About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X30CA
The AirTAC MBLC63X30CA is a double-acting aluminum mini cylinder engineered with a screw-adjustable pneumatic cushion at both stroke ends. Delivering 1558 N of push force at 0.5 MPa, this 63 mm bore unit is built for rapid, heavy short-stroke cycles. The 30 mm stroke provides rapid transit for high-force clamping or ejection. A defining feature of this SKU is the CA pivot clevis back cover, which allows the body to swing freely on a mounting pin to accommodate angular misalignment and arcing loads.
Inside the riveted rolling-packed aluminum barrel, a heterogeneous two-way grease-retaining piston seal maintains lubrication over high-frequency cycles, while the Ø16 mm carbon-steel rod features 20 µm hard-chrome plating to resist scoring and corrosion. Because this configuration omits the -S magnet code, it cannot accept CMSG, DMSG, or EMSG position sensors. The adjustable cushioning is key here: it decelerates the piston smoothly near the ends, actively protecting the end covers from impact damage on heavy moves without acting as a load lock.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X30CA Is Used
Press Brake Tooling
Drives a 30 mm rapid clamping stroke holding heavy dies in a metal press, using the 1558 N push force and CA pivot to absorb angular deflection during off-center loads.
Pallet Diverter Arm
Actuates a heavy swing-arm deflector on a packaging conveyor, where the adjustable air cushion smoothly brakes the 63 mm piston at the 30 mm stroke end to prevent mechanical shock.
Injection Mold Ejection
Executes forceful short-stroke part ejection from an injection molding machine, leveraging the 318 kgf maximum theoretical force while the riveted aluminum body fits tight mold platens.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X30CA the Right Cylinder?
Stepping down from this 63 mm bore, the 50 mm neighbor yields 981 N of push force at 0.5 MPa, suitable if your payload is lighter. Stepping up is not possible within this mini-cylinder family, as 63 mm is the largest standard bore. Choose this MBLC variant over the fixed rubber bumper of the base MBL when your application runs at high speed or shifts a heavy mass, requiring tuned end-of-stroke deceleration to cut vibration. For replacement matching, verify the 63 mm bore, 30 mm stroke, G1/4 port, PT thread, CA pivot back cover, and the absence of a magnet. Note that a plain double-acting cylinder drifts when air is lost; the cushion only decelerates near the ends and does not hold position.
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 MBLC63X30CA FAQ
This model features a 63 mm bore, a G1/4 port, and an M14x1.5 rod-end thread. At 0.5 MPa it generates 1558 N of push force and 1457 N of pull force. At 0.7 MPa, push increases to 2181 N. The maximum theoretical force is 318 kgf at 1.0 MPa.
No, this specific SKU lacks the -S code, meaning it is manufactured without a built-in magnet and cannot host CMSG, DMSG, or EMSG sensor switches. You would need an MBLC63X30S variant for reed or electronic solid-state rod position detection.
