About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X175-40
The AirTAC MBLCJ50X175-40 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and an adjustable air cushion 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 40 mm of travel, creating a usable stroke window of 135-175 mm for precise end positioning. This 175 mm stroke suits longer linear transfers and heavy lifting tasks.
Unlike the fixed rubber bumper on an MBLJ, the screw-tunable air cushions on this unit decelerate heavy 50 mm bores smoothly at high speeds, protecting the end covers from impact. The riveted rolling-packed barrel and 20 um hard-chrome plated carbon-steel rod ensure durability. Because this specific SKU lacks the -S suffix, it has no built-in magnet and cannot support CMSG, DMSG, or EMSG position sensors.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X175-40 Is Used
Stamping Feeder Alignment
Pushes metal blanks into a stamping press using 981 N of force, relying on the 40 mm rear stroke adjustment to dial in the exact 135 mm insertion depth.
Packaging Conveyor Diverter
Diverts heavy cartons at high cycle speeds, using the dual adjustable air cushions to brake the 175 mm stroke smoothly without slamming the end covers.
Woodworking Panel Stop
Acts as an end-stop for sizing wooden panels, where the 881 N pull force retracts the rod quickly and the PT-threaded G1/4 port handles the required air volume.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X175-40 the Right Cylinder?
Step up to the 63 mm bore if you need greater thrust (1558 N push at 0.5 MPa), or step down to the 40 mm bore for lighter loads (628 N push at 0.5 MPa). Choose this MBLCJ over an MBLJ when your moving mass requires tunable pneumatic deceleration rather than a fixed bumper, or over an MBLC when you need to dial in the 135-175 mm travel window. The rear adjuster sets the travel end point and the cushion governs deceleration, but neither acts as a mechanical lock to hold a load in place.
Mounting is limited to Basic, FA flange, or LB foot styles; there is no back-cover or SDB pivot option. The overall length extends to A + 2 x stroke + adjust. This SKU uses a PT tapered port thread and a G1/4 port. For exact replacement matching, verify the 50 mm bore, 175 mm stroke, 40 mm adjust code, PT thread, and the absence of a magnet. At 175 mm, the 16 mm rod is robust, but external guidance is recommended to prevent side-load bending.
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 MBLCJ50X175-40 FAQ
At 0.5 MPa, this 50 mm bore cylinder provides 981 N of push force and 881 N of pull force. At 0.7 MPa, the push force increases to 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa.
This specific SKU lacks the -S suffix, meaning it has no built-in magnet and cannot accept CMSG, DMSG, or EMSG position sensors. The 40 mm rear adjuster is a travel stop that creates a 135-175 mm usable stroke window, while the adjustable air cushion tunes end-of-stroke deceleration; neither feature locks or holds the load.
