About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X400-75
The AirTAC MBLCJ32X400-75 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. It delivers 402 N of push force at 0.5 MPa via a Ø12 mm carbon-steel rod. The 75 mm rear trimmer creates a usable travel window of 325 to 400 mm, ideal for dialing in exact end positions on longer 400 mm strokes.
Unlike the fixed rubber bumper on an MBLJ, the screw-tunable air cushion here decelerates heavier loads near stroke ends to protect the end covers. The rear stopper sets the travel limit but does not lock the load; an external guide is required for this 400 mm stroke to prevent rod bending. This SKU lacks a built-in magnet, so it cannot accept CMSG, DMSG, or EMSG position sensors.

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 (Ø32mm)

|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 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 MBLCJ32X400-75 Is Used
Textile Loom Weft Insertion
Uses the 325-400 mm adjustable travel window to precisely set the insertion distance for varying fabric widths, relying on the 402 N push force to drive the guide mechanism.
Packaging Carton Flap Folding
Tunes the adjustable air cushion to smoothly decelerate the 400 mm stroke when folding heavy cardboard, preventing impact damage to the cylinder end covers.
Bottling Line Diverting
Pushes glass containers between lanes using the 346 N pull force, with the rear stopper locking the travel at exactly 380 mm to match the conveyor spacing.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X400-75 the Right Cylinder?
Step down to the 25 mm bore (245 N push @0.5 MPa) for lighter loads, or step up to the 40 mm bore (628 N push @0.5 MPa) if you need more thrust. Choose this MBLCJ over an MBLJ when your moving mass requires tunable end-of-stroke deceleration instead of a fixed bumper, or over an MBLC if you need to fine-tune the travel end.
The exact replacement match is a 32 mm bore, 400 mm stroke, 75 mm adjust code, G1/8 port, PT thread, Basic mounting, with no magnet. The rear adjuster is a travel stop, not a lock, and the cushion only decelerates; neither holds position without live air. Mounting is limited to Basic, FA, or LB (no SDB or back-cover). Because the stroke is 400 mm, an external guide is mandatory to prevent side-load damage to the 12 mm rod.
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 MBLCJ32X400-75 FAQ
At 0.5 MPa, the push force is 402 N and the pull force is 346 N. At 0.7 MPa, the push force is 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa.
This SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG position sensors. The 75 mm rear adjuster is a travel stop that sets the 325-400 mm window, and the air cushion handles deceleration; neither acts as a lock to hold the load without live air.
