About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X200-30
The AirTAC MBLCJ40X200-30 is a compact, double-acting mini cylinder featuring a single rod and a riveted aluminum barrel. It combines a rear travel stopper with an adjustable air cushion at both ends, delivering 628 N of push force and 528 N of pull force at 0.5 MPa. The integrated rear adjuster allows you to trim up to 30 mm of travel, creating a usable stroke window of 170 to 200 mm, making it ideal for varying machine formats.
Unlike the fixed rubber bumper found on the MBLJ variant, the screw-tunable air cushion on this unit decelerates the rod near the end of its stroke to prevent end-cover damage during heavier, fast moves. The 20 µm hard-chrome plated carbon-steel rod resists wear, while the heterogeneous two-way grease-retaining piston seal maintains lubrication over a 30-800 mm/s speed range. Note that this specific SKU lacks a built-in magnet, so it cannot accept 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)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 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 MBLCJ40X200-30 Is Used
Thermoforming Press
Provides 628 N of push at 0.5 MPa to close medium-sized mold frames, using the 170-200 mm stroke window to compensate for varying material thicknesses.
Bottling Line Diverter
Uses the adjustable air cushion to smoothly decelerate a heavy routing gate at the end of a 200 mm travel, preventing fluid splash and mechanical shock.
Pallet Stacker Arm
Lifts stacked components with 528 N of pull force, relying on the tunable end-cushioning to protect the riveted aluminum end covers during fast vertical cycles.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X200-30 the Right Cylinder?
Stepping down to the 32 mm bore reduces output to 402 N push at 0.5 MPa, whereas stepping up to the 50 mm bore increases thrust to 981 N push at 0.5 MPa. Choose the MBLCJ over the MBLJ when your moving load requires tuned end-of-stroke deceleration rather than a fixed bumper impact, or over the MBLC if you need to trim the 200 mm travel down to a 170 mm minimum. The rear adjuster acts solely as a travel stop and the cushion only decelerates; neither holds the load, so external locking is needed for position holding.
Mounting is limited to Basic, FA (flange), or LB (foot) styles, as this series omits the SDB pivot and back-cover options. The overall length equals A + 2 x 200 + 30 mm, so verify your envelope. For a direct replacement, match the 40 mm bore, 200 mm stroke, 30 mm adjust code, G1/4 port, PT thread, and the non-magnet configuration. At this 200 mm stroke, the 16 mm rod is susceptible to side-load bending, so guide the load externally.
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 MBLCJ40X200-30 FAQ
At 0.5 MPa, the 40 mm bore delivers 628 N push and 528 N pull. At 0.7 MPa, the push force is 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
The rear adjuster physically stops the rod, trimming the 200 mm travel down to a 170 mm minimum. The adjustable air cushion is a screw-tunable valve that bleeds air to decelerate the load near the end caps. Neither mechanism locks or holds the load in place.
