About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X40-40S
The AirTAC MBLCJ32X40-40S is a compact double-acting mini cylinder featuring a Ø32 mm bore, a Ø12 mm carbon-steel rod, and an integrated magnet for position detection. It delivers 402 N of push force and 346 N of pull force at 0.5 MPa. A rear travel stopper allows you to trim up to 40 mm of the 40 mm nominal stroke, yielding a usable extension window of 0 to 40 mm for precise short-stroke positioning. Unlike the base MBLJ which relies on a fixed rubber bumper, this variant incorporates a screw-tunable air cushion at both ends to smoothly decelerate the piston near the stroke extremes.
The riveted aluminum barrel keeps the body lightweight for tight machine layouts, while the 20 µm hard-chrome plating on the rod defends against wear and scoring. Because the 40 mm adjustable stroke consumes the entire base travel, the overall length is maximized early, giving you a long, rigid mounting footprint in a short-stroke application. The built-in -S magnet supports AirTAC CMSG reed switches and DMSG or EMSG solid-state electronic sensors for exact end-of-travel confirmation. Remember that the rear stopper sets the travel end and the cushion only decelerates; neither component mechanically locks the load in place.

| 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 MBLCJ32X40-40S Is Used
PCB Depaneling Saw Feed
Drives a circular saw blade carriage in a depaneling router, using the 0-40 mm stroke window to dial in the exact cut depth for different board thicknesses while relying on the air cushion to arrest the carriage smoothly.
Dispenser Valve Pin Lift
Actuates the metering pin on a pneumatic adhesive dispenser, where the 346 N pull force retracts the needle and the tunable cushion prevents fluid splashing by softening the rapid upstroke.
Connector Alignment Stop
Serves as an adjustable mechanical stop for a connector insertion head, trimming the stroke down to 15 mm to set precise insertion depth without re-machining the fixture.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X40-40S the Right Cylinder?
If 402 N of push force is excessive for your payload, stepping down to the Ø25 mm bore yields 245 N at 0.5 MPa, whereas moving up to the Ø40 mm bore provides 628 N for heavier actuation. Choose this MBLCJ variant over the MBLJ when your dynamics require tuned end-of-stroke deceleration to protect the end covers from impact shock, or select the MBLC if you prefer a fixed stroke without the rear adjuster. For exact replacements, verify the 32 mm bore, 40 mm stroke, 40 mm adjust code, G1/8 port with PT threads, Basic/FA/LB mounting (no SDB or back cover available), and the -S magnet specification. The adjuster acts purely as a travel stop and the cushion only decelerates; neither holds position against external forces, so use an external guide or lock for load holding.
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 MBLCJ32X40-40S FAQ
At 0.5 MPa, the push force is 402 N and the pull force is 346 N. At 0.7 MPa, the push force increases to 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa. The operating pressure range is 0.15 to 1.0 MPa.
The rear stroke adjuster physically limits the piston's travel, allowing you to trim the 40 mm stroke down to a 0 mm minimum position. The adjustable air cushion is a separate screw-tunable valve that controls the exhaust flow at the end of the stroke to decelerate the piston. Neither the cushion nor the stopper acts as a mechanical lock to hold the load in place without continuous air pressure.
