About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X30-10S
The AirTAC MBLCJ25X30-10S is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. It delivers 245 N of push force and 206 N of pull force at 0.5 MPa. The integrated magnet (-S) enables precise rod position detection using AirTAC CMSG, DMSG, or EMSG sensor switches.
This model features a 30 mm nominal stroke with a 10 mm rear adjustment, creating a usable travel window of 20 to 30 mm. The screw-tunable air cushions allow you to dial in end-of-stroke deceleration for faster cycling speeds while protecting the end covers. Note that the rear stopper simply sets the travel end and the cushion only decelerates; neither component mechanically locks the load in place.

| 0.7 MPa | 344 N | — |
| Max (@1.0 MPa) | 50 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 MBLCJ25X30-10S Is Used
PCB Edge Routing Dampening
Uses the 20-30 mm adjustable stroke window and tunable air cushion to smoothly decelerate a 245 N routing head, preventing chatter during printed circuit board depaneling.
Micro-Dispenser Needle Seating
Leverages the magnetic piston for position feedback and the adjustable end cushion to softly seat a dispensing needle without damaging delicate fluid nozzles.
Lightweight Film Web Steering
Employs the 30 mm stroke and 10 mm rear stopper trim to precisely tension and steer packaging film webs, relying on the 206 N pull force for stable tracking.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X30-10S the Right Cylinder?
Choose this 25 mm bore when you need 245 N of thrust at 0.5 MPa within a tight footprint. If your application requires less force, stepping down to the 20 mm bore yields 157 N of push force. If you need more power, stepping up to the 32 mm bore provides 402 N. Select the MBLCJ over the MBLJ when your dynamic loads demand tunable pneumatic damping rather than a fixed rubber bumper, or choose the MBLC variant if you do not need rear stroke trimming.
For exact replacements, match the 25 mm bore, 30 mm stroke, 10 mm adjust code, G1/8 port, M10x1.25 rod thread, PT thread form, and the -S magnet. Mounting is limited to Basic, FA flange, or LB foot styles; no back-cover or SDB pivot options exist. The riveted rolling-packed barrel and 20 µm hard-chrome plated carbon-steel rod ensure durable, low-friction operation across the 30 to 800 mm/s speed range.
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 MBLCJ25X30-10S 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.
The 10 mm adjustable stroke is a mechanical rear stopper that limits travel to a 20-30 mm window. The adjustable air cushion is a needle valve that controls exhaust flow to decelerate the piston near the end caps. Neither feature locks the load; external holding mechanisms are required for position retention without air pressure.
