About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X150-10
The AirTAC MBLCJ25X150-10 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and tunable air cushions at both ends. It delivers 245 N push and 206 N pull force at 0.5 MPa. The 10 mm rear adjuster sets a usable travel window of 140-150 mm, allowing you to fine-tune the end position without mechanical spacers. Unlike the fixed rubber bumper on an MBLJ, the screw-tunable cushion valves let you dial in end-of-stroke deceleration for heavier or faster moving loads.
This 25 mm bore uses a G1/8 port and a Ø10 mm hard-chrome plated carbon steel rod with an M10x1.25 end thread. Because this specific SKU lacks the built-in magnet (-S), it cannot accept AirTAC CMSG, DMSG, or EMSG position sensors. The riveted rolling-packed barrel and grease-retaining piston seal ensure stable low-friction operation across the 30-800 mm/s speed range. Remember that the rear stopper sets the travel limit but does not lock the load in place; external holding mechanics are required if the air supply drops.

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 MBLCJ Adjustable Mini Cylinder MBLCJ25X150-10 Is Used
PCB Router Head Descent
Uses the 140-150 mm stroke window to precisely set the Z-axis cutting depth of a spindle motor, relying on the 245 N push force to plunge through fiberglass while the adjustable cushion prevents end-cover impact.
Label Applicator Tamp Stroke
Pneumatically extends a tamp pad to press adhesive labels onto cartons, using the 10 mm rear stroke adjustment to dial in exact label contact depth without reprogramming the machine controller.
Textile Loom Beam Indexing
Drives a indexing pawl in a weaving machine, using the 206 N pull force to retract the mechanism while the tunable air cushion absorbs the kinetic energy of the 150 mm rapid stroke.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X150-10 the Right Cylinder?
Choose this 25 mm bore when you need 245 N of thrust at 0.5 MPa. If your application requires less force, step down to the 20 mm bore (157 N push); if you need more clamping power, step up to the 32 mm bore (402 N push). This model is specified with standard PT tapered port threads and no magnet. When ordering a replacement, match the 25 mm bore, 150 mm stroke, 10 mm adjuster code, G1/8 port, M10x1.25 rod thread, and Basic mounting style (FA flange or LB foot are also available, but SDB pivot and back-cover options are not supported on the MBLCJ series).
At a 150 mm stroke, the Ø10 mm rod is subject to bending moments under high side loads. Use an external guide rail to prevent rod damage and premature seal wear. Distinguish the adjustable stroke (a mechanical travel stop) from the adjustable air cushion (end-of-stroke deceleration); neither mechanism will hold a load statically without continuous air pressure.
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 MBLCJ25X150-10 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.
No, this specific SKU does not have a built-in magnet (indicated by the lack of an 'S' in the model code), meaning it cannot accept AirTAC CMSG, DMSG, or EMSG position switches. Additionally, the 10 mm rear adjuster is a travel stop, not a lock; it sets a 140-150 mm usable stroke window but will not hold the load without air pressure.
