About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X175-30
The AirTAC MBLCJ50X175-30 is a compact double-acting mini cylinder featuring a riveted aluminum barrel and a single Ø16 mm hard-chrome plated carbon-steel rod. It integrates a rear travel stopper allowing you to trim up to 30 mm, creating a usable end-position window of 145-175 mm. Delivering 981 N of push force at 0.5 MPa, this 50 mm bore unit is built for substantial actuation tasks.
Distinct from the fixed bumper on an MBLJ, this model uses a screw-tunable adjustable air cushion at both ends to decelerate heavy loads smoothly. Note that this specific SKU lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensors. The rear stopper sets the travel end but does not lock the load, and the overall length equals A + 2 x 175 + 30 mm.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X175-30 Is Used
Injection Mold Ejection
Provides 981 N of push at 0.5 MPa to eject plastic parts from heavy molds, using the 145-175 mm stroke window to time the ejection length precisely.
Bottling Line Diverter
Tunes the end-of-stroke air cushion to softly deflect glass bottles onto a packaging belt, preventing impact breakage during high-speed routing.
Woodworking Press Feed
Handles timber feeding in a CNC router infeed system, where the 30 mm rear stroke adjustment accommodates varying raw board thicknesses without repositioning the cylinder.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X175-30 the Right Cylinder?
If you need less force, step down to the 40 mm bore (628 N push @0.5 MPa), or step up to the 63 mm bore (1558 N push @0.5 MPa) for heavier demands. Choose this MBLCJ over the MBLJ when your moving mass requires tunable end-of-stroke deceleration rather than a fixed rubber bumper, or over the MBLC if you need to fine-tune the travel end.
The rear adjuster is strictly a travel stop, not a lock; the cushion only decelerates, so external holding mechanisms are required for position retention. Mounting is limited to Basic, FA, or LB styles, with no SDB pivot or back-cover options available. For an exact replacement, match the 50 mm bore, 175 mm stroke, 30 mm adjust code, G1/4 port, PT thread, and confirm no magnet is fitted.
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 MBLCJ50X175-30 FAQ
At 0.5 MPa, this 50 mm bore cylinder provides 981 N push and 881 N pull force. At 0.7 MPa, the push force is 1374 N, with a theoretical maximum of 200 kgf at 1.0 MPa. The 50 mm bore supports standard strokes up to 500 mm.
This specific SKU lacks the -S magnet option, so it cannot accept CMSG, DMSG, or EMSG electronic position sensors. Additionally, the rear stroke adjuster is a travel stop, not a lock, and the adjustable air cushion only decelerates the load; neither feature will hold the rod position without live air pressure.
