About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X15CA
The AirTAC MBLC40X15CA is a compact double-acting aluminum mini cylinder engineered for very short-stroke actuation. It delivers a robust 628 N push and 528 N pull force at 0.5 MPa, making it well-suited for high-impact clamping or ejection tasks. Because this SKU lacks the -S suffix, it has no internal magnet and cannot host a CMSG, DMSG or EMSG position sensor.
Unlike the base MBL which relies on a fixed rubber bumper, this MBLC variant features a screw-adjustable pneumatic air cushion at both ends. Tuning the cushion needle allows you to decelerate the piston smoothly near each stroke end, which is critical for protecting the end covers on rapid, high-frequency cycles. The riveted rolling-packed aluminum barrel keeps the body light and compact, while the Ø16 mm hard-chrome carbon-steel rod resists wear thanks to a heterogeneous two-way grease-retaining piston seal.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X15CA Is Used
Stamping Press Ejection
Uses the 628 N push force to knock small stamped metal parts out of a die quickly, relying on the adjustable cushion to absorb the sudden end-of-stroke impact.
Sorter Diverter Arm
Executes rapid 15 mm jabs to deflect packages on a conveyor, where the CA pivot bracket accommodates the slight angular movement of the diverter linkage.
PCB Test Socket Clamp
Applies precise holding force on electronic test fixtures; the short stroke fits tight enclosures while the cushion prevents harsh vibrations from skewing delicate boards.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X15CA the Right Cylinder?
Select this 40 mm bore when you need substantially more force than the 32 mm size (402 N push at 0.5 MPa) but want to avoid the larger footprint of the 50 mm size (981 N push at 0.5 MPa). The 15 mm stroke is ideal for very compact, tight-space mechanisms. The CA pivot back cover is specifically designed to swing on a pin, accommodating arcing or angular loads that would bind a rigid flat-end mount. Note that the adjustable air cushion only decelerates the piston near the stroke ends; it is not a brake. A plain double-acting cylinder cannot hold position if air is lost or the valve centers, so an external rod lock or pilot-operated check is required for fail-safe holding. This configuration uses a G1/4 port, an M12x1.25 rod thread, and PT tapered port threads.
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 MBLC40X15CA FAQ
At 0.5 MPa, this 40 mm bore cylinder provides 628 N of push force and 528 N of pull force. At 0.7 MPa, push increases to 880 N. The theoretical maximum is 128 kgf at 1.0 MPa. It features a G1/4 port with PT tapered threads and an M12x1.25 rod-end thread.
No, because this specific SKU lacks the -S magnet suffix, it cannot accept CMSG, DMSG or EMSG sensor switches. The adjustable air cushion at both ends is tuned via a screw needle; it traps exhaust air to decelerate the piston smoothly near the stroke ends, reducing impact noise on fast cycles. It functions only as an end-of-stroke damper, not as a load lock.
