About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ63X150-40
The AirTAC MBLCJ63X150-40 is a compact double-acting mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. The rear stopper allows you to trim up to 40 mm of travel, creating a usable working window of 110 to 150 mm. Driven by a Ø16 mm carbon-steel rod with 20 um hard-chrome plating, it delivers 1558 N of push force and 1457 N of pull force at 0.5 MPa. This 150 mm stroke suits heavy indexing and press operations.
The integrated adjustable air cushion uses screw-tunable deceleration to protect the end covers during high-velocity moves, unlike the fixed rubber bumper found on the MBLJ. The riveted aluminum barrel and grease-retaining piston seal ensure stable friction. Because this specific SKU lacks a built-in magnet (-S), it cannot support a CMSG, DMSG, or EMSG position sensor. The rear adjuster acts purely as a mechanical travel stop, not a load-holding lock.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ63X150-40 Is Used
Punch Press Ejection
Provides 1558 N of thrust at 0.5 MPa to eject stamped metal blanks, using the 40 mm rear stroke trim to dial in the exact ejection distance.
Heavy Pallet Stops
Halts loaded pallets on a conveyor using the tunable air cushion to decelerate the 318 kgf maximum force impact without slamming the end covers.
Woodworking Clamp Arms
Secures timber profiles for routing, leveraging the 110-150 mm usable stroke window to accommodate varying wood thicknesses dynamically.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ63X150-40 the Right Cylinder?
If you need less force, the 50 mm bore provides 981 N push at 0.5 MPa; for even higher thrust, stepping outside this mini series is required as 63 mm is the largest bore. Choose this MBLCJ over the MBLJ when your moving mass requires tunable end-of-stroke deceleration rather than a fixed bumper, or over the MBLC when you need to fine-tune the end position within that 110-150 mm window. The rear stopper sets the travel end but does not hold the load—external locking is needed for position holding. Mounting is limited to Basic, FA, or LB; no SDB or back-cover options exist. The replacement match is: 63 mm bore, 150 mm stroke, 40 mm adjust, G1/4 port, PT thread, Basic mounting, no 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 MBLCJ63X150-40 FAQ
At 0.5 MPa, this 63 mm bore cylinder provides 1558 N push and 1457 N pull force. At 0.7 MPa, the push force reaches 2181 N. The maximum theoretical force is 318 kgf at 1.0 MPa.
No, because this specific SKU does not have the -S code, it lacks a built-in magnet and cannot accept AirTAC CMSG, DMSG, or EMSG sensors. Additionally, the 40 mm rear adjuster is a travel stop, not a lock, so it will not hold the load without live air pressure.
