About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X400SU
The AirTAC MBLC32X400SU is a double-acting aluminum mini cylinder engineered for a 400 mm stroke, delivering 402 N of push force and 346 N of pull force at 0.5 MPa. A screw-adjustable pneumatic cushion at both stroke ends decelerates the piston smoothly, absorbing kinetic energy to protect the end covers on longer, faster traverses. The -S code denotes a built-in magnet for CMSG reed or DMSG and EMSG electronic sensor switches, while the U suffix specifies a rigid flat-end rear cover.
Unlike fixed-bumper designs, this model lets you tune the exhaust needle to match your specific load and velocity, cutting impact noise and vibration. The riveted rolling-packed aluminum barrel keeps the body compact and lightweight for tight machine footprints, while the Ø12 mm carbon-steel rod features a 20 µm hard-chrome plating paired with a heterogeneous two-way grease-retaining piston seal for low-friction longevity.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X400SU Is Used
PCB Panel Transfer
Pushes populated printed circuit boards along a 400 mm conveyor lane; the adjustable cushion ensures delicate solder joints are not jarred by sudden end-of-stroke stops.
Connector Insertion Press
Provides 402 N of precise downward force to seat multi-pin electronic connectors, using the DMSG electronic sensor to verify the exact insertion depth.
Carton Flap Folder
Actuates a 400 mm sweeping arm to fold small packaging flaps on high-speed cartoning lines, relying on tuned pneumatic cushions to handle rapid cycling.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X400SU the Right Cylinder?
Select this 32 mm bore when an application demands 402 N of thrust at 0.5 MPa across a 400 mm travel. If you need less force, step down to the 25 mm bore offering 245 N push; if moving heavier masses, step up to the 40 mm bore providing 628 N. The adjustable air cushion is specifically beneficial here over the base MBL because a 400 mm stroke builds significant piston speed, requiring tunable end-of-stroke deceleration rather than a simple rubber bumper.
Because this 400 mm stroke exceeds 300 mm, the relatively small Ø12 mm rod has lower tolerance for side loads and is susceptible to bending under lateral force. Manage this using an external guide rail, selecting a CA or SDB pivot bracket for arcing loads, or switching to an MBLD double-rod cylinder. Note that a plain double-acting cylinder does not hold position if air is lost or the valve centers; the rod will drift. Use an external rod lock or pilot-operated check valve for secure holding without live air. This exact replacement requires a 32 mm bore, 400 mm stroke, PT thread, U flat-end back cover, and the -S magnet.

- ✓ 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 MBLC32X400SU FAQ
At 0.5 MPa, this 32 mm bore cylinder generates 402 N of push force and 346 N of pull force. At 0.7 MPa, push increases to 563 N and pull to 484 N. The theoretical maximum force is 82 kgf at 1.0 MPa. It uses a G1/8 port, a Ø12 mm rod with an M10x1.25 thread, and operates at speeds between 30 and 800 mm/s.
The cushion is a screw-tunable needle valve at both ends that traps a small amount of exhaust air to decelerate the piston before it strikes the end cover. You adjust it to match the load and speed of your 400 mm stroke, which reduces impact noise and wear. It is strictly an end-of-stroke deceleration device and does not function as a load lock or brake.
