About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X150-50
The AirTAC MBLCJ40X150-50 is a compact double-acting aluminum mini cylinder featuring a rear travel stopper and an adjustable air cushion at both ends. It delivers 628 N of push force and 528 N of pull force at 0.5 MPa. The rear adjuster trims up to 50 mm of travel, creating a usable 100-150 mm stroke window ideal for varying machine clearances.
Unlike the fixed rubber bumper found on the base MBLJ, the screw-tunable cushion on this model decelerates heavier loads near the stroke ends to protect the end covers. The riveted rolling-packed barrel and grease-retaining piston seal maintain consistent lubrication. This SKU lacks a built-in magnet, so it cannot support CMSG, DMSG, or EMSG position sensors.

The rear stopper sets the end position — it is a travel stop, not a lock. Overall length = A + 2 × stroke + adjustable stroke. MBLJ/MBLCJ mounting is Basic / FA / LB only (no SDB, no back-cover code). Thread options: PT / G / NPT.
Theoretical Output Force (Ø40mm)

| 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 MBLCJ40X150-50 Is Used
CNC Lathe Bar Feeder
Pushes raw bar stock into the spindle with 628 N of force, using the 100-150 mm stroke window to compensate for varying material lengths while the air cushion prevents harsh end-impacts.
Thermoforming Mold Press
Closes a localized forming mold with 528 N of pull force at 0.5 MPa, relying on the screw-tunable cushion to slow the 150 mm travel before the final form to protect the tooling.
Pallet Squaring Stop
Acts as an adjustable physical stop for incoming pallets on a packaging line, trimming 50 mm at the rear to adapt to different pallet widths without repositioning the cylinder.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X150-50 the Right Cylinder?
This 40 mm bore provides 628 N of thrust at 0.5 MPa. If your application requires less force, step down to the 32 mm bore (402 N push). If you need to move heavier assemblies, step up to the 50 mm bore (981 N push). Choose the MBLCJ over the MBLJ when your moving mass demands tunable end-of-stroke deceleration rather than a fixed bumper, or over the MBLC when you need to fine-tune the end position.
The rear adjuster sets the travel end and the cushion only decelerates; neither holds the load, so use an external locking mechanism for position holding. Mounting is limited to Basic, FA (flange), or LB (foot) as there is no SDB pivot or back-cover option. Because the overall length equals A + 2 x stroke + adjust, verify your envelope. For a drop-in replacement, match the 40 mm bore, 150 mm stroke, 50 mm adjust code, G1/4 port, PT thread, and the lack of an S 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 MBLCJ Adjustable Mini Cylinder MBLCJ40X150-50 FAQ
At 0.5 MPa, this 40 mm bore cylinder provides 628 N of push force and 528 N of pull force. At 0.7 MPa, the push force reaches 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa.
No, the rear adjuster is a travel stop that sets the end position within the 100-150 mm window, and the adjustable air cushion only decelerates the load. Neither component locks or holds the load pneumatically; an external mechanical lock is required for position holding.
