About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X150SU
The AirTAC MBLC63X150SU is a double-acting aluminum mini cylinder engineered for heavy-duty compact actuation. It delivers a robust 1558 N push and 1457 N pull at 0.5 MPa, utilizing a 63 mm bore and 150 mm stroke. The integrated -S magnet enables position detection via CMSG, DMSG, or EMSG sensor switches, while the U flat-end rear cover provides rigid, straight-line mounting. This model is built for rapid, repetitive cycles where substantial force is required in a confined footprint.
Unlike the base MBL series, this MBLC variant features a screw-adjustable pneumatic air cushion at both stroke ends. This allows you to precisely tune the end-of-stroke deceleration to match the load and velocity, absorbing kinetic energy to protect the end covers from impact damage during high-speed or high-mass moves. The riveted rolling-packed aluminum barrel keeps the body light and compact, while the 20 µm hard-chrome plated carbon-steel rod resists wear and corrosion for a long service life.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X150SU Is Used
Injection Mold Ejection
Provides the 1558 N push force needed to eject dense plastic parts from injection molds, using the tunable air cushion to prevent jarring impacts that could damage delicate mold features.
Pallet Diverting
Handles heavy pallets on packaging lines by smoothly decelerating the 150 mm stroke at high speeds, ensuring the 318 kgf peak capacity is harnessed without hammering the cylinder end covers.
PCB Pressing
Applies steady pressure for multi-layer PCB lamination presses, utilizing the -S magnet and DMSG electronic sensors to confirm rod extension within tight machinery spaces.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X150SU the Right Cylinder?
Selecting the MBLC63X150SU is optimal when your application demands high force and rapid cycling that exceeds the capabilities of smaller bores. Stepping down to the 50 mm bore reduces the 0.5 MPa push force to 981 N, which may be insufficient for heavier loads. Stepping up is not possible within this mini-cylinder range, as 63 mm is the largest available bore, offering a maximum theoretical output of 318 kgf at 1.0 MPa. Choose this MBLC cushioned version over the fixed-bumper MBL when moving substantial masses quickly, as the fixed rubber bumper cannot adequately absorb high-impact kinetic energy.
For exact replacement matching, this SKU features a 63 mm bore, 150 mm stroke, G1/4 port, PT thread form, U flat-end back cover, no additional mounting bracket, and a built-in magnet. Note that a plain pneumatic cylinder does not hold position when air is lost or the valve centers; the air cushion only decelerates the piston near the ends and acts as neither a lock nor a brake. If absolute position holding is required without live air pressure, an external rod lock or pilot-operated check valve must be fitted.

- ✓ 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 MBLC63X150SU 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 cushion is a screw-tunable pneumatic needle at both ends that traps exhaust air to decelerate the piston smoothly before it hits the end cover. You adjust the needle to match your specific load and speed, which is critical for high-velocity cycles where a fixed rubber bumper would fail. It only decelerates near the stroke ends and does not lock or hold the load.
