About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X175-30
The AirTAC MBLCJ32X175-30 is a compact double-acting aluminum mini cylinder featuring a rear travel stopper and tunable end-of-stroke cushioning. The 30 mm adjuster trims the return path, creating a usable extension window of 145-175 mm. Delivering 402 N of push force at 0.5 MPa, it is built for mid-range actuation where a fixed bumper would fail. The riveted rolling-packed barrel and grease-retaining piston seal ensure consistent friction across the 175 mm travel.
Unlike the base MBLJ which relies on a fixed rubber bumper, this MBLCJ variant incorporates a screw-tunable ADJUSTABLE AIR CUSHION at both ends to decelerate heavier loads smoothly. The rear stopper sets the end position but does not hold the load; external guides are recommended for this 175 mm stroke to prevent rod side-loading. Note that because this specific SKU lacks the -S suffix, it has no built-in magnet and cannot support CMSG or DMSG position sensors.

| 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 MBLCJ32X175-30 Is Used
PCB Router Z-Axis
Lifts and lowers a spindle router on printed circuit boards. The 402 N push handles the tool weight, while the 145-175 mm stroke window allows precise depth trimming without changing machine stops.
Textile Loom Tensioner
Feeds a fabric tensioning arm on an industrial weaving machine. The adjustable air cushion prevents the 175 mm stroke from snapping the arm violently at the end of each cycle, protecting the yarn.
Carton Flap Folder
Actuates a folding mechanism on a packaging line. The 346 N pull force neatly tucks heavy cardboard flaps, and the rear stopper allows operators to fine-tune the fold depth by up to 30 mm.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X175-30 the Right Cylinder?
Stepping down, the 25 mm bore provides 245 N push at 0.5 MPa, while stepping up to the 40 mm bore yields 628 N—choose the 32 mm for applications needing around 400 N without excess bulk. Select this MBLCJ over the MBLJ when your moving mass requires tunable pneumatic deceleration rather than a hard rubber impact. Remember that the adjustment screw is a travel stop, not a mechanical lock; the air cushion only decelerates, so a separate locking device is required to hold position against external forces.
Mounting is restricted to Basic, FA flange, or LB foot styles, as the MBLCJ series omits the back-cover and SDB pivot options found on other types. The overall length extends by the 30 mm adjuster on top of the standard stroke. To replace this unit, match the 32 mm bore, 175 mm stroke, 30 mm adjust code, G1/8 port, M10x1.25 rod thread, PT thread form, and confirm no magnet is required.
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 MBLCJ32X175-30 FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 346 N of pull force. At 0.7 MPa, the push force increases to 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa.
No, this specific SKU lacks the -S suffix, meaning it has no internal magnet and cannot accept CMSG or DMSG electronic position switches. The adjustable air cushion is a screw-tunable valve at both ends that restricts exhaust air to decelerate the piston near the stroke ends; it is not a lock and does not hold the load.
