About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X10SU
The AirTAC MBLC40X10SU is a double-acting aluminum mini cylinder engineered for very short 10 mm strokes, delivering 628 N of push force and 528 N of pull force at 0.5 MPa. A defining feature of this SKU is the -S code, meaning a built-in magnet is fitted for position detection. This allows you to mount CMSG reed switches or DMSG and EMSG solid-state sensors along the barrel groove. The U suffix denotes a rigid flat-end back cover for straightforward rear mounting.
Unlike the base MBL series which relies on a fixed rubber bumper, the MBLC utilizes a screw-adjustable pneumatic air cushion at both ends. This allows you to fine-tune the end-of-stroke deceleration, effectively reducing impact shock and noise on high-frequency indexing moves. The riveted rolling-packed aluminum barrel keeps the overall envelope compact for tight machinery, while the 20 µm hard-chrome plated carbon-steel rod resists scuffing. The cushion only decelerates near the stroke ends; it is not a load lock or brake.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X10SU Is Used
Pick-and-Place Grippers
Drives short 10 mm jaw movements on assembly pick-and-place heads, using the 628 N force to securely grip metal components during transfer.
Package Stops
Actuates as a high-speed lane diverter or stop gate on packaging conveyors, where the tunable cushion absorbs the rapid 10 mm impact at both ends.
Cassette Ejectors
Ejects filled product cassettes from tight machine slots, benefiting from the compact riveted barrel and DMSG sensor feedback to verify ejection.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X10SU the Right Cylinder?
With a 10 mm stroke yielding 628 N push at 0.5 MPa, this model suits very short, rapid transfers. If your application requires less force, stepping down to the 32 mm bore offers 402 N push, while moving up to the 50 mm bore provides 981 N push for heavier payloads. Because the stroke is extremely short, rod bending is minimal, but the 16 mm rod still has low side-load tolerance—always guide the load rigidly. The U flat-end cover provides a rigid rear mount, whereas a CA pivot cover would be chosen for arcing movements. Remember that a plain double-acting cylinder drifts if air pressure is lost; for true position holding without live air, install an external rod lock. The replacement match is: 40 mm bore, 10 mm stroke, G1/4 port, PT thread, U back cover, S magnet.
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 MBLC40X10SU 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, the push force increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa.
The MBLC40X10SU features a screw-tunable pneumatic needle at both ends. You adjust the needle to trap a small air volume that smoothly decelerates the piston near the stroke ends, preventing harsh impacts on fast cycles. It functions purely as a deceleration device and does not lock or hold the load in place.
