About the Airtac MBLJ Adjustable Aluminum Alloy Mini Cylinder MBLJ20X160-50
The AirTAC MBLJ20X160-50 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster. A rear screw lets you trim the extend end position by up to 50 mm, creating a usable travel window of 110-160 mm. It delivers 157 N push and 132 N pull force at 0.5 MPa from a 20 mm bore. This 160 mm stroke suits medium-travel pick-and-place or gating tasks in tight machine bays.
This SKU has no built-in magnet, so it cannot host a CMSG or DMSG position sensor. The riveted rolling-packed aluminum barrel and heterogeneous two-way grease-retaining piston seal ensure stable friction, while the Ø8 carbon-steel rod with 20 µm hard-chrome plating resists wear. End impact is absorbed by a fixed rubber bumper. The rear stopper only sets travel limits; it does not lock the load without continuous air pressure.

Where the Airtac MBLJ Adjustable Aluminum Alloy Mini Cylinder MBLJ20X160-50 Is Used
PCB Router Gating
Drives a lightweight pneumatic gate that routes printed circuit boards between two test stations, using the 110-160 mm window to fine-tune the gate open position during product changeovers.
Filament Spool Tensioning
Applies 157 N of push force at 0.5 MPa to maintain tension on a 3D printing filament spool arm, trimming the 50 mm rear stopper to set the exact slack-release point.
Small Parts Ejector
Ejects small plastic clips from an injection mold cavity over a 160 mm travel path, relying on the fixed rubber bumper to soften the end impact without needing an external shock absorber.
Is the Airtac MBLJ Adjustable Aluminum Alloy Mini Cylinder MBLJ20X160-50 the Right Cylinder?
Choose this 20 mm bore if you need 157 N push at 0.5 MPa over a 110-160 mm adjustable window. Stepping down to a 16 mm bore drops force, while stepping up to a 25 mm bore yields 245 N push at 0.5 MPa for heavier resistance. Because this is the base MBLJ, it uses a fixed rubber bumper; choose the MBLCJ variant if your payload requires adjustable pneumatic cushioning. For a fixed end position without the adjustment screw, select the standard MBL cylinder.
The rear adjuster is a mechanical travel stop, not a locking device; the rod will drift if air pressure drops. Mounting is limited to Basic, FA flange, or LB foot brackets—no SDB pivot or back-cover CA/U options exist. The port is G1/8 and the rod-end thread is M8x1.25. With a 160 mm stroke on an Ø8 rod, you should use an external guide rail to prevent rod bending and side-load damage. Replacement requires matching the 20 mm bore, 160 mm stroke, 50 mm adjust code, PT thread, and no-magnet configuration.
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 MBLJ20X160-50 FAQ
At 0.5 MPa it provides 157 N push and 132 N pull force. At 0.7 MPa the push force reaches 220 N. The theoretical maximum force is 32 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa, with a proof pressure of 1.5 MPa.
The rear screw lets you shorten the nominal 160 mm stroke by up to 50 mm, giving a usable end-position window of 110-160 mm. This adjuster is a travel stop, not a lock; it will not hold a load without live air. Because this specific SKU lacks the -S magnet code, it cannot accept a CMSG or DMSG sensor switch.
