About the Airtac MBLJ Adjustable Aluminum Alloy Mini Cylinder MBLJ50X300-10
The AirTAC MBLJ50X300-10 is a compact double-acting aluminum mini cylinder featuring a rear travel stopper that trims the stroke end position. You get a usable extension window of 290-300 mm, allowing precise 10 mm fine-tuning at commissioning without external stops. Driven by a Ø16 mm hard-chrome plated carbon steel rod, it delivers 981 N push and 881 N pull at 0.5 MPa. The riveted rolling-packed barrel and grease-retaining piston seal ensure reliable service in tight spaces.
This SKU lacks the -S magnet option, so it cannot host a CMSG, DMSG, or EMSG position sensor. Impact at the travel end is absorbed by a fixed rubber bumper. Because the overall length equals A + 2 x stroke + adjust, this 300 mm unit is physically long; an external guide is recommended to prevent rod bending under side loads.

Where the Airtac MBLJ Adjustable Aluminum Alloy Mini Cylinder MBLJ50X300-10 Is Used
Long-Reach Ejector
Ejects molded plastic parts from a 300 mm deep press bed, using the 981 N thrust at 0.5 MPa to break the vacuum and push components clear of the cavity.
Packaging Flap Folder
Deploys a 290-300 mm arm to fold corrugated carton flaps, using the 10 mm rear stroke adjustment to perfectly time the fold without repositioning the cylinder mount.
Textile Fabric Take-Up
Traverses a fabric guide roll across a 300 mm stroke, relying on the fixed rubber bumper to soften the rapid end-of-stroke impact during high-speed web handling.
Is the Airtac MBLJ Adjustable Aluminum Alloy Mini Cylinder MBLJ50X300-10 the Right Cylinder?
Choose this 50 mm bore when you need roughly 981 N of push force at 0.5 MPa. If your payload is lighter, step down to the 40 mm bore (628 N push); if you need heavier thrust, step up to the 63 mm bore (1558 N push). This cylinder uses a G1/4 port and an M14x1.5 rod-end thread.
The rear stopper on this MBLJ variant sets the 290-300 mm end position but is not a lock—the rod will drift without live air. Mounting is limited to Basic, FA flange, or LB foot (no SDB or back-cover options). For applications needing adjustable end cushioning rather than stroke trimming, select the MBLCJ variant. To replace this unit, match the 50 mm bore, 300 mm stroke, 10 mm adjust code, PT thread, and lack of a 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 MBLJ Adjustable Aluminum Alloy Mini Cylinder MBLJ50X300-10 FAQ
At 0.5 MPa it provides 981 N push and 881 N pull. At 0.7 MPa the push increases to 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa. The 10 mm rear adjuster creates a usable stroke window of 290-300 mm.
No. This specific SKU does not have the -S built-in magnet, so it cannot host AirTAC CMSG (reed) or DMSG/EMSG (electronic) switches. You would need the MBLJ50X300-10S variant for position detection.
