About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X400-20
The AirTAC MBLCJ32X400-20 is a compact double-acting mini cylinder featuring a rear travel stopper and an adjustable air cushion at both ends. It delivers 402 N of push force and 346 N of pull force at 0.5 MPa. The rear adjuster allows you to trim up to 20 mm of travel, creating a usable stroke window of 380 to 400 mm. This specific tuning capability makes it highly suitable for long-reach handling tasks that need precise end-positioning without mechanical crashes.
Unlike the base MBLJ which relies on a fixed rubber bumper, this model uses screw-tunable end-of-stroke deceleration to absorb kinetic energy from heavy 400 mm moves, protecting the aluminum end covers. The riveted rolling-packed barrel and 20 µm hard-chrome plated carbon-steel rod withstand industrial wear. Because this SKU lacks the -S magnet code, it cannot host a CMSG, DMSG, or EMSG position sensor. The overall length equals A + 2 x stroke + adjust, meaning the physical body extends significantly longer than the nominal travel.

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.

| 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 MBLCJ32X400-20 Is Used
PCB Conveyor Gating
Acts as a pop-up stop gate on a PCB conveyor line, using the 380-400 mm adjustable window to tune the stop position for varying board lengths while the air cushion prevents shock at high cycle rates.
Textile Beam Doffing
Extends to push empty textile beams onto a transfer carriage in a doffing machine, where the 402 N push force handles the weight and the dual cushions arrest the long 400 mm extension smoothly.
Carton Flap Ploughing
Drives a mechanical plough to fold minor flaps on a case packing machine, tuning the rear 20 mm adjuster to hit different carton widths while the end cushion softens the rapid retraction.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X400-20 the Right Cylinder?
When sizing this 32 mm bore, step down to the 25 mm bore if your load requires only 245 N of push force at 0.5 MPa, or step up to the 40 mm bore for 628 N if your mass demands heavier thrust. Choose this MBLCJ over the MBLJ when your 400 mm stroke speed requires tunable pneumatic deceleration rather than a fixed bumper. Keep in mind the rear stroke adjuster is strictly a mechanical travel stop, not a lock; it will not hold a load in place without continuous air pressure. Similarly, the cushion only decelerates the piston and does not brake or clamp the load. Mounting is limited to Basic, FA flange, or LB foot styles; there is no SDB pivot or back-cover option. For an exact replacement, match the 32 mm bore, 400 mm stroke, 20 mm adjust code, G1/8 PT port, and confirm no magnet is fitted. Because the stroke is 400 mm, the 12 mm rod is highly susceptible to side-load bending; an external guide rail is mandatory to prevent seal failure.
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 MBLCJ32X400-20 FAQ
At 0.5 MPa, the 32 mm bore provides 402 N of push force and 346 N of pull force. At 0.7 MPa, the push force reaches 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa.
This specific SKU lacks the -S magnet code, so it cannot accept a CMSG, DMSG, or EMSG position sensor. The rear 20 mm adjustment is a travel stop that sets the end position from 380 to 400 mm; it is not a lock and will not hold the load without live air pressure.
