About the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X160CA
The AirTAC MBL40X160CA is a compact double-acting aluminum mini round cylinder engineered to deliver 628 N of push force and 528 N of pull force at 0.5 MPa. With a 160 mm stroke and a 40 mm bore, it bridges the gap between mid-size and heavy-duty small-frame actuators. The CA pivot back cover allows the body to swing on a pin, making it ideal for applications involving arcing or angular loads rather than rigid straight-line pushes. Because this specific SKU lacks the -S suffix, it cannot accept a position sensor; if detection is needed, an -S variant is required.
Built with a riveted rolling-packed aluminum barrel, the body is permanently crimped for light weight and a small footprint, meaning it is not designed to be disassembled like a traditional tie-rod cylinder. Inside, a heterogeneous two-way piston seal retains grease for extended cycle life, while the Ø16 mm carbon-steel piston rod features 20 µm hard-chrome plating to resist wear and corrosion. The end-of-stroke deceleration is handled by a fixed rubber bumper, which softens impact but is not an adjustable air cushion. For faster or heavier moving masses, the MBLC variant offers adjustable pneumatic cushioning.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X160CA Is Used
PCB Router Z-Axis
Drives the vertical plunge of a printed circuit board routing spindle, using the 628 N push force to cleanly cut through FR4 fiberglass substrates.
Automated Welding Torch
Swings a MIG torch into position using the CA clevis mount, allowing the cylinder to articulate smoothly along the curved joint of a chassis subassembly.
Carton Flap Folder
Actuates a mechanical arm to tuck minor flaps on packaging lines, where the 160 mm stroke provides the reach needed to clear varying box widths.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X160CA the Right Cylinder?
If your application requires less force, stepping down to the 32 mm bore yields 402 N of push at 0.5 MPa, while moving up to the 50 mm bore provides 981 N. This MBL40X160CA features a G1/4 port, PT thread form, a Ø16 mm rod with an M12x1.25 rod-end thread, and a CA pivot back cover. Keep in mind that a plain double-acting cylinder does not hold its load when air pressure is lost or the valve is centered—the rod will drift. The rubber bumper only softens end-of-stroke impact and is not a locking mechanism. If position holding is critical, use an external rod lock or a pilot-operated check valve.
At 160 mm of stroke, the unsupported length of the Ø16 mm rod increases its vulnerability to side-load bending. For this stroke length, relying on the CA pivot to accommodate angular misalignment is helpful, but for strict linear guidance, adding an external guide rail or switching to the MBLD double-rod cylinder is recommended to prevent premature bearing wear.
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 MBL40X160CA 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 the 1.0 MPa operating pressure limit.
No, the base MBL40X160CA uses a fixed rubber bumper to soften end-of-stroke impacts. It does not have an adjustable air cushion screw. If your load requires tunable deceleration for faster cycling, you should select the MBLC variant.
