About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X500-10S
The AirTAC MBLCJ50X500-10S is a compact double-acting mini cylinder with a single rod and an aluminum riveted barrel. It features a rear travel stopper allowing you to trim up to 10 mm, creating a precise usable stroke window of 490 to 500 mm. Equipped with an adjustable air cushion at both ends, it provides screw-tunable deceleration to absorb heavy kinetic energy, delivering 981 N of push force at 0.5 MPa.
This model includes a built-in magnet (-S) for compatibility with AirTAC CMSG reed and DMSG or EMSG electronic solid-state sensor switches. The 16 mm carbon-steel rod features 20 um hard-chrome plating to resist wear, while the heterogeneous two-way grease-retaining piston seal maintains lubrication. Remember the rear stopper sets the end position; it does not hold the load, and the cushion only decelerates.

| Series | MBL aluminum-barrel mini round cylinder (adjustable stroke) |
| Bore size | Ø50 mm |
| Nominal stroke | 500 mm |
| Adjustable window | 490–500 mm (trim 10 mm) |
| Acting type | Double acting |
| Port size | G1/4 |
| Rod thread | M14×1.5 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |

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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 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 MBLCJ50X500-10S Is Used
Injection Mold Ejection
Provides 981 N of push at 0.5 MPa to eject heavy plastic parts, using the 10 mm stroke trim to dial in the exact ejection height and the air cushion to halt the 500 mm travel smoothly.
Long-Stroke Conveyor Diverter
Shifts heavy pallets across a 500 mm gap, relying on the tunable cushioning to prevent end-cover damage during rapid 30-800 mm/s positioning cycles.
Automated Press Clamping
Holds large workpieces with 881 N of pull force, using the integrated magnet to trigger a DMSG solid-state sensor and confirm clamp engagement before the press cycles.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X500-10S the Right Cylinder?
Stepping down to the 40 mm bore reduces thrust to 628 N at 0.5 MPa, whereas stepping up to the 63 mm bore yields 1558 N. Choose this 50 mm bore when your payload requires nearly a kilonewton of push force. The MBLCJ differs from the MBLJ by offering tunable air cushioning instead of a fixed rubber bumper, and from the MBLC by adding the rear stroke adjuster. For replacements, match the 50 mm bore, 500 mm stroke, 10 mm adjust code, G1/4 port, PT thread, and the -S magnet. Mounting is limited to Basic, FA, or LB; no SDB or back-cover options exist. At 500 mm stroke, the 16 mm rod is highly susceptible to side-load bending—an external guide rail is mandatory.
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 MBLCJ50X500-10S FAQ
At 0.5 MPa it provides 981 N push and 881 N pull. At 0.7 MPa push increases to 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa.
The rear stopper lets you trim the stroke by 10 mm, giving a usable travel window of 490 to 500 mm. This mechanical stopper sets the end position but does not lock or hold the load, while the separate adjustable air cushion only controls deceleration speed.
