About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X200-30
The AirTAC MBLCJ50X200-30 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and tunable air cushions at both ends. It delivers 981 N of push force at 0.5 MPa via a Ø16 carbon-steel rod with 20 µm hard-chrome plating. The rear stopper trims up to 30 mm of travel, creating a usable 170-200 mm end-position window for precise machinery spacing. This SKU uses a PT-threaded G1/4 port and has no built-in magnet, meaning it cannot host a CMSG or DMSG sensor.
Unlike the base MBLJ with its fixed rubber bumper, this MBLCJ variant uses screw-tunable end-of-stroke deceleration to absorb kinetic energy from heavy 200 mm moves, protecting the end covers. The riveted rolling-packed barrel and heterogeneous two-way grease-retaining piston seal maintain lubrication for speeds of 30-800 mm/s. Remember the adjuster is a travel stop, not a load lock; the cylinder drifts without live air pressure.

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 MBLCJ50X200-30 Is Used
Injection Mold Ejection
Uses the 170-200 mm adjustable window to time the exact ejection stroke for plastic parts, while the tunable cushion decelerates the 981 N push force smoothly to protect mold faces.
Pallet Diverting
Diverts heavy pallets on a packaging line, relying on the 1374 N push at 0.7 MPa and the adjustable air cushion to stop the 200 mm travel without slamming the end cap.
Press Feed Stops
Acts as a feed stopper in a metal stamping press, using the 30 mm rear trim to dial in the metal strip position without re-mounting the cylinder.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X200-30 the Right Cylinder?
With a 981 N push at 0.5 MPa, this 50 mm bore suits mid-weight positioning. If you need less force, step down to the 40 mm bore (628 N push); for heavier loads, step up to the 63 mm bore (1558 N push). Choose this MBLCJ over the MBLJ when your moving mass requires tunable pneumatic deceleration instead of a fixed bumper, or over the MBLC if you need that 170-200 mm adjustable end-position window.
For a drop-in replacement, match the 50 mm bore, 200 mm stroke, 30 mm adjust code, G1/4 port, PT thread, and Basic mounting. Mounting is limited to Basic, FA flange, or LB foot—no SDB pivot or back-cover options exist. Because the overall length equals A + 2 x stroke + adjust, this cylinder is relatively long; for any stroke approaching 300 mm or beyond, you must use an external guide to prevent the Ø16 rod from bending under side loads.
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 MBLCJ50X200-30 FAQ
At 0.5 MPa, the push force is 981 N and the pull force is 881 N. At 0.7 MPa, the push force is 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa.
No. This specific SKU lacks the -S code, meaning no magnet is fitted and it cannot accept AirTAC CMSG, DMSG, or EMSG position sensors. You must select an MBLCJ model with the -S suffix for sensor capability.
