About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X160-30
The AirTAC MBLCJ25X160-30 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 rear stopper allows you to trim up to 30 mm of travel, creating a usable stroke window of 130 to 160 mm for exact endpoint positioning. Because this SKU lacks the -S magnet code, it cannot accept a CMSG, DMSG, or EMSG position sensor.
Unlike the standard MBLJ which relies on a fixed rubber bumper, this model uses screw-tunable end-of-stroke cushioning to decelerate faster or heavier loads smoothly, protecting the end covers. The 10 mm carbon-steel rod features 20 um hard-chrome plating to resist wear, while the heterogeneous two-way grease-retaining piston seal maintains lubrication. Remember that the rear adjuster is a travel stop, not a mechanical lock; it sets the end position but does not hold the load in place without live air pressure.

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 MBLCJ25X160-30 Is Used
PCB Router Z-Axis
Drives a light spindle carriage across the 130-160 mm window, using the tunable air cushion to soften the rapid 245 N descent at the stroke bottom.
Dispenser Head Trim
Adjusts the rear stopper on a fluid dispensing nozzle to hit varying container heights, preventing hard impacts that could crack the end covers.
Small Part Ejector
Pushes molded plastic parts out of a press, relying on the 206 N pull force to retract the 10 mm rod quickly without bottoming out harshly.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X160-30 the Right Cylinder?
If you need less force, stepping down to the 20 mm bore yields 157 N of push force at 0.5 MPa, whereas stepping up to the 32 mm bore provides 402 N. Choose this MBLCJ over the MBLJ when your application's speed or mass requires tunable deceleration rather than a fixed bumper, or over the MBLC when you need to fine-tune the rear travel endpoint. The rear adjuster and the air cushion regulate movement and deceleration, but neither acts as a locking mechanism—use an external guide or lock for holding loads. Mounting is limited to Basic, FA flange, or LB foot brackets, as there is no back-cover or SDB pivot option. To replace this cylinder exactly, match the 25 mm bore, 160 mm stroke, 30 mm adjust code, G1/8 port, PT thread, and confirm no magnet is required.
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 MBLCJ25X160-30 FAQ
This 25 mm bore cylinder delivers 245 N push and 206 N pull at 0.5 MPa, 343 N push at 0.7 MPa, and a maximum theoretical 50 kgf at 1.0 MPa. It uses a G1/8 port, a Ø10 mm rod with an M10x1.25 rod-end thread, and operates at 30-800 mm/s.
The 30 mm rear stroke adjustment is a mechanical travel stop that sets your usable endpoint window between 130 and 160 mm. The adjustable air cushion is a separate screw-tunable valve that controls end-of-stroke deceleration. Neither holds the load without air pressure.
