About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X20SU
The AirTAC MBLC32X20SU is a double-acting aluminum mini cylinder with a 32mm bore and 20mm stroke. It delivers 402N of push force and 346N of pull force at 0.5MPa, making it well-suited for short, rapid positioning tasks. Unlike the base MBL series, this MBLC variant features a screw-adjustable pneumatic air cushion at both ends. This allows you to fine-tune the end-of-stroke deceleration to match your load and speed, effectively dampening impact energy rather than relying on a fixed rubber bumper.
This specific configuration includes a U-type flat-end back cover for rigid mounting and a built-in magnet (indicated by the S in the model code). The magnet enables compatibility with AirTAC CMSG, DMSG, and EMSG sensor switches for precise end-position detection. The body utilizes a riveted rolling-packed aluminum barrel for a compact footprint, and the 12mm carbon-steel rod features 20μm hard-chrome plating to resist wear and corrosion.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X20SU Is Used
PCB Router Z-Axis
Drives a short 20mm plunge on a high-speed PCB depaneling router, using the adjustable cushion to prevent impact chatter on the spindle at 800mm/s.
Carton Flap Folder
Folds small corrugated carton flaps at 402N of push force, where the cushioned ends prevent crushing the paperboard during rapid cycling.
Tester Socket Actuator
Actuates an IC test socket with precise 20mm travel, relying on the integrated magnet and DMSG electronic sensor to verify seat position.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X20SU the Right Cylinder?
For applications requiring less force, stepping down to the 25mm bore yields 245N push at 0.5MPa, while moving up to the 40mm bore provides 628N push if your load demands more power. Choose this MBLC model over the standard MBL when your cycle speeds are high enough that the fixed rubber bumper cannot adequately absorb the impact. Note that while the adjustable cushion smoothly decelerates the piston near the stroke ends, it is not a braking device; the rod will drift if air pressure is lost or exhausted. To hold position without live air, an external pilot-operated check valve or a dedicated rod lock is required.
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 MBLC Aluminum Alloy Mini Air Cylinder MBLC32X20SU FAQ
At 0.5MPa, it provides 402N push and 346N pull force. At 0.7MPa, the push increases to 563N. The maximum theoretical force is 82kgf at 1.0MPa. It features a 32mm bore, a 12mm rod, an M10x1.25 rod-end thread, and a G1/8 port.
The MBLC32X20SU uses a screw-tunable needle valve at both ends to trap and exhaust air smoothly as the piston nears the end caps. You adjust the needle to match your specific load and speed, which decelerates the rod to minimize impact and noise. It only dampens the end of stroke; it does not lock or hold the load in place when air is removed.
