About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X50-10
The AirTAC MBLCJ40X50-10 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 10 mm of travel at the rear, creating a usable stroke window of 40 to 50 mm. With a 40 mm bore, it delivers 628 N push and 528 N pull force at 0.5 MPa, making it highly effective for mid-range actuation. This SKU lacks a built-in magnet, so it cannot accept a CMSG, DMSG, or EMSG position sensor.
The adjustable air cushion uses screw-tunable deceleration to protect the end covers during faster or heavier moves, a distinct advantage over the fixed rubber bumper found on the MBLJ series. The riveted rolling-packed aluminum barrel pairs with a heterogeneous two-way grease-retaining piston seal. The Ø16 carbon-steel rod features 20 µm hard-chrome plating to resist wear, and the overall length equals A + 2 x stroke + adjust. Remember, the rear stopper sets the travel end position; it does not hold the load in place.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X50-10 Is Used
PCB Conveyor Stopper
Provides 628 N of push force at 0.5 MPa to halt populated PCBs on a conveyor belt, using the 10 mm rear stroke trim to dial in the exact stopping distance without moving the cylinder body.
Pallet Deceleration
Tunable air cushions absorb the kinetic energy of a 50 mm stroke when rejecting light aluminum pallets, preventing end-cover damage on high-speed packaging lines.
Film Tensioning Roll
Applies 528 N of pull force to maintain tension on a web handling roller, with the hard-chrome plated Ø16 rod ensuring smooth, consistent movement in dusty environments.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X50-10 the Right Cylinder?
If you need less force, stepping down to the 32 mm bore yields 402 N push at 0.5 MPa, while stepping up to the 50 mm bore provides 981 N push for heavier payloads. Choose this MBLCJ over the MBLJ when your application requires tuned end-of-stroke deceleration rather than a fixed bumper, or over the MBLC when you need that rear travel adjustment. The rear adjuster is a travel stop, and the cushion only decelerates; neither acts as a lock, so use an external guide for side-load support on longer strokes. Mounting is limited to Basic, FA flange, or LB foot; there is no SDB pivot or back-cover option. To replace this exact unit, match the 40 mm bore, 50 mm stroke, 10 mm adjust code, G1/4 port, PT thread, and confirm no magnet is fitted.
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 MBLCJ40X50-10 FAQ
At 0.5 MPa, the 40 mm bore provides 628 N push and 528 N pull force. At 0.7 MPa, the push force increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa.
The rear stroke adjuster is a mechanical travel stop that limits the end position within a 40 to 50 mm window. The adjustable air cushion is a screw-tunable valve that decelerates the piston near the stroke ends. Neither mechanism locks the load in place.
