About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X75CA
The AirTAC MBLC40X75CA is a double-acting aluminum mini cylinder with a 40 mm bore and 75 mm stroke. It generates 628 N of push force and 528 N of pull force at 0.5 MPa. A screw-adjustable pneumatic cushion at both ends decelerates the piston smoothly near stroke limits, absorbing impact on faster moves. This CA pivot variant features a clevis back cover that swings on a pin, accommodating arcing loads better than a rigid flat-end mount.
Built with a riveted rolling-packed aluminum barrel, the body stays compact and light for tight machine layouts. The 20 um hard-chrome plated carbon-steel rod pairs with a heterogeneous two-way grease-retaining piston seal to maintain lubrication over high cycle counts. Because this specific SKU lacks the -S magnet code, it cannot accept a CMSG, DMSG, or EMSG position sensor switch.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X75CA Is Used
Textile Loom Beater
Drives the beating mechanism at 628 N push force, using the CA pivot to accommodate the angular reed motion while the air cushion softens high-frequency stroke reversals.
Packaging Flap Folder
Folds cardboard flaps on a continuous flow wrapper; the 75 mm stroke delivers rapid extension while the tunable cushion prevents the mechanism from slamming at 800 mm/s.
Dosing Valve Lever
Actuates a pivoting diverter valve in a bulk powder line, swinging on the clevis pin to clear the arc while the 528 N pull force retracts the lever positively.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X75CA the Right Cylinder?
If your application requires less force, step down to the 32 mm bore offering 402 N push at 0.5 MPa. For heavier payloads, step up to the 50 mm bore providing 981 N push. Choose this MBLC over the base MBL when your cycle speeds or moving masses exceed what a fixed rubber bumper can safely absorb. The adjustable needle lets you tune end-of-stroke deceleration, though it is not a load lock; the rod will drift if air is lost. For a direct replacement, match the 40 mm bore, 75 mm stroke, G1/4 port, PT thread, CA pivot cover, and no magnet.
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 MBLC40X75CA FAQ
At 0.5 MPa, this 40 mm bore cylinder provides 628 N push and 528 N pull. At 0.7 MPa, it delivers 880 N push. The maximum theoretical force is 128 kgf at 1.0 MPa. It uses a G1/4 port with an M12x1.25 rod-end thread.
A screw-tunable needle at each end restricts exhaust flow to trap a pocket of air, decelerating the piston smoothly before it hits the end cover. You tune it to match your load and speed, which cuts noise and vibration on fast cycles. It only decelerates near the ends; it is not a brake and will not hold the rod if air pressure is lost.
