About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X30SU
The AirTAC MBLC63X30SU is a double-acting aluminum mini cylinder engineered with a screw-adjustable pneumatic cushion at both ends. Delivering a substantial 1558 N of push force at 0.5 MPa, this 63 mm bore unit is tailored for short, heavy-duty strokes. The 30 mm travel distance makes it highly effective for compact, high-impact positioning tasks where stopping a sizable load smoothly is critical.
This model features a built-in magnet (-S) for integration with CMSG reed or DMSG and EMSG solid-state sensor switches. It utilizes a heterogeneous two-way grease-retaining piston seal paired with a 20 µm hard-chrome plated carbon-steel rod. The riveted rolling-packed aluminum barrel keeps the body compact and lightweight, while the U flat-end back cover provides a rigid, default rear mounting interface.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X30SU Is Used
Press Fit Assembly
Drives a 1558 N press to seat bearings into automotive gearbox housings, utilizing the 30 mm stroke for rapid, repeatable short-travel insertion.
Pallet Stopper
Halts heavy loaded pallets on a packaging line, using the adjustable air cushion to absorb the 63 mm bore's kinetic energy without slamming the end cover.
PCB Router Clamping
Secures printed circuit board panels during routing operations, where the DMSG electronic sensor verifies the 30 mm clamp position for automated tooling.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X30SU the Right Cylinder?
When sizing this actuator, stepping down to the 50 mm bore reduces the push force to 981 N at 0.5 MPa, whereas moving up is not an option as 63 mm is the largest available bore in this series. Choose this MBLC variant over the standard MBL when your application cycles rapidly or moves a heavy mass, as the tunable needle decelerates the piston near the stroke ends to prevent end-cover damage. Remember that the air cushion only slows movement; it does not lock the rod. If you need to maintain position without live air pressure, install an external rod lock or a pilot-operated check valve. Replacement parts must match the 63 mm bore, 30 mm stroke, G1/4 port, PT thread, U back cover, and the magnetic sensor 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 MBLC63X30SU FAQ
At 0.5 MPa, this 63 mm bore cylinder provides 1558 N of push force and 1457 N of pull force. At 0.7 MPa, the push increases to 2181 N. The theoretical maximum output is 318 kgf at 1.0 MPa.
The cushion is a screw-tunable needle valve at both ends that traps air to decelerate the piston near the stroke limits. You adjust it to match the load and speed, which prevents end-cover impact on heavy moves. It functions strictly as a deceleration device, not a load lock or brake.
