About the Airtac MBLJ Adjustable Aluminum Alloy Mini Cylinder MBLJ63X160-30S
The AirTAC MBLJ63X160-30S is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster. A built-in stopper screw lets you trim the extend travel by up to 30 mm, creating a usable end-position window of 130 to 160 mm without external stops. Driven by a Ø16 carbon-steel rod with 20 um hard-chrome plating, it delivers 1558 N push and 1457 N pull force at 0.5 MPa. The riveted rolling-packed barrel and heterogeneous grease-retaining piston seal ensure stable friction for demanding cycles.
This SKU includes a built-in magnet (-S) for position detection via AirTAC CMSG reed or DMSG/EMSG electronic switches. The fixed rubber bumper softens end impact, while the rear adjuster sets the travel limit. Note that the adjuster and bumper act as travel stops, not locks; the rod will drift if air pressure is removed. With a G1/4 port and M14x1.5 rod-end thread, overall length equals A + 2 x stroke + adjust, making it longer than a fixed MBL but highly versatile for product changeovers.

Where the Airtac MBLJ Adjustable Aluminum Alloy Mini Cylinder MBLJ63X160-30S Is Used
Injection Mold Ejection
Delivers 1558 N of push force at 0.5 MPa to eject dense plastic parts, using the 30 mm rear adjuster to fine-tune the 130-160 mm stroke for varying mold depths.
Packaging Flap Folding
Adjusts the end position on the fly during carton size changeovers, using the -S magnet with a DMSG electronic sensor to verify the fold completion.
Wood Board Pressing
Provides reliable clamping with 1457 N pull force at 0.5 MPa, relying on the fixed rubber bumper to absorb the impact of pressing laminate sheets.
Is the Airtac MBLJ Adjustable Aluminum Alloy Mini Cylinder MBLJ63X160-30S the Right Cylinder?
Choose this 63 mm bore when high thrust is required in a compact footprint. If you need less force, stepping down to the 50 mm bore yields 981 N push at 0.5 MPa. If you require even greater push power, the 63 mm is the largest available MBLJ size, offering 2181 N at 0.7 MPa and a maximum theoretical 318 kgf at 1.0 MPa. The PT threaded G1/4 port handles the necessary air volume for these high forces.
Select this adjustable variant over a fixed MBL when you need to fine-tune the 130-160 mm end position during commissioning or product changeovers. If your application suffers from severe end-impact shock, consider the MBLCJ variant which adds an adjustable air cushion. Mounting is limited to Basic, FA flange, or LB foot styles; there is no SDB pivot or back-cover option. To replace this cylinder, match the 63 mm bore, 160 mm stroke, 30 mm adjust code, G1/4 port, PT thread, and the -S magnet. For a 160 mm stroke, ensure external guides support side loads to prevent bending the 16 mm rod.
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 MBLJ63X160-30S FAQ
At 0.5 MPa, this double-acting cylinder provides 1558 N push and 1457 N pull force. At 0.7 MPa, push increases to 2181 N. The maximum theoretical force is 318 kgf at 1.0 MPa. The 160 mm stroke can be trimmed by up to 30 mm at the rear, giving an adjustable usable end-position window of 130 to 160 mm.
No. The rear stopper is a travel stop that sets the end position, not a lock or brake. The fixed rubber bumper only softens the impact at the end of travel. The rod will drift if air pressure drops, so an external locking device is required for fail-safe load holding. The -S magnet works with CMSG, DMSG, and EMSG sensors to monitor position.
