About the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X135CA
The AirTAC MBL40X135CA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. Operating at 0.5 MPa, it provides 628 N of push force and 528 N of pull force, making it well-suited for mid-range actuation tasks requiring a 135 mm travel distance. The riveted rolling-packed barrel keeps the overall footprint and weight exceptionally low.
This specific SKU features a CA pivot (clevis) back cover, allowing the cylinder body to swing freely on a pin to accommodate arcing or angular loads. Because this configuration lacks the -S magnet suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor. The internal end-of-stroke deceleration relies on a fixed rubber bumper rather than an adjustable cushion screw.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X135CA Is Used
Textile Loom Beater
Drives the oscillating beater mechanism on a weaving loom, utilizing the CA pivot cover to smoothly accommodate the angular arcing motion across the 135 mm stroke.
Package Divert Arm
Actuates a pivoting diverter arm on a packaging conveyor, using 628 N of push force at 0.5 MPa to redirect cartons onto adjacent sorting lanes.
PCB Router Clamp
Applies mid-range holding pressure to secure printed circuit board panels during routing, relying on the 528 N pull force to retract the clamp quickly.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X135CA the Right Cylinder?
If you need less force, the MBL32 bore offers 402 N push at 0.5 MPa; for heavier drives, the MBL50 provides 981 N. The 135 mm stroke is below the 300 mm threshold where side-load bearing wear accelerates, but because the CA pivot back cover allows the body to swing, ensure the pin joint is greased to prevent binding. The Ø16 carbon-steel rod is hard-chrome plated for wear resistance.
For faster cycling with heavier loads, consider the MBLC variant which adds an adjustable air cushion. Note that the fixed rubber bumper on this base MBL only softens end-of-stroke impact; it does not hold the load. If the rod must remain fixed when air pressure is lost or exhausted, add an external pilot-operated check valve or a separate rod lock.
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 MBL40X135CA FAQ
At 0.5 MPa it delivers 628 N push and 528 N pull. At 0.7 MPa push is 880 N, with a maximum theoretical force of 128 kgf at 1.0 MPa. The port size is G1/4 with a PT thread form.
This specific SKU lacks the -S suffix, so a CMSG, DMSG, or EMSG sensor cannot be fitted. Additionally, the base MBL uses a fixed rubber bumper for end-of-stroke impact absorption; to get an adjustable air cushion, you must switch to the MBLC variant.
