About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X150-50
The AirTAC MBLCJ25X150-50 is a compact double-acting mini cylinder featuring a riveted aluminum barrel and a single Ø10 mm carbon-steel rod with 20 μm hard-chrome plating. It delivers 245 N push and 206 N pull at 0.5 MPa. A rear stroke adjuster allows you to trim up to 50 mm of travel, creating a usable end-position window from 100 to 150 mm for precise machinery timing.
Unlike the base MBLJ which relies on a fixed rubber bumper, this MBLCJ variant features a screw-tunable adjustable air cushion at both ends to decelerate heavier loads smoothly and protect the end covers. The rear stopper sets the travel end but does not hold the load; the cushion only decelerates. Note this specific SKU lacks a built-in magnet, so it cannot accept a CMSG or DMSG position sensor.

| Series | MBL aluminum-barrel mini round cylinder (adjustable stroke) |
| Bore size | Ø25 mm |
| Nominal stroke | 150 mm |
| Adjustable window | 100–150 mm (trim 50 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 MBLCJ25X150-50 Is Used
Textile Loom Beat-Up
Provides 245 N of push force at 0.5 MPa to drive the loom reed, using the 100-150 mm adjustable window to perfectly time the fabric weave stroke.
Bottle Capper Heads
Uses the screw-tunable air cushion to gently decelerate the 150 mm stroke, preventing cap crushing while maintaining a fast 30-800 mm/s cycle speed.
Pallet Diverter Gate
Shifts lightweight pallets on a packaging line where the 206 N pull force easily retracts the 10 mm rod against the diverter arm spring tension.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X150-50 the Right Cylinder?
Stepping down to the Ø20 bore drops output to 157 N push at 0.5 MPa, while moving up to the Ø32 bore increases force to 402 N. Choose this 25 mm bore if your application requires 245 N push. The MBLCJ is ideal over the MBLJ when you need tunable end-of-stroke deceleration instead of a fixed bumper, and offers rear travel adjustment that the fixed-stroke MBLC lacks.
Neither the rear travel stopper nor the adjustable air cushion acts as a lock; the rod drifts without live air, so use an external locking device for position holding. Mounting is limited to Basic, FA flange, or LB foot options as there is no back-cover or SDB pivot available. For an exact replacement, match the 25 mm bore, 150 mm stroke, 50 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 MBLCJ25X150-50 FAQ
At 0.5 MPa, this double-acting cylinder provides 245 N push and 206 N pull. At 0.7 MPa, the push force is 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa.
No. This specific SKU lacks the -S code for a built-in magnet, so it cannot accept AirTAC CMSG reed or DMSG electronic sensors. You would need the MBLCJ25X150-50S variant for position detection.
