About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X150-30
The AirTAC MBLCJ25X150-30 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 30 mm rear trimmer creates a usable travel window of 120 to 150 mm, ideal for dialing in exact end positions on a 25 mm bore frame. Tunable end-of-stroke cushioning absorbs kinetic energy faster than a fixed rubber bumper, protecting the end covers during rapid moves.
This SKU omits the -S magnet, meaning it cannot host a CMSG reed or DMSG electronic sensor for position feedback. The Ø10 mm carbon-steel rod features 20 um hard-chrome plating, and the riveted rolling-packed barrel pairs with a grease-retaining piston seal to minimize wear. Remember the rear stopper sets the travel end but does not lock the load, and the overall length equals A + 2 x stroke + adjust.

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)

| 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 MBLCJ Adjustable Mini Cylinder MBLCJ25X150-30 Is Used
PCB Router Z-Axis
Governs the plunge depth of a spindle on a desktop PCB router. The 120-150 mm travel window allows fine-tuning the cut depth into the copper-clad board, while the air cushion prevents spindle bounce at stroke end.
Bottle Capper Head
Drives a capping chuck onto plastic beverage bottles. The 245 N push force seats caps firmly, and the tunable cushioning decelerates the chuck to avoid shattering the plastic threads.
Textile Guide Needle
Actuates a weft guide needle on a narrow-loom weaving machine. The 150 mm stroke shifts the yarn across the warp shed, with the rear stopper locking the exact shed width without relying on pneumatic pressure.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X150-30 the Right Cylinder?
If 245 N at 0.5 MPa is too much force, step down to the 20 mm bore, which yields 157 N push and 132 N pull. If you need more thrust, step up to the 32 mm bore, providing 402 N push and 346 N pull at the same pressure. Choose this MBLCJ over the MBLJ when your moving mass requires tunable pneumatic deceleration rather than a fixed bumper, or over the MBLC if you need to trim the 150 mm stroke down to 120 mm. The rear adjuster is a travel stop, not a lock; the rod drifts without live air, so use an external lock for holding. Mounting is limited to Basic, FA, or LB; there is no SDB pivot or back-cover option. To replace this exact unit, match the 25 mm bore, 150 mm stroke, 30 mm adjust code, G1/8 PT port, 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 MBLCJ25X150-30 FAQ
At 0.5 MPa it provides 245 N push and 206 N pull force. At 0.7 MPa the push force is 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa.
This specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG position sensors. The 30 mm rear adjuster lets you trim the usable stroke down to 120 mm, but it is a mechanical travel stop, not a load lock. The adjustable air cushion only controls end-of-stroke deceleration.
