About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X350-75S
The AirTAC MBLCJ32X350-75S is a compact double-acting mini cylinder featuring a single Ø12mm carbon-steel rod and a riveted aluminum barrel. It delivers 402N of push force at 0.5MPa and integrates an adjustable rear stroke stopper, yielding a usable travel window of 275 to 350mm. A built-in magnet enables position detection, while screw-tunable air cushions at both ends absorb kinetic energy to prevent end-cover damage during fast 350mm extensions.
This model distinguishes its rear travel stopper from its end-of-stroke cushioning; the adjuster sets the end position but does not lock the load, and the cushion only decelerates. Because the 350mm stroke is substantial for a 32mm bore, the 12mm rod is susceptible to bending under lateral stress, making an external guide rail essential for stability. The grease-retaining two-way piston seal maintains consistent lubrication, and the overall length extends by the 75mm adjustment dimension.

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)
| Pressure | Push force | Pull force |
|---|---|---|
| 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 MBLCJ32X350-75S Is Used
PCB Router Z-Axis
Drives the plunge axis of a PCB depaneling router, using the 275-350mm stroke window to dial in cutting depth while the air cushions absorb spindle vibration at stroke ends.
Pallet Divert Arm
Actuates a diverting gate on a 50mm conveyor line, relying on the 402N push force to overcome friction and the adjustable cushion to prevent the arm from slamming into stops.
Vision System Ejector
Pushes failed vision-inspected parts out of a high-speed tray using the DMSG solid-state sensor to confirm full ejection at 350mm before the next cycle.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X350-75S the Right Cylinder?
When sizing this 32mm bore (402N push at 0.5MPa), step down to the 25mm bore for 245N push force if your load is lighter, or step up to the 40mm bore for 628N push force if you need greater thrust. Choose this MBLCJ over the MBLJ when your moving mass requires tunable pneumatic deceleration rather than a fixed rubber bumper, or over the MBLC if your machine design demands a variable end-position window. Neither the rear stopper nor the air cushion will mechanically hold a load in place without live air pressure; use an external locking mechanism for true position holding.
For replacements, match the 32mm bore, 350mm stroke, and 75mm adjust code exactly. This SKU uses a G1/8 port, a PT thread form, and a built-in magnet for CMSG, DMSG, or EMSG sensors. Mounting is limited to Basic, FA flange, or LB foot brackets; rear pivot or back-cover mounts are not supported on this series.
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 MBLCJ32X350-75S FAQ
This 32mm bore cylinder generates 402N push and 346N pull force at 0.5MPa, 563N push at 0.7MPa, and a maximum theoretical output of 82kgf at 1.0MPa. The 350mm stroke is within the 32-63mm bore group's 500mm maximum standard stroke limit.
The -S suffix indicates a built-in magnet for use with AirTAC CMSG reed switches or DMSG/EMSG electronic sensors for position detection. The 75mm rear adjuster allows you to trim the stroke down to a 275mm minimum, but it acts only as a travel stop and does not lock the load; the adjustable air cushion independently handles end-of-stroke deceleration.
