About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X200-40
The AirTAC MBLCJ40X200-40 is a compact double-acting mini cylinder featuring a single rod and a riveted aluminum barrel. It integrates a rear travel stopper yielding a 160-200 mm usable stroke window (trimming up to 40 mm from the 200 mm nominal length). Driven by a G1/4 port and a hard-chrome plated Ø16 rod, it delivers 628 N push and 528 N pull at 0.5 MPa, making it well-suited for mid-weight positioning tasks requiring exact end-of-travel placement.
Distinct from the fixed bumper on an MBLJ, this SKU employs a screw-tunable adjustable air cushion at both ends to regulate end-of-stroke deceleration, absorbing kinetic energy to protect the end covers during heavier 200 mm moves. The rear stopper sets the physical travel end but does not lock or hold the load—rod drift occurs without live air pressure. Note that this specific configuration omits the -S magnet, meaning it cannot accept CMSG, DMSG, or EMSG position sensors.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X200-40 Is Used
PCB Router Z-Axis
Drives the plunge cycle on a customized PCB depaneling router, using the 628 N push force to cleanly cut FR4 fiberglass substrates while the air cushion prevents end-cap impact.
Bottle Capper Heads
Applies torque-assisted downward pressure on rotary capping heads in a beverage line, utilizing the 160-200 mm stroke window to fine-tune cap seating depth on varying bottle heights.
Leather Skiving Press
Feeds material into an industrial leather skiving machine, where the 528 N pull force retracts the gauge plate and the tunable cushion allows smooth deceleration of the 200 mm stroke.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X200-40 the Right Cylinder?
Stepping down to the 32 mm bore drops the 0.5 MPa push force to 402 N, while moving up to the 50 mm bore increases it to 981 N. Choose this 40 mm bore when your payload requires roughly 628 N of push force at 0.5 MPa. The MBLCJ is preferred over the MBLJ when your moving mass demands tunable pneumatic cushioning rather than a fixed rubber bumper. For fixed travel without the rear adjuster, consider the MBLC series. Replacement matches require: 40 mm bore, 200 mm stroke, 40 mm adjust code, G1/4 port, PT thread, and Basic/FA/LB mounting (no SDB or back-cover options exist). At 200 mm stroke, the 16 mm rod is highly susceptible to side-load bending; an external guide rail is strongly recommended to prevent premature seal wear.
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 MBLCJ40X200-40 FAQ
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, the push force is 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa.
No. This specific SKU lacks the -S built-in magnet, so it cannot host CMSG, DMSG, or EMSG electronic switches. Additionally, the rear adjuster is a travel stop, not a lock; it sets the 160-200 mm window but does not hold the load pneumatically without live air.
