About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X400SCA
The AirTAC MBLC32X400SCA is a double-acting aluminum mini cylinder engineered for a 400 mm stroke. It generates 402 N of push force and 346 N of pull force at 0.5 MPa, making it well-suited for moving medium-weight components over extended distances. The riveted rolling-packed aluminum barrel keeps the body compact and lightweight rather than relying on a bulky rebuildable tie-rod assembly.
This variant features a CA pivot clevis back cover that swings on a pin to accommodate arcing or angular loads. A built-in magnet (-S) enables position detection using AirTAC CMSG, DMSG, or EMSG sensor switches. The screw-adjustable pneumatic cushions at both ends smoothly decelerate the piston near the stroke limits, absorbing kinetic energy to protect the end covers on long, rapid traverses.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X400SCA Is Used
Textile Loom Weft Insertion
Drives the weft insertion guide across a 400 mm loom bed, utilizing the 402 N push force and CA pivot to manage the slight angular arc of the rapier mechanism during high-speed weaving.
Packaging Pallet Divider Insertion
Extends 400 mm to push cardboard divider sheets between layers on a packaging conveyor, relying on the adjustable air cushion to halt the 563 N push force smoothly without crushing the product.
PCB Conveyor Transfer Arm
Moves populated PCB trays along a 400 mm transfer path, using the -S magnet and DMSG electronic sensor to confirm stroke completion before the next robotic pick.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X400SCA the Right Cylinder?
For applications needing less force, the 25 mm bore offers 245 N push at 0.5 MPa, while stepping up to the 40 mm bore provides 628 N push. Choose this MBLC cushioned version over the base MBL when your 400 mm traverse runs at high speed and the fixed rubber bumper cannot adequately absorb the impact. The PT tapered port, M10x1.25 rod thread, and CA clevis mount define the exact replacement match.
Because this 400 mm stroke generates significant side-load moments on the Ø12 mm rod, an external guide rail is strongly recommended to prevent rod bending. The CA pivot back cover helps absorb angular misalignment, but for purely linear loads requiring maximum rigidity, a double-rod MBLCD type should be considered. Remember that the adjustable air cushion only decelerates the piston near the stroke ends; it is not a brake and will not hold the load if air pressure is lost.
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 MBLC32X400SCA FAQ
At 0.5 MPa, the 32 mm bore provides 402 N of push force and 346 N of pull force. At 0.7 MPa, the push increases to 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa. It uses a G1/8 port, a Ø12 mm hard-chrome carbon steel rod with M10x1.25 end threading, and operates at speeds from 30-800 mm/s.
The cushion is a screw-tunable pneumatic needle at both ends that traps exhaust air to decelerate the piston smoothly before it hits the end cover. You tune the needle to match the load and speed, which cuts impact noise and vibration on the 400 mm stroke. It only decelerates near the ends and does not lock or hold the load without air pressure.
