About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X25SU
The AirTAC MBLC63X25SU is a double-acting aluminum mini cylinder engineered for high-force, short-stroke tasks. It pushes with 1558 N and pulls with 1457 N at 0.5 MPa. Because the stroke is only 25 mm, this unit excels in tight spaces where a heavy mass must be moved rapidly and stopped without jarring the machine frame. The riveted rolling-packed aluminum barrel keeps the body light and compact, avoiding the bulk of a traditional tie-rod construction.
Unlike the base MBL which relies on a fixed rubber bumper, this MBLC variant features a screw-adjustable pneumatic cushion at both ends. You tune the needle to decelerate the Ø16 mm hard-chrome carbon-steel rod smoothly near each end, absorbing energy rather than crashing into the end cover. The built-in magnet (-S) enables position detection, while the U flat-end back cover provides a rigid, flush rear mount for straightforward installation.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X25SU Is Used
Stamping Pin Ejection
Uses the 1558 N push force to eject thick metal stampings from a press die in a 25 mm rapid burst, relying on the tuned cushion to prevent end-cover damage during high-frequency cycling.
Pallet Stopper Gate
Acts as a heavy-duty stop block for loaded pallets on a conveyor, where the short stroke and rigid U flat-end mount provide a solid barrier while the magnet confirms gate position.
Hydraulic Clamp Locking
Drives a short 25 mm hook to lock a hydraulic fixture in place, using the 1457 N pull force to secure the mechanism against vibration.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X25SU the Right Cylinder?
Select this 63 mm bore when you need substantial clamping or lifting force in a compact footprint. If you want to step down to save space and air consumption, the 50 mm bore provides 981 N of push force at 0.5 MPa. If you need even more power, note that 63 mm is the largest standard MBL/MBLC size, delivering a maximum theoretical output of 318 kgf at 1.0 MPa. Choose the MBLC over the standard MBL when your short-stroke cycle times are fast enough that a fixed rubber bumper would wear out quickly or transmit excessive shock to the machine. This SKU uses a G1/4 port, PT thread form, U flat-end back cover, and an -S magnet for CMSG, DMSG, or EMSG sensors. Remember that the adjustable air cushion only decelerates the piston near the stroke ends; it is not a brake, and the cylinder will not hold position if air pressure is lost.
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 MBLC63X25SU 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, with a maximum theoretical output of 318 kgf at 1.0 MPa. It uses a G1/4 port, a PT thread form, and features an M14x1.5 rod-end thread on its Ø16 mm hard-chrome plated carbon-steel rod.
The cushion is a screw-tunable needle valve at both ends that traps exhaust air to decelerate the piston smoothly before impact, which is critical for protecting the end covers on fast, heavy moves. It is not a locking brake. The -S designation means a built-in magnet is fitted, allowing you to mount CMSG (reed), DMSG, or EMSG (electronic) sensor switches along the body for precise end-of-stroke position detection.
