About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X400CA
The AirTAC MBLC40X400CA is a double-acting aluminum mini cylinder featuring a 40mm bore and 400mm stroke. It generates 628 N of push force and 528 N of pull force at 0.5 MPa. The CA back cover designates a pivot or clevis mount, allowing the body to swing on a pin to safely absorb angular motion during arcing strokes. This model lacks the -S suffix, meaning it is not equipped with a built-in magnet and cannot support CMSG, DMSG, or EMSG position sensors.
Unlike the base MBL series which relies on a fixed rubber bumper, this MBLC variant utilizes a screw-adjustable pneumatic air cushion at both ends. This mechanism allows you to tune the end-of-stroke deceleration to match your specific load and speed, effectively preventing end-cover impact on faster or heavier moves. The riveted rolling-packed aluminum barrel keeps the overall body compact and lightweight, while the Ø16 mm carbon-steel rod features 20 µm hard-chrome plating paired with a heterogeneous two-way grease-retaining piston seal for extended operational life.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X400CA Is Used
Textile Loom Beat-Up
Drives the loom's reed forward with 628 N at 0.5 MPa, using the CA clevis to absorb frame oscillation and the tuned air cushion to silently decelerate the 400mm stroke without jarring the warp threads.
Pallet Transfer Pusher
Indexes loaded pallets along a 400mm run where the 528 N pull retracts the rod smoothly, while the adjustable cushion prevents sudden stops that would shift the stacked goods.
Woodworking Drawer Assembly
Presses dovetail joints across a 400mm travel distance; the CA pivot accommodates minor frame misalignment, and the pneumatic cushion gently eases the clamp force to avoid marring soft pine.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X400CA the Right Cylinder?
At 0.5 MPa, this 40mm bore yields 628 N push and 528 N pull. If your application requires less force, stepping down to the 32mm bore provides 402 N push and 346 N pull. Conversely, if you need to move a heavier mass, the 50mm bore offers 981 N push and 881 N pull. Choose the MBLC over the standard MBL when your cycle speeds are high or the payload is significant enough that a fixed bumper cannot adequately absorb the kinetic energy. Note 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 or the valve centers.
This 400mm stroke utilizes a G1/4 port and an M12x1.25 rod thread. Because this stroke length approaches the maximum standard range of 500mm, the 16mm rod is highly susceptible to side-loading and bending under heavy off-center loads. To manage this, ensure an external guide rail supports the load, rely on the CA pivot bracket to absorb angular misalignment, or consider switching to an MBLCD double-rod cylinder to prevent rod deflection and twisting.

- ✓ 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 MBLC40X400CA FAQ
At 0.5 MPa, this 40mm bore cylinder provides 628 N of push force and 528 N of pull force. At 0.7 MPa, the push force increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa.
No, because the model code lacks the -S suffix, it is manufactured without a built-in magnet. You must select an MBLC40X400S variant if you need to mount CMSG reed or DMSG/EMSG electronic solid-state sensor switches for rod detection.
