About the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X15SCA
The AirTAC MBL40X15SCA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. With a 40mm bore and 15mm stroke, it generates 628 N of push force and 528 N of pull force at 0.5 MPa. This specific SKU features a CA pivot back cover, allowing the cylinder body to swing on a pin to accommodate arcing or angular loads during short-stroke clamping.
Unlike tie-rod cylinders, the MBL uses a riveted rolling-packed barrel where the front and back covers are crimped to the tube, ensuring a lightweight but permanently sealed assembly. The carbon-steel piston rod features a 20 um hard-chrome plating for wear and corrosion resistance, while a heterogeneous two-way piston seal retains grease for a long service life. This model includes a built-in magnet (-S) for non-contact position detection using AirTAC CMSG, DMSG, or EMSG sensor switches. End-of-stroke energy is absorbed by a fixed rubber bumper, not an adjustable air cushion.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X15SCA Is Used
Packaging Forming Press
Ideal for driving short-stroke forming fingers on a packaging carton erecting machine, using the 628 N push force to crepe heavy cardboard while the CA pivot absorbs linkage misalignment.
PCB Router Clamp
Suitable for holding down PCB panels during routing operations, where the -S magnet works with a DMSG solid-state sensor to confirm clamp engagement before the spindle starts.
Diverter Gate Actuator
Fits into narrow conveyor frames to drive a sorting flap; the compact riveted aluminum barrel saves space while the CA clevis allows the gate to swing freely on its pivot pin.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X15SCA the Right Cylinder?
If you need slightly less force, step down to the 32mm bore (402 N push at 0.5 MPa); if you need more clamping power, step up to the 50mm bore (981 N push at 0.5 MPa). Choose the MBLC variant if your short-stroke impacts require adjustable air cushioning to soften end-of-stroke deceleration. For applications needing spring-return fail-safe movement, consider the MSBL or MTBL single-acting cylinders (available in 20-40mm bores).
This CA pivot configuration is ideal for linkages, but note that the fixed rubber bumper only softens end-of-stroke impact; it does not hold or lock the load if air pressure is lost. If your mechanism must maintain position during a pressure drop or valve centering, install an external rod lock or a pilot-operated check valve. The 15mm stroke keeps the unsupported rod length short, minimizing rod-bearing bending, but always ensure the pivot pin is aligned to prevent side-load wear on the 16mm rod.
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 MBL40X15SCA FAQ
This 40mm bore cylinder has a G1/4 port and a 16mm rod. It delivers 628 N push and 528 N pull at 0.5 MPa, 880 N push at 0.7 MPa, and a maximum theoretical force of 128 kgf at 1.0 MPa.
No, the base MBL uses a fixed rubber bumper to absorb impact at the end of the stroke and cannot be adjusted. If you need adjustable end-of-stroke deceleration for heavier loads, select the MBLC variant which features an adjustable air cushion.
