About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X160-40
The AirTAC MBLCJ25X160-40 is a compact double-acting aluminum mini cylinder featuring a rear travel adjuster and an adjustable air cushion at both ends. The 40 mm adjuster trims the rear stroke, yielding a usable travel window of 120 to 160 mm. Delivering 245 N of push force at 0.5 MPa, this 25 mm bore unit suits mid-distance positioning tasks that need precise end-of-stroke tuning.
Unlike the fixed rubber bumper on an MBLJ, the screw-tunable air cushion here decelerates heavier loads at high speeds to protect the end covers. The rear stopper sets the travel end but does not lock the load, while the riveted rolling-packed barrel and 20 um hard-chrome plated carbon-steel rod ensure durable service. This specific SKU lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensors.

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 MBLCJ25X160-40 Is Used
PCB Conveyor Gating
Cycles a 160 mm gate arm to route printed circuit boards on a production line, using the 245 N push force and tuned cushion to prevent shock on the aluminum profiles.
Dispenser Head Positioning
Moves a fluid dispensing nozzle across a 120-160 mm window, relying on the rear stopper to set the exact dispense location without needing a mechanical lock.
Light-Part Ejection
Pushes molded plastic parts out of a machining center, using the adjustable air cushion to soften the end-of-stroke impact during rapid 800 mm/s ejection.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X160-40 the Right Cylinder?
Stepping down to the 20 mm bore drops the output to 157 N push at 0.5 MPa, whereas moving up to the 32 mm bore increases it to 402 N. Choose this MBLCJ over the MBLJ when your 160 mm move carries enough mass to require tunable pneumatic deceleration rather than a fixed rubber bumper. The rear adjuster sets a hard stop, and the cushion controls deceleration, but neither will hold a load in place without live air pressure.
Mounting is limited to Basic, FA flange, or LB foot styles, as there is no back-cover or SDB pivot option for this series. The G1/8 port and M10x1.25 rod-end thread are standard for this 25 mm bore. For an exact replacement, match the 25 mm bore, 160 mm stroke, 40 mm adjust code, 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 MBLCJ25X160-40 FAQ
At 0.5 MPa it provides 245 N push and 206 N pull. At 0.7 MPa the push increases to 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa.
The 40 mm rear adjuster acts as a travel stop, letting you set the effective stroke anywhere between 120 and 160 mm. It is not a lock or brake; the adjustable air cushion only controls deceleration, so an external device is needed to hold position without air.
