About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X15U
The AirTAC MBLC40X15U is a compact double-acting aluminum mini cylinder engineered for short 15 mm strokes. It delivers 628 N of push force and 528 N of pull force at 0.5 MPa, making it well-suited for high-impact clamping or pressing tasks in confined spaces. The riveted rolling-packed aluminum barrel keeps the body light and tight, while the 20 um hard-chrome plating on the carbon-steel rod protects against wear.
Unlike the base MBL which relies on a fixed rubber bumper, this MBLC variant features a screw-adjustable pneumatic air cushion at both ends. You can tune the needle to smoothly decelerate the piston near the stroke limits, significantly reducing end-cover impact and vibration on fast moves. Note that because this specific SKU lacks the -S suffix, it has no built-in magnet and cannot support CMSG, DMSG, or EMSG position sensors.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X15U Is Used
PCB Edge Connector Seating
Executes a rapid 15 mm press to seat electronic edge connectors with 628 N of force, using the tuned air cushion to prevent sudden impact damage to fragile PCBs.
Packaging Flap Tucking
Cycles quickly to tuck carton flaps on a high-speed packaging line, where the adjustable cushion absorbs the shock of the short 15 mm stroke stop.
Die Stamping Ejection
Provides a short, powerful 628 N ejection stroke in compact semiconductor or small-part die stamping machines, fitting into tight tooling gaps.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X15U the Right Cylinder?
Choose this 40 mm bore when you need substantially more force than the 32 mm variant (which offers 402 N push at 0.5 MPa) but want a smaller footprint than the 50 mm bore (providing 981 N push). The 15 mm stroke is ideal for very short, rapid transitions. The U flat-end back cover provides rigid, straight-line mounting. Step up to the 50 mm bore if your load exceeds 700 N, or down to 32 mm if spatial constraints are tighter.
Remember that the adjustable air cushion only decelerates the piston near the end of travel; it is not a locking mechanism. If your application requires the rod to hold position securely without continuous live air, you must integrate an external pilot-operated check valve or a dedicated rod lock.
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 MBLC40X15U FAQ
This 40 mm bore cylinder uses a G1/4 port and a Ø16 mm rod with an M12x1.25 thread. It generates 628 N push and 528 N pull at 0.5 MPa, 880 N push and 739 N pull at 0.7 MPa, with a maximum theoretical force of 128 kgf at 1.0 MPa.
No, this specific SKU does not have the -S code, meaning it lacks a built-in magnet. To use AirTAC CMSG, DMSG, or EMSG sensor switches for rod position detection, you would need to select the MBLC40X15SU variant instead.
