About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X400SCA
The AirTAC MBLC40X400SCA is a double-acting, 40mm bore mini cylinder with a 400mm stroke, engineered for compact actuation where end-of-stroke impact control is critical. It generates 628 N of push force and 528 N of pull force at 0.5 MPa, stepping up to 880 N push at 0.7 MPa. The built-in magnet (-S) enables position detection using CMSG reed or DMSG and EMSG solid-state sensor switches. Unlike the base MBL, this variant uses a screw-adjustable pneumatic cushion at both ends to decelerate the piston smoothly, protecting the end covers during high-frequency or heavy-load traverses.
This 400mm travel model features a CA pivot/clevis back cover that swings on a pin to accommodate arcing or angular loads, a necessity for long-stroke mechanics. The riveted rolling-packed aluminum barrel keeps the body light and compact for tight spaces, while the Ø16 mm carbon-steel rod is plated with 20 µm hard chrome to resist wear and corrosion. A heterogeneous two-way grease-retaining piston seal maintains consistent lubrication over the 30-800 mm/s speed range.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X400SCA Is Used
Robotic Arm Wrist Extension
Drives the 400mm reach of a secondary robotic wrist axis, using the CA clevis to absorb angular misalignment while the adjustable cushion halts the 628 N load smoothly at full extension.
Pallet Transfer Pusher
Indexes packaging pallets along a 380mm stroke at high frequency; the tunable air cushion prevents end-cap shock on the 880 N @0.7 MPa push stroke, extending cylinder life.
Vertical Lift Gate Actuator
Raises and lowers a 40mm bore vertical sorting gate in a logistics hub, relying on the DMSG electronic sensor to confirm the 400mm fully extended position.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X400SCA the Right Cylinder?
For 40mm bore requirements, sizing up or down depends on your load: the smaller 32mm bore yields 402 N push at 0.5 MPa, while the larger 50mm bore provides 981 N push. Choose this MBLC40X400SCA over the fixed-bumper MBL when your cycle speeds are high enough that a rubber bumper would degrade or fail. The PT tapered port threads match the standard G1/4 porting for this bore size. Because this is a 400mm stroke, the 16mm rod is highly susceptible to side-load bending; always use an external linear guide or rely on the CA pivot bracket to prevent rod deflection. Note that the air cushion only decelerates the piston near the ends and does not lock the rod—if air is lost, the load will drift.
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 MBLC40X400SCA FAQ
At 0.5 MPa, this 40mm bore cylinder provides 628 N push and 528 N pull force. At 0.7 MPa, it delivers 880 N push and 739 N pull. The maximum theoretical force is 128 kgf at the 1.0 MPa operating pressure limit.
A screw-tunable needle at both ends restricts exhaust air flow near the stroke limits, decelerating the piston smoothly instead of a hard impact. You tune the needle to match your load and speed, which is superior to the fixed rubber bumper on the base MBL for fast or heavy 400mm moves. It only decelerates and does not lock the rod.
