About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X450-100S
The AirTAC MBLCJ40X450-100S 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 push and 528 N pull force at 0.5 MPa. The 100 mm rear adjustment yields a usable travel window of 350 to 450 mm, allowing precise end-position tuning for varied automated equipment strokes.
Unlike the fixed rubber bumper on an MBLJ, the screw-tunable end cushions actively decelerate heavy 450 mm traverses, protecting the end covers. The riveted rolling-packed barrel and 20 um hard-chrome plated Ø16 carbon-steel rod ensure durability. The built-in magnet (-S) supports CMSG reed and DMSG/EMSG electronic sensors for position detection. At 450 mm, the side-load risk on the 16 mm rod is high, so external guiding rails are strongly advised.

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 MBLCJ40X450-100S Is Used
Injection Mold Ejection
Drives long-stroke ejector pins on a 450 mm cycle. The 628 N force reliably strips parts, while the 100 mm rear adjuster fine-tunes the ejection endpoint to match varying mold depths.
Packaging Conveyor Diverter
Sorts heavy cartons by extending a diverter arm. The adjustable air cushions absorb the kinetic energy of the 450 mm rapid traverse, preventing end-cover damage without slowing cycle times.
Textile Loom Beam Indexing
Shifts heavy warp beams into position. The DMSG electronic sensor tracks the full extension, while the 350-450 mm usable window allows operators to dial in the exact indexing pitch on the fly.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X450-100S the Right Cylinder?
Step down to a 32 mm bore for lighter loads (402 N push @0.5 MPa) or step up to a 50 mm bore for heavier thrust (981 N push @0.5 MPa). Choose MBLCJ over the MBLJ when your moving mass requires tunable pneumatic deceleration rather than a fixed bumper impact, or over the MBLC when you need that 350-450 mm adjustable end-point window. The rear stopper sets the travel end and the cushion regulates speed; neither component mechanically locks or holds the load in place without live air pressure.
Mounting is restricted to Basic, FA flange, or LB foot styles; no SDB pivot or back-cover options exist for this series. The exact replacement match requires a 40 mm bore, 450 mm stroke, 100 mm adjust code, G1/4 port, PT thread, and the -S magnet. Because the stroke is 450 mm, always pair this cylinder with an external linear guide to prevent rod bending under offset loads.
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 MBLCJ40X450-100S FAQ
At 0.5 MPa it provides 628 N push and 528 N pull. At 0.7 MPa the push increases to 880 N. The maximum theoretical force is 128 kgf at the 1.0 MPa operating pressure limit.
The 100 mm rear adjuster is a mechanical travel stop that sets your usable extension window between 350 and 450 mm. The adjustable air cushion is a separate needle valve that regulates pneumatic deceleration at the stroke ends. Neither feature locks the load; the cylinder drifts without live air.
