About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X500-50S
The AirTAC MBLCJ32X500-50S is a compact double-acting aluminum mini cylinder engineered for long-travel tasks requiring precise end-control. It features a rear adjustable stroke stopper that permits a 50 mm trim, creating a usable end-position window of 450 to 500 mm. Delivering 402 N of push force at 0.5 MPa, this 32 mm bore unit integrates an adjustable air cushion at both ends to tune deceleration for heavy 500 mm moves. The built-in magnet (-S) enables position detection via CMSG reed or DMSG and EMSG solid-state sensors.
This model distinguishes its rear travel stopper from its end-of-stroke cushioning: the stopper sets the exact travel end, while the screw-tunable cushion regulates impact speed to protect the end covers. The riveted rolling-packed aluminum barrel and 20 µm hard-chrome plated carbon-steel rod ensure durability. Because the 500 mm stroke pushes the 32 mm bore to its maximum standard limit, the 12 mm rod is highly susceptible to side loads—always use an external guide to prevent rod bending.

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 MBLCJ32X500-50S Is Used
Printed Circuit Board Shuttle
Transports PCB racks along a 450-500 mm windowed path. The tunable air cushion decelerates the 402 N thrust smoothly at transfer ends, protecting delicate solder joints from impact shock.
Packaging Lane Diverter
Pushes cartons across a wide sorting belt using the full 500 mm stroke. The rear adjuster allows precise 50 mm trimming to match varying box sizes without repositioning the entire cylinder assembly.
Textile Beam Indexing
Shifts heavy fabric beams into a winding station. The DMSG solid-state sensor confirms full extension, while the adjustable cushion absorbs the kinetic energy of the 346 N pull force during rapid retraction.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X500-50S the Right Cylinder?
Step down to the 25 mm bore if your payload is lighter (offering 245 N push at 0.5 MPa), or step up to the 40 mm bore for heavier loads (628 N push at 0.5 MPa). Choose this MBLCJ over the MBLJ if your application moves substantial mass at speed and needs tunable pneumatic cushioning rather than a fixed rubber bumper. If your end position never changes, the MBLC (fixed stroke + cushion) offers a shorter overall length.
The rear adjuster and the air cushion regulate travel and speed, but neither holds the load pneumatically; rod drift occurs without live air, so use an external locking mechanism for true position holding. Mounting is limited to Basic, FA, or LB styles (no SDB or back-cover options). For exact replacement, match the 32 mm bore, 500 mm stroke, 50 mm adjust code, G1/8 port, PT thread, and the -S magnet. At 500 mm, the side-load risk is critical—an external guide rail is mandatory to prevent premature seal failure.
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 MBLCJ32X500-50S FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 346 N of pull force. At 0.7 MPa, the push force increases to 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa.
The adjustable stroke is a rear mechanical stopper that trims the travel end within a 450-500 mm window. The adjustable air cushion is a screw-tunable valve that regulates end-of-stroke deceleration. Neither acts as a lock; the rod will drift without live air pressure.
