About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X160-20
The AirTAC MBLCJ25X160-20 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and tunable air cushions at both ends. The 20 mm rear stopper yields a usable travel window of 140-160 mm. Delivering 245 N of push force at 0.5 MPa, it suits mid-distance positioning tasks. The riveted rolling-packed barrel and hard-chrome plated carbon-steel rod ensure durability in tight spaces.
Unlike the fixed rubber bumper on an MBLJ, the screw-tunable end cushions here decelerate heavier loads at high speeds, protecting the end covers. The rear adjuster acts strictly as a travel stop and does not lock the load. Because this specific SKU lacks the -S suffix, it has no built-in magnet and cannot support CMSG, DMSG, or EMSG position sensors.

| Series | MBL aluminum-barrel mini round cylinder (adjustable stroke) |
| Bore size | Ø25 mm |
| Nominal stroke | 160 mm |
| Adjustable window | 140–160 mm (trim 20 mm) |
| Acting type | Double acting |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|

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 MBLCJ25X160-20 Is Used
PCB Drill Bit Loader
Uses the 140-160 mm adjustable stroke window to precisely seat fragile drill bits into collets, relying on the 245 N push force without over-traveling.
Lightweight Parts Sorter
Leverages the dual adjustable air cushions to softly decelerate the 160 mm stroke when rapidly diverting small plastic components into packaging bins.
Label Applicator Tamp
Provides consistent 206 N pull force to retract a labeling head from a moving web, with the rear stopper ensuring exact label placement depth.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X160-20 the Right Cylinder?
For lower force needs, stepping down to the Ø20 bore provides 157 N push at 0.5 MPa, while stepping up to the Ø32 bore yields 402 N for heavier payloads. Choose this MBLCJ over the MBLJ when your 160 mm move requires adjustable end-of-stroke deceleration rather than a fixed bumper, or over the MBLC if you need the 140-160 mm rear travel trim. Note that the adjuster and cushions are not locks; external guides are needed for side-load stability on long strokes.
Mounting is limited to Basic, FA (flange), or LB (foot) styles, as no back-cover or SDB pivot options exist for this series. The exact replacement match requires a 25 mm bore, 160 mm stroke, 20 mm adjust code, G1/8 port, PT thread, and no magnet. Overall length equals A + 2 x stroke + adjust.
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 MBLCJ25X160-20 FAQ
This 25 mm bore cylinder uses a G1/8 port and delivers 245 N push / 206 N pull at 0.5 MPa, 343 N push at 0.7 MPa, and a maximum theoretical 50 kgf at 1.0 MPa.
No, this SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG sensors. The 20 mm rear adjuster is a travel stop, not a lock; the air cushion only tunes deceleration, so neither holds position without live air.
