About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X40CA
The AirTAC MBLC40X40CA is a double-acting aluminum mini cylinder with a 40 mm bore and 40 mm stroke. It delivers 628 N of push force and 528 N of pull force at 0.5 MPa. The CA back cover provides a pivot clevis that swings on a pin, making it ideal for arcing or angular load trajectories. Because this SKU lacks the -S suffix, it has no built-in magnet and cannot accept CMSG, DMSG, or EMSG position sensors.
Unlike the base MBL which relies on a fixed rubber bumper, this MBLC variant features a screw-adjustable pneumatic air cushion at both ends. You tune the needle to decelerate the piston smoothly near stroke limits, cutting impact shock and noise on faster cycles. The riveted rolling-packed aluminum barrel keeps the body compact for tight spaces, while the Ø16 mm carbon-steel rod features 20 µm hard-chrome plating to resist wear and extend seal life.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X40CA Is Used
Packaging Diverter Arms
Drives swinging diverter gates on packaging lines where the CA pivot clevis accommodates the arcing motion and the 628 N thrust at 0.5 MPa easily overcomes carton friction.
Textile Tensioning Frames
Regulates fabric tension on textile machinery, using the 40 mm stroke for fine adjustments while the adjustable cushion prevents sudden jerks that would tear delicate webs.
Palletizing Stop Gates
Actuates stop gates on low-profile pallet conveyors, fitting into tight frame gaps thanks to the compact riveted barrel while cushioning the 16 mm rod stop smoothly.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X40CA the Right Cylinder?
This 40 mm bore generates 628 N push at 0.5 MPa, sitting between the 32 mm bore (402 N push) and the 50 mm bore (981 N push). Step down to the 32 mm if your load is lighter, or step up to the 50 mm if you need higher thrust. Choose this MBLC over the fixed-bumper MBL when operating speeds are high enough that smooth end-of-stroke deceleration is required to protect the end covers.
The adjustable air cushion only decelerates the piston near the ends; it is not a load lock or brake. A plain MBLC will not hold position if air is lost or the valve centers, so add an external rod lock or pilot-operated check valve for fail-safe holding. For your replacement match: 40 mm bore, 40 mm stroke, G1/4 port, M12x1.25 rod thread, PT port thread form, CA pivot back cover, no magnet, and standard mounting.
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 MBLC40X40CA FAQ
At 0.5 MPa, this 40 mm bore cylinder provides 628 N push and 528 N pull force. At 0.7 MPa, it provides 880 N push and 739 N pull. The maximum theoretical force is 128 kgf at 1.0 MPa. It uses a G1/4 port, a Ø16 mm rod, and operates at speeds of 30-800 mm/s.
This specific SKU (MBLC40X40CA) lacks the -S suffix, meaning it has no built-in magnet and cannot accept CMSG, DMSG, or EMSG sensor switches. The adjustable air cushion at both ends is a screw-tunable pneumatic needle; you dial it in to decelerate the piston near the stroke ends, which reduces impact and vibration on fast moves. It is a deceleration device, not a mechanical lock.
