About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X175-10
The AirTAC MBLCJ50X175-10 is a compact double-acting mini cylinder featuring a rear stroke adjuster and tunable air cushions at both ends. It delivers 981 N of push force and 881 N of pull force at 0.5 MPa. The rear stopper allows you to trim up to 10 mm of travel, creating a precise 165-175 mm usable stroke window for exact end positioning.
This 50 mm bore unit uses a G1/4 port and a Ø16 hard-chrome plated carbon steel rod. The adjustable air cushion is screw-tunable to decelerate heavy loads at the stroke ends, protecting the end covers from impact damage. Note that this specific SKU lacks a built-in magnet, so it cannot support CMSG, DMSG, or EMSG position sensors without physical modification.

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)

| 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 MBLCJ50X175-10 Is Used
PCB Router Z-Axis
Lifts and lowers a high-speed spindle on a PCB depaneling router, using the 165-175 mm stroke window to dial in the exact cutting depth limit while the air cushion absorbs the spindle head's downward momentum.
Stator Winding Press
Presses copper wire wedges into electric motor stators, utilizing the 981 N push force at 0.5 MPa and tuning the cushion to gently seat the wedges without crushing the insulation paper.
Packaging Carton Flap Folder
Folds heavy corrugated carton flaps on a continuous packaging line, relying on the 175 mm stroke and deceleration cushioning to prevent tearing the cardboard at the end of the folding cycle.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X175-10 the Right Cylinder?
Step down to the 40 mm bore if your application requires less force (628 N push at 0.5 MPa), or step up to the 63 mm bore for heavy-duty moves requiring 1558 N push. Choose this MBLCJ over the MBLJ when your moving mass needs screw-tunable end-of-stroke deceleration instead of a fixed rubber bumper. If exact 175 mm travel is not critical, the fixed-stroke MBLC offers the same cushioning without the rear adjuster.
Remember that the 10 mm rear adjuster is a travel stop, not a lock, and the air cushion only decelerates; neither will hold a load in place without continuous air pressure. Mounting is limited to Basic, FA flange, or LB foot styles, as this series omits SDB pivot and back-cover options. For a drop-in replacement, match the 50 mm bore, 175 mm stroke, 10 mm adjust code, G1/4 PT thread, and confirm no magnet is needed.
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 MBLCJ50X175-10 FAQ
At 0.5 MPa it provides 981 N push and 881 N pull. At 0.7 MPa push increases to 1374 N, with a theoretical maximum of 200 kgf at 1.0 MPa. The rear adjuster trims up to 10 mm of travel, giving a usable stroke window of 165 to 175 mm.
This specific SKU does not include a built-in magnet, so it cannot accept CMSG, DMSG, or EMSG electronic or reed sensors. Additionally, the 10 mm rear mechanism is a travel stop, not a lock, and the air cushion only controls deceleration; neither feature will hold a load in place without live air pressure.
