About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X50SCA
The AirTAC MBLC63X50SCA is a compact double-acting aluminum mini cylinder engineered for high-force, short-stroke actuation. It generates 1558 N of push force and 1457 N of pull force at 0.5 MPa, peaking at a 318 kgf theoretical maximum at 1.0 MPa. The 50 mm stroke is ideal for heavy-duty clamping or ejection tasks where space is restricted but immediate power is required.
This variant features a screw-adjustable pneumatic cushion at both ends, allowing you to tune the end-of-stroke deceleration to protect the end covers from impact when moving heavy loads at high speeds. Unlike a fixed rubber bumper, this needle-bleed cushion smoothly decelerates the piston without locking it. The riveted rolling-packed aluminum barrel keeps the body light and compact, while the Ø16 carbon-steel rod with 20 um hard-chrome plating resists wear. The CA pivot back cover swings on a pin to accommodate arcing loads, and the built-in magnet (-S) supports CMSG, DMSG, and EMSG sensor switches for position detection.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X50SCA Is Used
Stamping Press Ejection
Uses the 1558 N push force at 0.5 MPa to knock heavy stamped metal blanks out of a die, relying on the tuned air cushion to silently stop the 50 mm stroke.
Pallet Diverter Arm
Leverages the CA pivot back cover to swing a heavy diverter gate on a packaging line, absorbing arcing loads while the magnet triggers a DMSG sensor.
Injection Mold Clamping
Secures heavy plastic injection mold halves within a tight machine envelope, using the 318 kgf theoretical maximum force to lock the part securely.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X50SCA the Right Cylinder?
Selecting the MBLC63X50SCA gives you the maximum standard bore in this mini-cylinder family, yielding 1558 N push at 0.5 MPa. If your application requires less force, stepping down to the 50 mm bore drops the output to 981 N push, which may suit lighter guiding tasks. As the largest available size, there is no larger standard MBL bore to step up to; for even greater thrust, a different ISO 15552 cylinder profile would be required. Choose this MBLC version over the base MBL when your 63 mm bore cycles heavy masses quickly and the fixed bumper cannot adequately absorb the kinetic energy.
This SKU is configured with a PT tapered port thread, an M14x1.5 rod-end thread, and a CA pivot back cover that naturally compensates for angular misalignment in arcing mechanisms. Because the -S magnet is fitted, you can mount CMSG reed or DMSG/EMSG electronic switches directly to the body. Note that the adjustable air cushion only decelerates the piston near the stroke ends; it does not hold position if air pressure is lost. For dead-load holding, an external pilot-operated check valve or rod lock is required.

- ✓ 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 MBLC63X50SCA FAQ
This 63 mm bore cylinder uses a Ø16 mm rod with an M14x1.5 rod-end thread and a G1/4 port. At 0.5 MPa it provides 1558 N push and 1457 N pull force. At 0.7 MPa the push increases to 2181 N. The theoretical maximum force is 318 kgf at 1.0 MPa.
The MBLC63X50SCA features a screw-tunable needle valve at both ends that traps a pocket of exhaust air to decelerate the piston before it hits the end cover. You adjust the needle to match your load and speed, which reduces impact noise and wear. It functions only as an end-of-stroke shock absorber, not as a braking or load-holding lock.
