About the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X40SCA
The AirTAC MBL40X40SCA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a robust 628 N push force at 0.5 MPa, making it well-suited for mid-range actuation tasks within a 40 mm stroke. The riveted rolling-packed barrel keeps the overall footprint and weight to an absolute minimum, prioritizing spatial efficiency over ISO 6432 interchangeability.
This specific SKU is configured with a built-in magnet (-S) for use with AirTAC CMSG, DMSG, and EMSG sensor switches to track rod position. It also features a CA pivot back cover, allowing the cylinder body to swing freely on a pin to accommodate arcing or angular loads. The carbon-steel piston rod is protected with 20 um hard-chrome plating, and the heterogeneous two-way piston seal retains grease for a long, low-maintenance service life.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X40SCA Is Used
Packaging Conveyor Diversion
Provides 628 N of thrust at 0.5 MPa to actuate routing gates on high-speed packaging lines, with the CA pivot absorbing slight misalignment during the stroke.
Textile Loom Tensioning
Uses the built-in magnet and CMSG reed switch to confirm yarn guide positioning, while the compact riveted barrel fits within the dense framework of weaving machinery.
Palletizing Stopper Arm
Halts loaded pallets on a transfer track by deploying a 40 mm stroke blocking pin, leveraging the 880 N push force available at 0.7 MPa for reliable braking.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X40SCA the Right Cylinder?
If you require slightly less force, the MBL32 bore steps down to 402 N push at 0.5 MPa, while stepping up to the MBL50 provides 981 N for heavier loads. Because this base MBL utilizes a fixed rubber bumper rather than an adjustable air cushion, applications involving fast cycling or heavy moving masses should consider the MBLC variant for end-of-stroke deceleration. Keep in mind that the rubber bumper only softens impact; it does not function as a lock. If your load must be held securely without live air pressure, you will need an external rod lock or a pilot-operated check valve to prevent drifting.
For this 40 mm stroke, side-load stress on the 16 mm rod is minimal. However, if your mechanism generates lateral thrust, the CA pivot back cover on this unit is highly advantageous, as it allows the cylinder to align dynamically with the load path. Replacement or matching units must specify a 40 mm bore, 40 mm stroke, G1/4 port size, PT thread, CA pivot back cover, and the -S magnet option.
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 MBL40X40SCA FAQ
At 0.5 MPa, this 40 mm bore cylinder provides 628 N of push force and 528 N of pull force. At 0.7 MPa, the push force increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa.
No, the base MBL features a fixed rubber bumper to soften end-of-stroke impact, not an adjustable cushion screw. If you need adjustable air cushioning for heavier or faster loads, you must specify the MBLC variant.
