About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X400SU
The AirTAC MBLC40X400SU is a double-acting, 40mm bore aluminum mini cylinder engineered with a screw-adjustable pneumatic cushion at both stroke ends. It yields 628 N of push force and 528 N of pull force at 0.5 MPa, making it well-suited for driving heavier fixtures over its 400 mm travel distance.
This configuration features a built-in magnet (-S) for compatibility with CMSG, DMSG, and EMSG sensor switches, alongside a rigid U-type flat-end back cover. The riveted rolling-packed aluminum barrel keeps the body compact and lightweight, while the 20 µm hard-chrome plated carbon-steel rod resists wear alongside the heterogeneous two-way grease-retaining piston seal.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X400SU Is Used
CNC Pallet Changer
Drives heavy machine tool pallets over 400 mm with 628 N push force, relying on the tuned air cushion to stop fully loaded pallets smoothly without shocking the linear rails.
Packaging Pusher Arm
Transfers heavy cardboard cartons between conveyor belts, using the 400 mm stroke and adjustable end-cushioning to maintain high cycle rates without end-cap damage.
Warehouse Sortation Diverter
Diverts totes at high speed in distribution hubs; the built-in magnet works with DMSG sensors to confirm full extension before the sorter retracts.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X400SU the Right Cylinder?
Stepping down to the 32mm bore neighbor provides 402 N of push force at 0.5 MPa, whereas moving up to the 50mm bore offers 981 N if your load requires greater thrust. Select this MBLC variant over the base MBL when your application runs at high speeds or cycles frequently, as the tunable needle decelerates the piston to prevent end-cover impact—something the fixed rubber bumper in the MBL cannot handle.
With a 400 mm stroke on a 16 mm rod, this cylinder has a low tolerance for side loads and is susceptible to rod bending over long extensions. To manage this, utilize an external guide rail, select a CA or SDB pivot mounting for arcing loads, or switch to an MBLD double-rod type. Note that the adjustable cushion only decelerates the piston near the ends; it is not a brake, and the rod will drift if air is lost or the valve centers.
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 MBLC40X400SU FAQ
At 0.5 MPa, it provides 628 N push and 528 N pull. At 0.7 MPa, push increases to 880 N. The theoretical maximum force is 128 kgf at 1.0 MPa.
The cushion features a screw-tunable needle at both ends that traps exhaust air to decelerate the piston smoothly near stroke limits, protecting the end covers on fast moves. The -S indicates a built-in magnet for position detection using CMSG reed or DMSG/EMSG electronic sensor switches.
