About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X125-75
The AirTAC MBLCJ32X125-75 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and tunable air cushioning at both ends. It delivers 402 N of push force at 0.5 MPa through a 32 mm bore. The rear adjuster trims up to 75 mm of travel, yielding a usable stroke window of 50 to 125 mm, making it highly versatile for varying machine spacing requirements. The 125 mm stroke falls well within the 500 mm maximum standard for this bore size.
This model uses a G1/8 port and a 12 mm carbon-steel rod with 20 um hard-chrome plating to resist wear. Distinguishing the two adjustment mechanisms is key: the rear stopper sets the travel end position, while the separate needle valves tune end-of-stroke deceleration to absorb kinetic energy and protect the end covers. Because this specific SKU lacks the -S magnet code, it cannot accept a CMSG, DMSG, or EMSG position sensor switch.

| 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 MBLCJ32X125-75 Is Used
PCB Router Z-Axis
Governs the plunge depth of a spindle motor on a printed circuit board routing machine, using the 50-125 mm window to dial in exact depth limits while the cushion prevents snap-back at the top of the cycle.
Label Applicator Tamp
Drives a tamp pad to press adhesive labels onto cartons, relying on the 402 N push force to ensure firm adhesion while the adjustable cushion decelerates the pad to avoid crushing the packaging.
Textile Guide Bar
Positions a yarn guide bar across a weaving loom, where the 125 mm travel shifts the thread alignment and the rear stopper allows rapid 75 mm shortening for pattern changes without changing hardware.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X125-75 the Right Cylinder?
Stepping down to the 25 mm bore yields 245 N push at 0.5 MPa, while moving up to the 40 mm bore provides 628 N if your payload requires more force. Choose this MBLCJ over the MBLJ variant when your application moves heavier masses at higher speeds and needs screw-tunable deceleration rather than a fixed rubber bumper. Compared to the MBLC, this model adds the rear travel stopper for variable positioning.
Remember that neither the rear travel stopper nor the cushion needle holds the load pneumatically; the rod will drift without live air pressure, so use an external locking device for static holding. Mounting is restricted to Basic, FA flange, or LB foot styles; there is no SDB pivot or back-cover option. The overall length extends to A plus 2 times stroke plus the 75 mm adjuster. For exact replacement matching, verify bore 32, stroke 125, adjust 75, port G1/8, PT thread, and no magnet.
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 MBLCJ32X125-75 FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N push and 346 N pull force. At 0.7 MPa, push increases to 563 N, with a theoretical maximum of 82 kgf at 1.0 MPa. The 125 mm stroke is standard, as the 32 mm bore supports up to 500 mm.
No, this specific SKU lacks the -S code, so it has no built-in magnet and cannot accept CMSG, DMSG, or EMSG switches. The 75 mm rear adjuster is a mechanical travel stop that sets your usable stroke window from 50 to 125 mm; it is not a lock, and the separate air cushion only regulates end-of-stroke deceleration.
