About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X160-30S
The AirTAC MBLCJ25X160-30S is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and a tunable air cushion at both ends. It delivers 245 N of push force and 206 N of pull force at 0.5 MPa. The built-in magnet enables position detection. You can trim up to 30 mm of travel at the rear, creating a usable stroke window of 130 to 160 mm. This makes it highly effective for applications requiring exact end-position tuning without swapping hardware.
Unlike the fixed rubber bumper on an MBLJ, the adjustable air cushion on this SKU allows you to screw-tune the end-of-stroke deceleration, absorbing kinetic energy to protect the end covers during faster or heavier moves. The riveted rolling-packed aluminum barrel and two-way grease-retaining piston seal maintain internal lubrication over high cycle counts. The Ø10 mm carbon-steel rod features 20 µm hard-chrome plating to resist corrosion and scoring in demanding industrial environments.

| 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 MBLCJ25X160-30S Is Used
PCB Router Z-Axis
Drives the vertical plunge of a compact PCB depaneling router, using the 130-160 mm adjustable window to set exact cutting depth while the air cushion prevents jarring stops.
Dispenser Valve Actuation
Actuates a pneumatic glue dispenser, relying on the 245 N push force to open high-viscosity valves and the DMSG electronic sensor to trigger the dosing timer.
Small Parts Ejection
Ejects stamped metal clips from a die set, using the 160 mm stroke to clear the tooling area while the cushion absorbs the kinetic energy of the 10 mm rod at speed.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X160-30S the Right Cylinder?
With a 245 N push force at 0.5 MPa, this 25 mm bore fits medium-duty compact tasks. If you need less force, step down to the 20 mm bore (157 N push); if your payload is heavier, step up to the 32 mm bore (402 N push). Choose this MBLCJ over the MBLJ when your dynamics require tunable deceleration rather than a fixed bumper, or over the MBLC when you need the rear travel stopper to fine-tune the 130-160 mm end position.
Remember that the rear stopper is a travel stop, not a lock; it sets the end position but cannot hold a load against drift, and the cushion only decelerates. Mounting is limited to Basic, FA (flange), or LB (foot) brackets, as this series omits SDB pivot and back-cover options. To replace this unit, match the 25 mm bore, 160 mm stroke, 30 mm adjust code, G1/8 port, PT thread, and the -S magnet. Because the stroke is 160 mm, the 10 mm rod is susceptible to bending under heavy side-loads, so an external guide rail is recommended to prevent premature seal wear.
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 MBLCJ25X160-30S 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 rear adjuster is a mechanical travel stop that lets you trim the usable stroke window down to 130 mm from the 160 mm maximum. The adjustable air cushion is a separate screw-tunable feature that controls end-of-stroke deceleration. Neither feature locks or holds the load in place; you need live air pressure or an external lock for holding.
