About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X400-20S
The AirTAC MBLCJ32X400-20S 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 20 mm of travel at the rear, giving an exact usable end-position window of 380 to 400 mm. Driven by a Ø12 mm hard-chrome plated carbon-steel rod through a G1/8 port, it delivers 402 N push and 346 N pull at 0.5 MPa. The built-in magnet (-S) supports CMSG reed and DMSG or EMSG solid-state sensors for position detection.
This 400 mm stroke length suits long-traverse pick-and-place units where end-cover impact is a risk. The screw-tunable cushion decelerates the piston near each end-cap, absorbing kinetic energy that a fixed rubber bumper cannot handle. Remember the rear stopper sets the travel endpoint but does not lock the load; the cushion only decelerates. With a 400 mm extension on a 12 mm rod, you must use an external guide to prevent side-load bending and premature seal wear.

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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 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 MBLCJ32X400-20S Is Used
PCB Conveyor Transfer
Moves populated PCB panels between inspection stages using the 402 N push force and 400 mm travel, with the air cushion preventing sudden jolts to delicate solder joints.
Carton Flap Plow
Guides packaging carton flaps during high-speed case erecting, using the 20 mm rear stroke adjustment to fine-tune the plow end-point for varying carton widths.
Textile Beam Indexing
Shifts heavy textile beams into the loom cradle, relying on the tunable air cushion to decelerate the 400 mm traverse and protect the riveted aluminum end covers.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X400-20S the Right Cylinder?
Step down to the 25 mm bore if your load requires only 245 N push at 0.5 MPa, or step up to the 40 mm bore for 628 N push if moving heavier tooling. Choose this MBLCJ over the MBLJ when you need tunable end-deceleration rather than a fixed bumper, or over the MBLC when you require a rear travel stopper to dial in the 380-400 mm window. The adjuster and cushion manage motion but neither holds position under load—use an external locking mechanism for static holding. Mounting is limited to Basic, FA flange, or LB foot; no SDB pivot or back-cover options exist. For a drop-in replacement, match the 32 mm bore, 400 mm stroke, 20 mm adjust code, G1/8 PT port, and -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 MBLCJ32X400-20S FAQ
At 0.5 MPa it provides 402 N push and 346 N pull. At 0.7 MPa the push force is 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa.
The rear stroke adjuster physically stops the piston to set a 380-400 mm travel window, but it does not lock the load. The adjustable air cushion only decelerates the piston near the end-caps to absorb impact; it also does not hold position.
