About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X400U
The AirTAC MBLC32X400U is a double-acting aluminum mini cylinder with a 32 mm bore and 400 mm stroke, delivering 402 N of push force at 0.5 MPa. Its riveted rolling-packed barrel keeps the body compact and lightweight for tight assembly spaces. A U flat-end back cover provides a rigid, straight-line mounting base. Because this SKU lacks the -S magnet suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor.
This variant uses a screw-adjustable pneumatic air cushion at both ends rather than a fixed rubber bumper. You tune the needle to smoothly decelerate the piston near each stroke end, absorbing kinetic energy to protect the end covers on fast or heavy moves. The 20 µm hard-chrome plated carbon-steel rod pairs with a heterogeneous two-way grease-retaining piston seal to maintain lubrication over long, high-frequency cycles. Note that the air cushion only decelerates near the ends; it is not a lock and the rod will drift if air is lost.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X400U Is Used
Textile Loom Weft Insertion
Drives the weft insertion guide across a 400 mm track at high frequency, using the tunable cushion to prevent end-cover impact on rapid reversals.
PCB Stencil Wipe Mechanism
Pushes a cleaning head through a 400 mm stroke over a stencil printer, relying on the rigid U flat-end mount to maintain parallel wiping pressure.
Carton Flap Folder
Folds packaging flaps on a continuous line where the 402 N push force secures the fold while the air cushion softens the end-of-stroke stop.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X400U the Right Cylinder?
If you need less reach, the 25 mm bore neighbor offers 245 N push at 0.5 MPa, while stepping up to the 40 mm bore yields 628 N. Choose this MBLC over the base MBL when your cycle speed or load mass outgrows a fixed rubber bumper. As a direct replacement match: 32 mm bore, 400 mm stroke, G1/8 port, PT thread, U flat-end back cover, no magnet. At 400 mm, the 12 mm rod has low side-load tolerance; use an external guide, a CA/SDB pivot, or an MBLD double-rod cylinder to prevent rod bending.
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 MBLC32X400U FAQ
At 0.5 MPa it provides 402 N push and 346 N pull. At 0.7 MPa it provides 563 N push. The maximum theoretical force is 82 kgf at 1.0 MPa.
A screw-tunable needle at both ends releases trapped air to smoothly decelerate the piston near stroke limits. You adjust it to match your load and speed, reducing impact and noise over a fixed rubber bumper. It only decelerates and is not a load lock.
