About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X175-75S
The AirTAC MBLCJ25X175-75S is a compact double-acting mini cylinder featuring a single rod and a lightweight riveted aluminum barrel. It integrates a rear stroke adjuster allowing you to trim up to 75 mm of travel, creating a usable end-position window of 100-175 mm. Delivering 245 N of push force at 0.5 MPa, this 25 mm bore unit is paired with tunable air cushions at both ends to optimize deceleration.
Equipped with a built-in magnet (-S), it supports CMSG reed and DMSG or EMSG solid-state sensor switches for precise position detection. The 20 µm hard-chrome plated carbon-steel rod resists wear, while the heterogeneous two-way grease-retaining piston seal maintains lubrication. Remember that the rear adjuster acts purely as a mechanical travel stop, not a load-holding lock.

| Series | MBL aluminum-barrel mini round cylinder (adjustable stroke) |
| Bore size | Ø25 mm |
| Nominal stroke | 175 mm |
| Adjustable window | 100–175 mm (trim 75 mm) |
| Acting type | Double acting |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |

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 MBLCJ25X175-75S Is Used
Packaging Carton Flap
Handles 245 N push to fold heavy cardboard flaps on a continuous packaging line, using the 75 mm rear stroke adjustment to fine-tune the 175 mm travel window for varying box sizes.
Textile Loom Takedown
Provides steady pulling force (206 N at 0.5 MPa) to guide woven fabric, relying on the adjustable air cushion to prevent sudden jerks that would tear delicate threads at high speed.
PCB Router Pin Lift
Lifts a routing fixture in an electronics assembly machine, using the DMSG electronic sensor to confirm the 100 mm retracted position before the cutting spindle descends.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X175-75S 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 thrust to 402 N. Choose this MBLCJ over the MBLJ when your application requires screw-tunable end-of-stroke deceleration instead of a fixed rubber bumper, or over the MBLC if you need rear travel trimming. Neither the cushion needle nor the rear stopper will hold a load in place without continuous air pressure. Mounting is restricted to Basic, FA flange, or LB foot brackets (no SDB or back-cover options). For an exact replacement, match the 25 mm bore, 175 mm stroke, 75 mm adjust, G1/8 port, PT thread, and the -S magnet.
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 MBLCJ25X175-75S FAQ
At 0.5 MPa it provides 245 N push and 206 N pull force. At 0.7 MPa the push increases to 343 N, and the maximum theoretical force is 50 kgf at 1.0 MPa.
The 75 mm rear adjuster mechanically trims the travel window down to 100 mm, acting as a hard stop. The adjustable air cushion only regulates shock deceleration near the end covers; neither mechanism locks or holds the load without air pressure.
