion. If your application requires adjustable cushioning for heavier loads, you should select the MBLC variant.
