About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X160-40S
The AirTAC MBLCJ25X160-40S is a compact double-acting mini cylinder with a 25mm bore and a 160mm stroke. It features a rear adjustable stroke stopper allowing you to trim up to 40mm of travel, creating a usable end-position window of 120 to 160mm. Driven by air on both sides of the piston, it generates 245N of push force and 206N of pull force at 0.5MPa. This specific SKU includes a built-in magnet (-S) for use with CMSG reed and DMSG or EMSG electronic sensor switches to track rod position.
Unlike the base MBLJ which relies on a fixed rubber bumper, this model features an adjustable air cushion at both ends. You can screw-tune the end-of-stroke deceleration to handle faster cycling or heavier moving masses without slamming the end covers. The riveted rolling-packed aluminum barrel keeps the body light for tight spaces, while the 10mm carbon-steel rod features 20μm hard-chrome plating to resist wear. The rear adjuster sets the travel end-point but does not mechanically lock or hold the load in place.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X160-40S Is Used
PCB Router Z-Axis
Deploys a routing spindle across a 120-160mm travel window. The tuned air cushion prevents bit chatter on rapid plunge exits, while the 245N push force handles light spindle weight.
Textile Tensioning Arm
Feeds fabric web into a sewing head. The rear stroke stopper dials the exact material slack, and the cushion decelerates the 160mm extension to protect yarn from snapping.
Carton Flap Folder
Pushes corrugated cardboard flaps at high speed on a packaging line. The -S magnet triggers a DMSG electronic switch to confirm flap position before the sealer.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X160-40S the Right Cylinder?
Choose this 25mm bore if your application requires roughly 245N (25kgf) of push force at 0.5MPa. If you need less force, step down to the 20mm bore which provides 157N of push force. If your payload is heavier, step up to the 32mm bore which yields 402N. The 160mm stroke suits mechanisms needing extended reach, but remember that the 10mm rod is susceptible to bending under lateral stress—always use an external guide rail for long strokes to prevent side-load damage.
When replacing this unit, match the 25mm bore, 160mm stroke, 40mm adjust code, G1/8 port, PT thread form, and the -S magnet. The adjustable air cushion helps absorb kinetic energy at the stroke ends, but neither the cushion nor the rear stroke adjuster acts as a brake or load-holding device; you must use external mechanics to hold position. Mounting is limited to Basic, FA flange, or LB foot options, as there is no SDB pivot or back-cover configuration available for the MBLCJ series.
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 MBLCJ25X160-40S FAQ
At 0.5MPa, it provides 245N push and 206N pull force. At 0.7MPa, push increases to 343N. The maximum operating pressure is 1.0MPa, yielding a theoretical max of 50kgf.
The rear adjuster trims up to 40mm of travel, giving a usable stroke window of 120-160mm. It functions only as a travel stop to set the end position; it does not lock or hold the load pneumatically. The separate adjustable air cushion only controls end-of-stroke deceleration.
