About the Airtac MBLJ Adjustable Aluminum Alloy Mini Cylinder MBLJ25X160-30S
The AirTAC MBLJ25X160-30S is a double-acting, single-rod aluminum mini cylinder featuring a rear adjustable stroke. A built-in screw stopper lets you trim up to 30mm of travel, creating a usable end-position window from 130mm to 160mm. Delivering 245N push and 206N pull force at 0.5 MPa, it suits medium-duty positioning tasks. The -S code indicates a pre-fitted magnet for CMSG, DMSG, or EMSG sensor switches.
This compact riveted-barrel body uses a fixed rubber bumper to soften end impacts, meaning only the stroke length is adjustable, not the cushioning. The rear adjuster acts purely as a mechanical travel stop and will not hold a load without continuous air pressure. It carries a G1/8 port, a Ø10mm hard-chrome plated carbon steel rod, and a PT thread form.

The rear stopper sets the end position — it is a travel stop, not a lock. Overall length = A + 2 × stroke + adjustable stroke. MBLJ/MBLCJ mounting is Basic / FA / LB only (no SDB, no back-cover code). Thread options: PT / G / NPT.
Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 206 N |
| 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 MBLJ Adjustable Aluminum Alloy Mini Cylinder MBLJ25X160-30S Is Used
PCB Drill Bit Cassettes
Fine-tunes the push-out stroke (130-160mm window) for presenting 1.0mm drill bits to a pick-and-place head, using the 245N push force to overcome spring detents.
Bottle Filler Nozzles
Adjusts retraction on a 160mm stroke to set precise dip-tube depths for different PET bottle heights, preventing splash-back while using the DMSG sensor for fill counting.
Carton Flap Plows
Trims the end position by up to 30mm to tuck minor flaps on variable-width packaging cartons, ensuring the 206N pull force reliably clears the plow arm.
Is the Airtac MBLJ Adjustable Aluminum Alloy Mini Cylinder MBLJ25X160-30S the Right Cylinder?
Stepping down to the Ø20 bore yields 157N push force, whereas stepping up to the Ø32 bore provides 402N. Choose this 25mm bore when your mechanism requires around 245N of push force at 0.5 MPa. If your application needs adjustable pneumatic cushioning rather than just a stroke stop, select the MBLCJ variant; if you need a fixed length without the adjuster, choose the standard MBL. The rear stopper on this unit sets the end position but is not a locking brake. Mounting is limited to Basic, FA, or LB styles, as MBLJ excludes SDB pivot and back-cover options.
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 MBLJ Adjustable Aluminum Alloy Mini Cylinder MBLJ25X160-30S FAQ
At 0.5 MPa, it provides 245N push and 206N pull force. At 0.7 MPa, the push force is 343N. The maximum theoretical force is 50 kgf at 1.0 MPa.
The rear stopper allows you to trim the stroke end position by up to 30mm, giving a usable travel window of 130mm to 160mm. The adjuster is a travel stop, not a lock; it sets the end position but does not hold the load without live air pressure.
