About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X50SU
The AirTAC MBLC63X50SU is a double-acting, 63 mm bore mini cylinder with a 50 mm stroke, delivering a robust 1558 N push force at 0.5 MPa. It features a built-in magnet (-S) for position sensing and a rigid U flat-end back cover. Unlike the base MBL, this MBLC variant uses a screw-adjustable pneumatic air cushion at both stroke ends. You tune the needle to smoothly decelerate the piston, absorbing kinetic energy to protect the end covers on fast or heavy moves.
This model is built with a riveted rolling-packed aluminum barrel for a compact, lightweight body that fits tight spaces, rather than a bulky rebuildable tie-rod design. It uses a heterogeneous two-way grease-retaining piston seal and a 16 mm carbon-steel rod with 20 µm hard-chrome plating for wear resistance. The -S magnet supports AirTAC CMSG (reed), DMSG, and EMSG (electronic) sensor switches for precise end-of-stroke detection.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X50SU Is Used
Injection Mold Clamping
Provides 1558 N of push force at 0.5 MPa to secure small injection mold inserts, using the adjustable cushion to stop the 50 mm stroke smoothly without shocking the mold halves.
Pallet Diverter
Shifts heavy pallets on a packaging line where the 63 mm bore handles the mass, while the U flat-end cover mounts rigidly to the machine frame for precise lateral pushing.
Press Fit Bushings
Drives bronze bushings into automotive housings, relying on the DMSG electronic sensor to confirm the 50 mm stroke end-position and the cushion to prevent overshoot.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X50SU the Right Cylinder?
If you need less force, the 50 mm bore neighbor provides 981 N push at 0.5 MPa; stepping up is not possible as 63 mm is the largest mini size in this family. Choose this MBLC over the fixed rubber bumper of the standard MBL when cycling heavy 318 kgf loads at high frequency. Remember that the air cushion only decelerates near the ends and is not a brake; a plain cylinder will drift if air is lost, so add an external rod lock for fail-safe holding. This exact replacement match requires a 63 mm bore, 50 mm stroke, G1/4 port, M14x1.5 rod thread, PT port thread, U back cover, and the -S 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 MBLC63X50SU FAQ
At 0.5 MPa it provides 1558 N push and 1457 N pull. At 0.7 MPa it delivers 2181 N push. The maximum theoretical force is 318 kgf at 1.0 MPa operating pressure.
A screw-tunable needle at both ends traps exhaust air to decelerate the piston near the stroke limits. You adjust it to match the load and speed, reducing impact and noise on fast cycles. It only decelerates and does not lock the rod.
