About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X450-100
The AirTAC MBLCJ40X450-100 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. It delivers 628 N of push force and 528 N of pull force at 0.5 MPa. The 100 mm rear adjustment yields a usable travel window of 350 to 450 mm, letting you fine-tune the end position without mechanical shims. A G1/4 port and Ø16 hard-chrome plated carbon steel rod handle the pneumatic flow for this bore size.
This SKU omits the built-in magnet, meaning it cannot accept AirTAC CMSG, DMSG, or EMSG position sensors. The riveted rolling-packed barrel and grease-retaining piston seal keep contamination out, while the tunable end-of-stroke cushioning safely decelerates heavy loads moving at up to 800 mm/s. Note that the rear stopper sets the travel limit but does not lock the load in place; external holding mechanisms are required for static positioning.

| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a margin.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X450-100 Is Used
Injection Mold Ejection
Provides the 628 N push force needed to eject dense plastic parts from molding machines, using the 100 mm stroke adjustment to precisely set the ejection reach without repositioning the cylinder.
Pallet Diverting Gate
Leverages the 450 mm travel to extend a diverting arm across a conveyor lane, while the dual adjustable air cushions absorb the kinetic energy of the heavy rod at high cycling speeds.
Sheet Metal Stacking
Pushes heavy sheet metal blanks into alignment racks, utilizing the 350-450 mm usable window to accommodate varying material widths on the fly.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X450-100 the Right Cylinder?
Choose this 40 mm bore when you need 628 N of thrust at 0.5 MPa. If your application is lighter, stepping down to the 32 mm bore yields 402 N of push force. If you need more power, the 50 mm bore provides 981 N. Compared to the MBLJ series, this MBLCJ model uses screw-tunable air cushions rather than a fixed rubber bumper, preventing end-cover damage during high-speed operations.
When replacing this cylinder, match the 40 mm bore, 450 mm stroke, 100 mm adjust code, G1/4 port, PT thread, and Basic/FA/LB mounting. Because the overall length is A + 2 x stroke + adjust, the extended 450 mm travel combined with the 100 mm adjuster creates a very long body. At this length, the 16 mm rod is susceptible to bending under lateral stress, so an external guide rail is strongly recommended to prevent side-load failures.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Adjustable window fits your end position
- ✓ Adjuster is a travel stop, not a lock
- ✓ Magnet (S) for sensors?
- ✓ Side load — add a guide on long strokes
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Set the rear stopper for the end position (a travel stop, not a lock).
- check Avoid side load; add an external guide on long strokes.
- check Mounting: Basic / FA flange / LB foot (no SDB, no back-cover code).
- check Installation by qualified personnel per AirTAC docs.
Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X450-100 FAQ
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, the push force increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa.
The 100 mm rear adjuster is strictly a travel stop that sets the 350-450 mm stroke window; it does not lock or hold the load pneumatically. The adjustable air cushion only governs end-of-stroke deceleration. Additionally, because this specific SKU lacks the -S magnet, it cannot be fitted with CMSG, DMSG, or EMSG position sensors.
