About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X40CA
The AirTAC MBLC63X40CA is a double-acting aluminum mini cylinder engineered for high-force, short-stroke automation. Delivering 1558 N of push force at 0.5 MPa (and up to 318 kgf at 1.0 MPa), it integrates a screw-adjustable pneumatic cushion at both ends to decelerate heavy loads smoothly, preventing end-cover impact on rapid cycles. The 40 mm stroke is ideal for compact, high-impact actuation where space is restricted but mass is significant.
This SKU features a CA pivot clevis back cover that swings on a pin to accommodate arcing and angular loads, preventing rod binding. It uses a Ø16 mm hard-chrome carbon-steel rod and a heterogeneous two-way grease-retaining piston seal for longevity. Note that because this specific configuration lacks the -S suffix, it cannot accept a CMSG or DMSG position sensor. The riveted rolling-packed barrel keeps the body compact and lightweight despite its substantial thrust.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X40CA Is Used
Stamping Press Ejection
Uses the 1558 N push force to knock heavy metal blanks from a stamping die, relying on the adjustable cushion to absorb the sudden impact at the 40 mm stroke end.
Pallet Diverter Arm
Actuates a heavy routing gate on a packaging line, where the CA pivot clevis accommodates the sweeping arc of the diverter mechanism without side-loading the rod.
Injection Mold Parting
Breaks the initial vacuum friction on a plastic injection mold, using the high 1457 N pull force at 0.5 MPa to separate heavy tooling halves over a short 40 mm distance.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X40CA the Right Cylinder?
Select this 63 mm bore when your application requires substantial force in a tight footprint; it provides 1558 N push and 1457 N pull at 0.5 MPa. If you need less force, stepping down to the 50 mm bore yields 981 N push, while stepping up is not possible as 63 mm is the largest standard MBL dimension. The adjustable air cushion is essential here over the fixed rubber bumper of the base MBL, as 318 kgf of theoretical max force demands tunable deceleration to protect the end covers. Because the CA pivot allows angular movement, ensure your mounting pin is greased to prevent wear. This cylinder will drift if air pressure is lost, as the cushion only decelerates and does not lock the rod.
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 MBLC63X40CA FAQ
This 63 mm bore cylinder uses a G1/4 port and a Ø16 mm rod with an M14x1.5 thread. At 0.5 MPa it provides 1558 N push and 1457 N pull. 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 suffix, meaning it is manufactured without a built-in magnet and cannot host a CMSG, DMSG, or EMSG sensor switch. If you require electronic or reed switch position detection, you must select the MBLC63X40S-CA variant.
