About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X100-30
The AirTAC MBLCJ25X100-30 is a compact double-acting mini cylinder featuring a rear stroke adjuster and tunable air cushions at both ends. It delivers 245 N of push force at 0.5 MPa. The rear stopper trims up to 30 mm of travel, creating a usable stroke window of 70 to 100 mm. This specific travel range is ideal for precise component insertion or varying depth requirements. A standard PT thread G1/8 port and an M10x1.25 rod end are specified for this 25 mm bore.
Unlike the standard MBLJ bumper, the adjustable air cushion here allows screw-tuning of end-of-stroke deceleration to handle faster cycling without slamming the covers. The riveted aluminum barrel and grease-retaining piston seal keep the bore compact for tight machine spaces. This SKU lacks a built-in magnet, meaning it cannot support CMSG or DMSG position sensors. The rear adjuster acts purely as a mechanical travel stop and does not lock the load in place.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X100-30 Is Used
PCB Depaneling Saw Feed
Uses the 70-100 mm stroke window to feed a depaneling blade through varying board widths, relying on the 245 N push force and tuned cushion to prevent bounce at stroke end.
Dispenser Valve Actuation
Adjusts the rear stopper to set exact shot volumes for an adhesive dispenser, while the tunable air cushion protects the valve seat from impact during high-speed retraction.
Textile Loom Takedown
Drives a fabric takedown mechanism with a 100 mm stroke, where the 25 mm bore provides sufficient pull force and the cushion absorbs the kinetic energy of the rod.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X100-30 the Right Cylinder?
If you need less force, step down to the 20 mm bore (157 N push at 0.5 MPa); if your payload requires more thrust, step up to the 32 mm bore (402 N push at 0.5 MPa). Choose this MBLCJ over the MBLJ when your cycle speed demands tunable end-cushioning rather than a fixed rubber bumper, or over the MBLC if you need to trim the travel end. Remember that the rear adjuster sets the stroke end while the cushion decelerates the piston—neither holds the load, so use an external lock for position holding. Mounting is limited to Basic, FA, or LB; no SDB pivot or back-cover options exist. To replace this cylinder, match the 25 mm bore, 100 mm stroke, 30 mm adjust code, G1/8 PT port, and lack of a 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 MBLCJ25X100-30 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 is 343 N, with a maximum theoretical output of 50 kgf at 1.0 MPa. The air supply port is G1/8 with a standard PT thread.
The rear adjuster lets you trim up to 30 mm of travel, creating a usable stroke window of 70 to 100 mm. This stopper sets the end position but does not lock the load. Additionally, this specific SKU lacks a built-in magnet, so it cannot accept CMSG or DMSG position sensors.
