About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X40SCA
The AirTAC MBLC40X40SCA is a double-acting aluminum mini cylinder engineered for short, rapid linear moves. It generates 628 N of push force and 528 N of pull force at 0.5 MPa, making it well-suited for brisk 40 mm actuation tasks. Unlike the base MBL series, this variant features a screw-adjustable pneumatic cushion at both stroke ends. Tuning the needle valves lets you decelerate the payload smoothly, absorbing kinetic energy to protect the end covers rather than relying on a fixed rubber bumper.
This specific SKU includes a CA pivot back cover, allowing the cylinder body to swing on a pin to accommodate arcing or angular loads without binding. The riveted rolling-packed aluminum barrel keeps the envelope compact and lightweight for tight machine spaces, while the Ø16 mm carbon-steel rod features a 20 µm hard-chrome plating to resist scoring and corrosion. The integrated -S magnet enables position detection using AirTAC CMSG reed or DMSG and EMSG solid-state sensor switches.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X40SCA Is Used
Pick-and-Place Pivot Arms
Drives short 40 mm rotary pick-and-place arms via the CA pivot bracket, using the tunable cushion to gently stop fast 628 N swings without jarring delicate surface-mount components.
Package Sorting Diverter
Actuates a diverter gate on a packaging line, where the adjustable end-cushioning prevents the 528 N pull stroke from slamming the gate and loosening mechanical fasteners over time.
PCB Test Socket Clamping
Provides precise 40 mm clamping pressure against electronic test fixtures, utilizing the -S magnet with a DMSG solid-state sensor to confirm the 128 kgf maximum hold position.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X40SCA the Right Cylinder?
Select this 40 mm bore when your application requires more muscle than the 32 mm variant (which provides 402 N push at 0.5 MPa) but you want a smaller footprint than the 50 mm size (delivering 981 N push at 0.5 MPa). The 40 mm bore uses a G1/4 port and an M12x1.25 rod-end thread. The CA clevis mount is ideal for mechanisms where the load travels through an arc, preventing side-load damage. If your cycle speeds are slow and the mass is light, the standard MBL fixed bumper is adequate, but the MBLC cushion is necessary for high-frequency or heavy payloads. Note that the adjustable air cushion only decelerates the piston near the end of travel; it is not a brake and will not hold the rod in place if air pressure is lost or the valve centers. For dead-stop holding without live air, an external pilot-operated check valve or rod lock is required.
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 MBLC40X40SCA FAQ
This 40 mm bore cylinder uses a G1/4 port and an M12x1.25 rod thread. At 0.5 MPa it generates 628 N of push force and 528 N of pull force. At 0.7 MPa, push increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa operating pressure.
The MBLC40X40SCA traps a pocket of exhaust air at the end of both the extend and retract strokes. You turn a screw needle valve to regulate how fast this trapped air bleeds out, decelerating the piston smoothly. This is essential for protecting the CA pivot pin and end covers from high-impact shock, unlike a non-adjustable fixed rubber bumper.
