About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X40SU
The AirTAC MBLC32X40SU is a double-acting, 32mm bore mini cylinder with a 40mm stroke, engineered for compact actuation where precise end-of-stroke control is required. Instead of a fixed rubber bumper, it features a screw-adjustable pneumatic air cushion at both ends. Tuning the needle decelerates the piston smoothly near the stroke limits, cutting impact shock and vibration on faster moves. At 0.5 MPa it delivers 402 N of push force and 346 N of pull force, making it well-suited for short, rapid positioning tasks.
This U-type variant uses a rigid flat-end back cover for direct mounting. The -S code indicates a built-in magnet, allowing position detection via AirTAC CMSG (reed), DMSG, or EMSG (electronic solid-state) sensor switches. The body utilizes a riveted rolling-packed aluminum barrel for a lightweight, space-saving footprint, while the 12mm carbon-steel rod features 20 µm hard-chrome plating to resist wear. A heterogeneous two-way grease-retaining piston seal maintains lubrication over a high cycle life.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X40SU Is Used
PCB Pick-and-Place
Drives a 40mm vertical pick head for surface mount components, using the tunable cushion to stop instantly without cracking delicate boards at 402 N force.
Carton Flap Folder
Actuates a short 40mm arm to tuck flaps on small packaging lines, where the adjustable air cushion prevents hard mechanical stops that loosen brackets over time.
Connector Insertion Press
Applies 346 N of pull force to seat electronic ribbon connectors, relying on the magnet and DMSG sensor to verify the exact 40mm retraction endpoint.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X40SU the Right Cylinder?
For lighter tasks requiring less than 346 N pull at 0.5 MPa, step down to the 25mm bore (206 N pull); if your fixture needs more power, step up to the 40mm bore (528 N pull). Choose this MBLC over the base MBL when your cycle speed or payload mass would prematurely wear a fixed rubber bumper. The 40mm stroke is highly rigid, but note that the 12mm rod offers low side-load tolerance; for any offset loads, use an external guide. As a replacement, match the 32mm bore, 40mm stroke, G1/8 port, M10x1.25 rod thread, PT thread form, U flat-end cover, and the -S magnet.

- ✓ 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 MBLC32X40SU FAQ
At 0.5 MPa, it provides 402 N push and 346 N pull force. At 0.7 MPa, push increases to 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
A screw needle at each end restricts the exhaust air as the piston nears the stroke limit, trapping a pocket of air to decelerate the load smoothly. You tune it to match the mass and speed, which protects the end covers from impact. It only decelerates near the ends and does not lock the rod; a plain cylinder will drift if air is lost.
