About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X25SCA
The AirTAC MBLC63X25SCA is a compact, double-acting aluminum mini cylinder engineered for high-force, short-stroke automation. It delivers a robust 1558 N push and 1457 N pull force at 0.5 MPa, making this 25 mm stroke ideal for heavy, rapid clamping or ejection tasks. Unlike the standard MBL, this variant features a screw-adjustable pneumatic cushion at both ends to smoothly decelerate the piston near stroke extremes, absorbing impact without acting as a mechanical lock.
This configuration includes a CA pivot/clevis back cover designed to swing on a pin, accommodating arcing or angular loads that would bind a rigid mount. The riveted rolling-packed aluminum barrel keeps the body light and compact, while the Ø16 carbon-steel rod features 20 µm hard-chrome plating to resist corrosion and wear. The built-in magnet (-S) enables position detection using AirTAC CMSG, DMSG, or EMSG sensor switches.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X25SCA Is Used
Press Tonnage Ejection
Kicks heavy stampings out of a mechanical press bed using 1558 N of force over a fast 25 mm stroke, relying on the adjustable cushion to arrest the rod without slamming the end cap.
Pallet Diverting Arm
Drives a pivoting diverter arm on a packaging line where the CA clevis mount accommodates the angular swing while pushing heavy pallets at high cycle rates.
PCB Handler Clamping
Secures dense circuit board trays during rapid transfer between test stations, using the integrated magnet and a DMSG solid-state sensor to confirm clamp position.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X25SCA the Right Cylinder?
For applications needing less force, stepping down to the 50 mm bore yields 981 N push at 0.5 MPa; if 1558 N is insufficient, 63 mm is the largest standard mini size available in this series. Choose the MBLC over the base MBL when moving heavy masses at high speeds, as the fixed rubber bumper of the MBL cannot absorb the kinetic energy that this screw-tunable air cushion handles. Because this is a double-acting cylinder, it will drift if air is lost or the valve centers; use an external rod lock for fail-safe position holding.
Replacement match: 63 mm bore, 25 mm stroke, G1/4 port, PT thread, CA pivot back cover, built-in magnet (S).
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 MBLC63X25SCA FAQ
At 0.5 MPa, this 63 mm bore cylinder provides 1558 N push and 1457 N pull force. At 0.7 MPa, the push force is 2181 N, with a theoretical maximum of 318 kgf at 1.0 MPa. It uses a G1/4 port and a Ø16 mm rod with an M14x1.5 rod-end thread.
A screw-tunable needle valve at both ends traps a pocket of exhaust air to decelerate the piston smoothly before it hits the end cover. You dial the needle to match the load and speed, reducing noise and impact on fast, heavy strokes. It only decelerates near the ends and does not lock or hold the load in place.
