About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X350-50
The AirTAC MBLCJ32X350-50 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. It uses a G1/8 port, a Ø12 mm carbon-steel rod with 20 µm hard-chrome plating, and delivers 402 N push force at 0.5 MPa. The 50 mm adjustment code provides a usable travel window of 300 to 350 mm, suiting long-travel positioning tasks.
Unlike the base MBLJ with its fixed rubber bumper, this model uses screw-tunable end-of-stroke cushioning to decelerate heavier masses over 350 mm. The riveted rolling-packed barrel and heterogeneous two-way grease-retaining piston seal maintain lubrication. Note that this specific SKU lacks a built-in magnet, so it cannot accept CMSG, DMSG, or EMSG position sensors.

| Series | MBL aluminum-barrel mini round cylinder (adjustable stroke) |
| Bore size | Ø32 mm |
| Nominal stroke | 350 mm |
| Adjustable window | 300–350 mm (trim 50 mm) |
| Acting type | Double acting |
| Port size | G1/8 |
| Rod thread | M10×1.25 |

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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 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 MBLCJ32X350-50 Is Used
Textile Loom Let-Off
Drives the 300-350 mm tensioning arm on a weaving loom, using the tunable cushion to softly arrest the 402 N push force at high cycling speeds without jarring the yarn path.
Pallet Transfer Gate
Actuates a 350 mm diverter gate on a packaging conveyor, where the rear stroke adjuster dials in the exact end position to meet the pallet while the cushion prevents end-cover damage.
CNC Chip Conveyor
Pushes metal swarf along a 350 mm stroke within a CNC machining center, relying on the riveted aluminum barrel to withstand intermittent debris impacts while retracting smoothly.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X350-50 the Right Cylinder?
For lower force needs, stepping down to the 25 mm bore yields 245 N push at 0.5 MPa, while moving up to the 40 mm bore provides 628 N. Choose this MBLCJ over the fixed-stroke MBLC when you need to fine-tune the rear travel end within that 300-350 mm window. The rear adjuster acts only as a mechanical travel stop and the cushion only decelerates; neither holds a load, so external locking is required for position holding.
Mounting is limited to Basic, FA (flange), or LB (foot) styles; no SDB pivot or back-cover options exist. Because the overall length extends to A + 2 x stroke + adjust, the 350 mm travel combined with the small Ø12 mm rod makes this cylinder highly susceptible to side-load bending—an external guide rail is strongly recommended. Replacement parts must match the 32 mm bore, 350 mm stroke, 50 mm adjust code, PT thread, and no-magnet configuration.
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 MBLCJ32X350-50 FAQ
At 0.5 MPa, the push force is 402 N and the pull force is 346 N. At 0.7 MPa, the push force reaches 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa.
The 50 mm rear stroke adjuster mechanically limits the travel window to 300-350 mm, acting as a physical stop. The adjustable air cushion only tunes the end-of-stroke deceleration rate to protect the covers; neither system locks or holds the load in place.
