About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X200-40
The AirTAC MBLCJ50X200-40 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and tunable air cushions at both ends. The 40 mm adjuster trims the rear travel, yielding a usable stroke window of 160 to 200 mm. Delivering 981 N of push force at 0.5 MPa, this 200 mm unit suits mid-weight positioning tasks that need precise end-of-travel tuning rather than a fixed rubber bumper.
It uses a G1/4 port, a Ø16 hard-chrome plated carbon steel rod, and a riveted rolling-packed barrel. The adjustable air cushion allows screw-tuned deceleration to absorb kinetic energy at the stroke ends, protecting the end covers during faster moves. Note that this specific SKU lacks a built-in magnet (-S), meaning it cannot support CMSG, DMSG, or EMSG position sensors. The rear stopper sets the travel end but does not lock the load, and overall length equals A + 2 x stroke + adjust.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X200-40 Is Used
Injection Mold Ejection
Provides 981 N of push force to eject plastic parts from molds, using the 160-200 mm adjustable stroke window to fine-tune the ejection distance precisely.
Packaging Flap Folding
Tunes the adjustable air cushion to gently decelerate the 200 mm stroke when folding heavy cardboard flaps, preventing impact damage to the packaging machine.
Pallet Diverting
Handles mid-weight pallet diversion on conveyors where the 881 N pull force retracts the diverter arm, while the rear stopper sets the exact extended position.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X200-40 the Right Cylinder?
Choose this 50 mm bore when you need 981 N push force at 0.5 MPa alongside a 160-200 mm adjustable stroke window. If your application is lighter, the 40 mm bore offers 628 N push force; if you need more power, stepping up to the 63 mm bore provides 1558 N. This model uses a G1/4 port and M14x1.5 rod thread, with standard PT thread form.
Compared to the MBLJ (which relies on a fixed bumper), this MBLCJ variant provides tunable end-of-stroke cushioning for heavier loads. Unlike the MBLC, it also adds the 40 mm rear travel adjuster. Mounting is limited to Basic, FA (flange), or LB (foot) — there is no back-cover or SDB pivot option. Neither the cushion nor the rear stopper acts as a lock; use an external guide to prevent rod bending on this 200 mm stroke. Replacement matches: 50 mm bore, 200 mm stroke, 40 mm adjust, G1/4 port, PT thread, no magnet.
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 MBLCJ50X200-40 FAQ
At 0.5 MPa, this 50 mm bore cylinder provides 981 N push and 881 N pull force. At 0.7 MPa, push increases to 1374 N, with a maximum theoretical output of 200 kgf at 1.0 MPa. The rear adjuster is a travel stop and the cushion only decelerates; neither holds position pneumatically, so the rod will drift without live air.
No, this specific MBLCJ50X200-40 SKU does not include a built-in magnet (-S code), meaning it cannot support AirTAC CMSG (reed) or DMSG/EMSG (electronic) sensor switches. You would need the -S variant of this model for position detection.
