About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X125-75
The AirTAC MBLCJ25X125-75 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and a tunable air cushion at both ends. It delivers 245 N of push force and 206 N of pull force at 0.5 MPa. The rear stopper allows you to trim up to 75 mm of travel, creating a usable stroke window of 50 to 125 mm for precise end-positioning. Equipped with a G1/8 port and an Ø10 rod, this configuration uses a standard PT thread and ships without a built-in magnet.
Unlike the base MBLJ which relies on a fixed rubber bumper, this model uses screw-tunable end-of-stroke deceleration to absorb kinetic energy, protecting the end covers during faster or heavier moves. The riveted rolling-packed barrel and heterogeneous two-way grease-retaining piston seal minimize wear, while the carbon-steel rod features 20 µm hard-chrome plating for corrosion resistance. Note that the rear adjuster acts purely as a mechanical travel stop and does not lock or hold the load in place.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X125-75 Is Used
Packaging Conveyor Diverter
Provides 245 N of push force to deflect cardboard cartons on a packaging line, using the 50-125 mm stroke window to time the diverting stroke perfectly.
PCB Router Gate
Tunes the air cushion to softly decelerate a routing gate handling delicate printed circuit boards, preventing impact damage at the end of travel.
Textile Tensioning Arm
Uses the 75 mm rear stroke adjustment to fine-tune the resting position of a fabric tensioning arm, maintaining exact material feed without needing a sensor.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X125-75 the Right Cylinder?
If you need less force, the neighbouring 20 mm bore provides 157 N of push at 0.5 MPa, whereas stepping up to the 32 mm bore yields 402 N. Choose this MBLCJ over the MBLJ when your application demands tunable end-of-stroke deceleration rather than a fixed bumper, or over the MBLC when you need that rear travel-stop adjustment. Remember that neither the cushion nor the adjuster acts as a lock; the rod will drift without live air, so use an external guide for side-load support. Mounting is limited to Basic, FA, or LB styles (no SDB or back-cover options). For a direct replacement, match the 25 mm bore, 125 mm stroke, 75 mm adjust code, G1/8 port, PT thread, and confirm no magnet is fitted.
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 MBLCJ25X125-75 FAQ
At 0.5 MPa, this 25 mm bore cylinder provides 245 N of push force and 206 N of pull force. At 0.7 MPa, the push force increases to 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa.
No, this specific SKU lacks the built-in -S magnet, meaning it cannot accept AirTAC CMSG, DMSG, or EMSG position switches. Additionally, the 75 mm rear adjuster only sets the travel end-point; it is a mechanical stop, not a lock, and the rod will drift without live air pressure.
