About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X160-50
The AirTAC MBLCJ40X160-50 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. You can trim up to 50 mm of travel at the rear, yielding a usable end-position window of 110 to 160 mm. Driven by a Ø16 mm carbon-steel rod with 20 µm hard-chrome plating, it delivers 628 N of push force and 528 N of pull force at 0.5 MPa. This 160 mm stroke suits mid-length indexing on packaging or assembly machinery.
Unlike the base MBLJ which relies on a fixed rubber bumper, this model uses screw-tunable end-of-stroke cushioning to smoothly decelerate heavier loads, protecting the end covers. The riveted rolling-packed barrel and heterogeneous two-way grease-retaining piston seal lock in lubrication for high cycle rates. Note that this specific SKU lacks a built-in magnet (-S), meaning it cannot accept CMSG, DMSG, or EMSG position sensors.

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a margin.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X160-50 Is Used
Carton Flap Folding
Drives mid-stroke folding arms on case erectors where the 628 N push force securely creases heavy corrugated board, while the tuned cushion halts the 160 mm travel softly.
Bottle Diverter Gates
Actuates stainless steel guide rails on filling lines, using the 110-160 mm adjustable window to precisely set lane width without moving cylinder mounting brackets.
Pallet Stopper Arms
Deploys mechanical stops at pallet strapping stations; the adjustable air cushion absorbs the kinetic energy of the descending 40 mm bore rod to prevent end-cover damage.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X160-50 the Right Cylinder?
Step down to the 32 mm bore if your load requires only 402 N of push force at 0.5 MPa, or step up to the 50 mm bore for 981 N to handle heavier payloads. Choose this MBLCJ over the MBLJ when your cycle speeds demand tunable pneumatic deceleration rather than a fixed rubber bumper. If your travel length is fixed, the MBLC provides the same cushioning without the rear adjuster.
The rear stroke adjuster is a mechanical travel stop, not a load-holding lock; the rod will drift without live air pressure, so use an external locking device for safety. Mounting is limited to Basic, FA (flange), or LB (foot) brackets—this series omits SDB pivot and back-cover options. For an exact replacement, match the 40 mm bore, 160 mm stroke, 50 mm adjust code, G1/4 port, PT thread, and confirm no magnet is fitted. At 160 mm stroke, support the rod externally 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 MBLCJ40X160-50 FAQ
At 0.5 MPa, this 40 mm bore cylinder provides 628 N push force and 528 N pull force. At 0.7 MPa, the push force increases to 880 N. The maximum operating pressure is 1.0 MPa, which yields a theoretical max force of 128 kgf.
No, this specific SKU lacks the -S code for a built-in magnet, so it cannot accept CMSG, DMSG, or EMSG sensors. The rear adjuster lets you trim up to 50 mm of travel, creating a 110-160 mm usable window. This adjuster is a travel stop, not a lock; the separate screw-tunable air cushion handles end-of-stroke deceleration.
