About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X40SU
The AirTAC MBLC63X40SU is a double-acting aluminum mini cylinder engineered for compact spaces demanding high force, delivering 1558 N of push at 0.5 MPa. Its short 40 mm stroke is optimal for high-pressure clamping or ejecting heavy components within tight machinery envelopes. Unlike the base MBL series, this variant features a screw-adjustable pneumatic air cushion at both stroke ends, allowing you to fine-tune end-of-stroke deceleration to protect the end covers on heavy, fast moves.
This SKU includes a built-in magnet (S) for CMSG, DMSG, or EMSG sensor switches, enabling precise rod-position detection in automated sequences. The U flat-end back cover provides rigid rear mounting, while the riveted rolling-packed aluminum barrel keeps the unit lightweight. A heterogeneous two-way grease-retaining piston seal and a 20 µm hard-chrome plated carbon-steel rod ensure lasting friction-free operation even under dynamic loads.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X40SU Is Used
Injection Mold Ejection
Provides the heavy 1558 N push force needed to knock out dense plastic parts from injection molds, using the 40 mm stroke and tuned cushions to absorb the sudden end impact without damaging the tooling.
Stamping Press Feed
Indexes thick sheet metal blanks into a stamping press, relying on the compact riveted aluminum body to fit tight transfer spaces while the air cushion protects the end covers from heavy load rebound.
PCB Pressing Station
Applies steady downward clamping force on multilayer PCB lamination fixtures, utilizing the -S magnet and DMSG electronic switch to confirm the 40 mm stroke position for the control system.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X40SU the Right Cylinder?
Choose the MBLC63X40SU when your application requires substantial force in a minimal footprint. If you need less thrust, stepping down to the 50 mm bore yields 981 N of push at 0.5 MPa; if you require even more power, this 63 mm bore is the largest standard mini size available, providing a maximum theoretical 318 kgf at 1.0 MPa. The adjustable air cushion is essential here, as moving the mass associated with 1558 N of force at speed would quickly wear out a fixed rubber bumper.
This model uses a G1/4 port and an M14x1.5 rod thread, with a default PT tapered thread form and a U flat-end back cover. The -S magnet supports CMSG reed and DMSG/EMSG electronic switches. Note that while the cushions decelerate the piston smoothly, they do not lock the rod; a plain double-acting cylinder will drift if air pressure is lost. For external mounting, you can pair this rigid U cover with FA flanges, LB foot brackets, or SDB pivot brackets depending on your frame requirements.
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 MBLC63X40SU 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 maximum theoretical force is 318 kgf when operated at the 1.0 MPa pressure limit.
The MBLC63X40SU features a screw-tunable needle valve at both ends that traps a small amount of exhaust air to decelerate the piston before it hits the end cover. You adjust it to match your specific load and speed, which reduces impact noise and wear—unlike the non-adjustable fixed rubber bumper found on the standard MBL series.
