About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X175-50
The AirTAC MBLCJ40X175-50 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and a screw-tunable air cushion at both ends. With a 40mm bore, it delivers 628N push and 528N pull force at 0.5 MPa. The rear stopper allows you to trim up to 50mm of travel, creating a precise usable stroke window of 125-175mm for varying workpiece heights. This unit uses a PT tapered port thread and lacks a built-in magnet, meaning it cannot accept CMSG, DMSG, or EMSG position sensors.
Distinguish the rear travel stop from the adjustable cushion: the stopper sets the end position, while the needle valves tune end-of-stroke deceleration to protect the end covers from impact. Neither mechanism locks the load; you need external guide rails to manage side loads on the 16mm chrome rod, especially since the riveted barrel construction extends overall length. This cylinder accepts Basic, FA, or LB mounts only.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X175-50 Is Used
Pallet Dispenser Pusher
Drives pallets into a wrapping station using the 125-175mm stroke window, relying on the tunable cushion to softly stop an 880N load at 0.7 MPa.
Diversion Arm Mechanism
Actuates a routing gate on a packaging line, using the 628N push force to pivot heavy cardboard bundles smoothly without end-cover impact.
Press Fixture Ejector
Ejects stamped metal parts from a die set, trimming the rear 50mm stopper to adapt to varying part thicknesses on the fly.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X175-50 the Right Cylinder?
If your application requires less force, step down to the 32mm bore (402N push at 0.5 MPa); for heavier payloads, step up to the 50mm bore (981N push at 0.5 MPa). Choose this MBLCJ over the MBLJ if your cycle speed demands tunable deceleration rather than a fixed rubber bumper, or over the MBLC if you need variable end positions. Remember that the rear adjuster is a hard travel stop, not a load-holding brake. When replacing this cylinder, match the 40mm bore, 175mm stroke, 50mm adjust code, G1/4 port, PT thread, and confirm no magnet is required.
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 MBLCJ40X175-50 FAQ
At 0.5 MPa, this 40mm bore cylinder provides 628N push force and 528N pull force. At 0.7 MPa, the push force is 880N. The maximum theoretical force is 128 kgf at 1.0 MPa.
No. This specific SKU lacks the -S code, meaning no built-in magnet is fitted. You cannot mount AirTAC CMSG, DMSG, or EMSG electronic switches to detect rod position.
