About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X350CA
The AirTAC MBLC40X350CA is a compact double-acting aluminum mini cylinder featuring a screw-adjustable pneumatic cushion at both stroke ends. Delivering 628 N of push force at 0.5 MPa over a 350 mm travel, it is built for moving heavier masses at velocity where a fixed rubber bumper would fail. Tuning the cushion needle lets you decelerate the piston smoothly near the ends, cutting end-cover impact and vibration without acting as a load lock.
This configuration uses a CA pivot back cover that swings on a pin to accommodate arcing loads, paired with a riveted rolling-packed aluminum barrel for a lightweight, space-saving profile. The Ø16 mm carbon-steel rod features 20 µm hard-chrome plating, and a heterogeneous two-way grease-retaining piston seal maintains lubrication. Because this SKU lacks the -S suffix, it has no built-in magnet and cannot host a CMSG, DMSG, or EMSG position sensor.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X350CA Is Used
Textile Loom Beam Indexing
Drives the 350 mm indexing stroke on a weaving loom, relying on the 628 N push force to shift heavy warp beams while the adjustable cushion prevents jarring end-stop impacts at high cycling frequencies.
Packaging Line Diverter Arm
Actuates a pivoting diverter on a packaging conveyor, where the CA clevis accommodates the arc of the arm and the tunable air cushion safely decelerates the 40 mm bore at rapid cycle speeds.
Warehouse Carton Pusher
Pushes corrugated cartons across a roller conveyor over a 350 mm span; the 528 N pull force retracts the unit smoothly while the cushion needle is dialed in to minimize machine vibration.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X350CA the Right Cylinder?
Select this 40 mm bore when an application requires 628 N push force at 0.5 MPa with a long 350 mm stroke. If your move is lighter, stepping down to the 32 mm bore yields 402 N push, while stepping up to the 50 mm bore provides 981 N for heavier payloads. Choose this MBLC variant over the base MBL when cycling fast or moving sufficient mass that the fixed bumper cannot absorb the kinetic energy. As a direct replacement, match the 40 mm bore, 350 mm stroke, G1/4 port, PT thread, CA pivot cover, and confirm no magnet is required.
At 350 mm of travel, the Ø16 mm rod has limited tolerance for side loads. To prevent rod bending and premature seal wear, guide the load externally, rely on the CA clevis to absorb angular misalignment, or consider an MBLD double-rod cylinder for rigid anti-rotation guidance. Note that the adjustable air cushion only decelerates the piston near the end of stroke; it does not hold position if air pressure 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 MBLC40X350CA FAQ
This 40 mm bore cylinder uses a G1/4 port and a Ø16 mm rod with an M12x1.25 thread. At 0.5 MPa it provides 628 N push and 528 N pull. At 0.7 MPa it provides 880 N push and 739 N pull. The maximum theoretical force is 128 kgf at 1.0 MPa.
No. Because the model code lacks the -S suffix, this specific SKU is manufactured without a built-in magnet and cannot support CMSG, DMSG, or EMSG electronic or reed sensor switches. You would need the MBLC40X350S variant for position detection.
