About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X20CA
The AirTAC MBLC63X20CA is a compact double-acting aluminum mini cylinder engineered for high-force, short-stroke tasks. It generates 1558 N of push force and 1457 N of pull force at 0.5 MPa, peaking at a theoretical 318 kgf under 1.0 MPa. The 20 mm stroke is ideal for rapid clamping or ejection within confined machinery envelopes. Unlike fixed-bumper designs, this unit integrates a screw-adjustable pneumatic cushion at both ends to smoothly decelerate the piston, minimizing end-cover impact and vibration during rapid cycling.
This SKU features a CA pivot (clevis) back cover that swings on a pin to accommodate arcing or angular loads, preventing rod binding. The riveted rolling-packed aluminum barrel keeps the body lightweight and compact, while the Ø16 mm carbon-steel rod features 20 µm hard-chrome plating for wear resistance. Note that this specific configuration lacks a built-in magnet (-S), so it cannot host CMSG, DMSG, or EMSG position sensors.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X20CA Is Used
Injection Mold Ejection
Uses the 1558 N push force across a 20 mm stroke to knock finished plastic parts out of injection molds rapidly, with the air cushion absorbing the shock of frequent high-speed ejections.
Heavy Pallet Diverter
Employs the CA pivot clevis to swing a heavy diverter arm on a packaging conveyor, accommodating the angular load while the 63 mm bore provides firm, immediate redirection.
Pneumatic Press Crimping
Delivers fast, localized crimping force for wire terminals in a harness assembly machine, relying on the tunable cushion to soften the impact at the 20 mm stroke end.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X20CA the Right Cylinder?
Select this 63 mm bore when your application requires substantial force in a tight footprint. If you need less thrust, step down to the 50 mm bore, which yields 981 N push at 0.5 MPa; if you need to scale up, be aware 63 mm is the largest standard MBLC size, offering a maximum theoretical 318 kgf at 1.0 MPa. Choose the MBLC over the base MBL when cycling speeds are high enough that a fixed rubber bumper cannot adequately absorb the kinetic energy of the moving mass.
Because this SKU features the CA pivot cover, it is optimized for loads that travel through an arc rather than a strictly linear path. Keep in mind that the adjustable air cushion only decelerates the piston near the stroke ends; it is not a mechanical lock. If the assembly must hold position when air pressure is lost or exhausted, you must add an external rod lock or pilot-operated check valve. For replacements, match the 63 mm bore, 20 mm stroke, G1/4 port, PT thread, CA clevis back cover, and no-magnet configuration.
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 MBLC63X20CA FAQ
At 0.5 MPa, this 63 mm bore cylinder provides 1558 N push and 1457 N pull force. At 0.7 MPa, the push increases to 2181 N, with a maximum theoretical output of 318 kgf at 1.0 MPa. It uses a G1/4 port, a Ø16 mm rod, and an M14x1.5 rod-end thread.
The cushion is a screw-tunable needle at both ends that traps exhausting air to decelerate the piston smoothly near the stroke ends, which is superior to a fixed rubber bumper for heavy or fast loads. Because this specific CA-cover SKU lacks the -S magnet code, it cannot accept CMSG, DMSG, or EMSG position sensors.
