About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X450-10S
The AirTAC MBLCJ40X450-10S is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and tunable air cushions at both ends. It delivers 628 N of push force and 528 N of pull force at 0.5 MPa. The 10 mm rear stopper creates a precise 440-450 mm usable travel window, ideal for applications requiring exact end-positioning over a long distance.
Unlike the fixed rubber bumper on an MBLJ, the screw-tunable cushions here decelerate heavy 450 mm moves safely. This -S SKU includes a built-in magnet for CMSG reed or DMSG/EMSG electronic sensors. Note the 16 mm carbon-steel rod with 20 um hard-chrome plating; at 450 mm of travel, external guidance is highly recommended to prevent rod bending under side loads.

The rear stopper sets the end position — it is a travel stop, not a lock. Overall length = A + 2 × stroke + adjustable stroke. MBLJ/MBLCJ mounting is Basic / FA / LB only (no SDB, no back-cover code). Thread options: PT / G / NPT.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 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 MBLCJ40X450-10S Is Used
Packaging Conveyor Diverter
Pushes heavy cartons across a 450 mm belt using 628 N of force, using the 10 mm stroke adjuster to dial in the exact push distance without moving the mount.
CNC Lathe Bar Feeder
Feeds raw bar stock into a spindle, relying on the dual adjustable air cushions to decelerate the 16 mm rod smoothly over the long 450 mm extension.
Woodworking Panel Stop
Acts as an adjustable end-stop for large wood panels on a sizing saw, using the built-in magnet to trigger a DMSG electronic sensor for precise cut indexing.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X450-10S the Right Cylinder?
Step down to the 32 mm bore (402 N push @0.5 MPa) for lighter loads, or up to the 50 mm bore (981 N push @0.5 MPa) if you need greater thrust. Choose this MBLCJ over an MBLJ when your moving mass requires adjustable end-of-stroke deceleration to protect the end covers, or over an MBLC if you need to fine-tune the travel endpoint.
The rear adjuster sets the travel stop, while the cushions manage deceleration—neither holds the load, so use an external lock for position holding. Mounting is limited to Basic, FA, or LB (no SDB or back-cover). Replacement match: 40 mm bore, 450 mm stroke, 10 mm adjust, G1/4 PT port, magnet included.
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 MBLCJ40X450-10S FAQ
At 0.5 MPa, this 40 mm bore cylinder provides 628 N push and 528 N pull force. At 0.7 MPa, push increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa.
The rear 10 mm stroke adjuster is a mechanical travel stop that sets your usable end position between 440-450 mm. The adjustable air cushion is a screw-tunable valve that controls end-of-stroke deceleration. Neither feature locks the load in place.
