About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X15CA
The AirTAC MBLC63X15CA is a compact double-acting aluminum mini cylinder engineered for short, high-force linear motion. It produces 1558 N of push force and 1457 N of pull force at 0.5 MPa, peaking at a 318 kgf theoretical maximum at 1.0 MPa. Driven by a Ø16 mm carbon-steel rod with 20 µm hard-chrome plating, the 15 mm stroke is built for rapid, tight-travel power strokes. Unlike the base MBL which relies on a fixed rubber bumper, this MBLC variant features a screw-adjustable pneumatic cushion at both ends to decelerate the piston smoothly near stroke limits, cutting impact shock and noise on heavy fast moves.
This SKU uses a CA pivot (clevis) back cover that swings on a pin to accommodate arcing or angular loads, preventing rod binding during short-stroke power transfer. The body utilizes a riveted rolling-packed aluminum barrel for a lightweight, compact footprint that fits tight machine spaces without needing a rebuildable tie-rod assembly. It also employs a heterogeneous two-way grease-retaining piston seal for lasting lubrication. Note that because this specific configuration lacks the -S magnet code, it cannot accept a CMSG, DMSG, or EMSG position sensor switch.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X15CA Is Used
Short-Stroke Stamping
Drives a high-impact 1558 N stamping or marking head over a tight 15 mm travel, using the tunable cushion to soften the end-of-stroke strike and protect the tooling.
Pivot Gate Diverter
Leverages the CA clevis back cover to swing a heavy diverter gate on a packaging conveyor, allowing the cylinder to articulate safely without bending the rod.
Heavy Part Ejection
Ejects dense molded parts from a press in a confined space, relying on the 318 kgf peak force rating and compact riveted aluminum barrel to fit within tight machine tooling.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X15CA the Right Cylinder?
At 0.5 MPa, this 63 mm bore yields 1558 N push. If your application requires less force, the neighbouring 50 mm bore provides 981 N of push, stepping down nicely for lighter loads. Stepping up is not possible as 63 mm is the largest standard size in this mini-cylinder family. Choose this MBLC over the fixed-bumper MBL when your short 15 mm stroke cycles rapidly or moves enough mass that a rubber bumper would wear out or cause impact vibration. Keep in mind the adjustable cushion decelerates the piston near the end of travel but does not lock the rod; if you need to hold position without live air, install an external rod lock or pilot-operated check valve. Replacement match: 63 mm bore, 15 mm stroke, G1/4 port, PT thread, CA pivot cover, no magnet.

- ✓ 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 MBLC63X15CA FAQ
This 63 mm bore cylinder generates a push force of 1558 N and a pull force of 1457 N at 0.5 MPa. At 0.7 MPa, the push force increases to 2181 N. The theoretical maximum force is 318 kgf when operated at the maximum 1.0 MPa pressure.
The MBLC63X15CA uses a screw-tunable pneumatic needle at both ends to trap and bleed exhaust air, decelerating the piston smoothly before it hits the end cover. You tune the needle to match your load and speed, which reduces impact vibration and noise compared to a fixed rubber bumper. It only decelerates near the ends and does not function as a load-holding brake.
