About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X100SU
The AirTAC MBLC40X100SU is a compact, double-acting aluminum mini cylinder engineered with a screw-adjustable pneumatic cushion at both stroke ends. Generating 628 N of push force and 528 N of pull force at 0.5 MPa, this 40 mm bore unit is built for rapid, heavier transitions where fixed rubber bumpers fail. The 100 mm stroke provides an optimal mid-range travel distance for assembly mechanisms.
This SKU features a built-in magnet (-S) for compatibility with AirTAC CMSG, DMSG, and EMSG sensor switches, enabling precise end-of-stroke detection. The U flat-end back cover provides a rigid rear mounting interface. Unlike tie-rod rebuildable bodies, its riveted rolling-packed aluminum barrel keeps the overall footprint tight, while the 20 µm hard-chrome plated carbon-steel rod resists wear against the heterogeneous two-way grease-retaining piston seal.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X100SU Is Used
CNC Vise Actuation
Provides 628 N of push at 0.5 MPa to clamp mid-weight aluminum castings inside CNC machining centers, using the tunable cushion to prevent end-cover slam on rapid 100 mm closures.
Pallet Diverter Arm
Swings heavy product flow between parallel conveyor lines; the 100 mm stroke moves the deflector gate fully while the adjustable air cushion absorbs the sudden mass at stroke completion.
Carton Flap Folder
Drives mechanical folder arms on continuous packaging lines, where the cushion needle dials out impact shock to protect the rigid U flat-end rear mount during high-frequency cycling.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X100SU the Right Cylinder?
Stepping down to the 32 mm bore drops the 0.5 MPa push force to 402 N, whereas moving up to the 50 mm bore increases it to 981 N. Choose this MBLC variant over the base MBL when your cycle speeds exceed the absorption limit of a fixed bumper, as the needle valves here decelerate the piston smoothly to protect the end covers. Remember that the adjustable air cushion only slows the rod near the stroke ends; it is not a brake, and the cylinder will drift if air pressure is lost or exhausted.
For a direct replacement, match the 40 mm bore, 100 mm stroke, G1/4 port, M12x1.25 rod-end thread, U flat-end back cover, and the -S internal magnet. The default PT tapered port thread is standard. Because the stroke is 100 mm, side-load bending stress on the Ø16 rod is minimal, but always verify rod-to-side-load alignment to maximize seal life.
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 MBLC40X100SU 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 maximum theoretical force is 128 kgf at 1.0 MPa.
The -S suffix indicates a built-in magnet for non-contact position detection using AirTAC CMSG (reed), DMSG, or EMSG (solid-state) sensor switches. The cushion is a screw-adjustable air cushion at both ends; you tune the needle to decelerate the load smoothly near the stroke ends, which is critical for high-speed moves that would destroy a fixed rubber bumper.
