About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X40-10S
The AirTAC MBLCJ32X40-10S is a compact double-acting mini cylinder featuring a riveted aluminum barrel and a single rod. It delivers 402 N of push force at 0.5 MPa. A rear stopper allows you to trim up to 10 mm of travel, creating a usable 30-40 mm stroke window for precise positioning. The integrated -S magnet enables position detection via CMSG reed or DMSG/EMSG electronic switches.
Unlike the base MBLJ which relies on a fixed rubber bumper, this MBLCJ variant incorporates a screw-tunable adjustable air cushion at both ends to decelerate the rod gently. The 20 µm hard-chrome plated carbon-steel rod resists wear, while the heterogeneous two-way grease-retaining piston seal maintains lubrication over high-speed 30-800 mm/s cycles. The rear adjuster is strictly a travel stop, not a load lock.

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 MBLCJ32X40-10S Is Used
PCB Router Z-Axis
Drives a spindle downstroke on a desktop PCB milling machine, using the 30-40 mm stroke window to fine-tune the cutting depth limit and the air cushion to prevent hard mechanical stops during fast 30-800 mm/s traversals.
Bottle Capper Head
Applies 402 N of downward force to press plastic caps onto beverage bottles, tuning the rear stopper to compensate for varying cap heights while the cushion absorbs the deceleration of the 12 mm rod at stroke end.
Vision System Ejector
Uses the built-in magnet with a DMSG solid-state sensor to trigger a reject arm that pushes faulty surface-mount components off a conveyor belt, relying on the 346 N pull force to retract the mechanism rapidly.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X40-10S the Right Cylinder?
For lower force needs, stepping down to the 25 mm bore yields 245 N push at 0.5 MPa, whereas moving up to the 40 mm bore provides 628 N. Choose this MBLCJ over the MBLJ when your payload or cycle speed demands tunable end-cover protection rather than a fixed bumper, or over the MBLC if your machine timing requires a 30-40 mm adjustable end-position rather than a fixed 40 mm stroke. The rear stroke adjuster and the air cushion regulate travel and deceleration respectively, but neither will hold a suspended load in place without live air pressure.
Mounting is limited to Basic, FA flange, or LB foot brackets, as there is no SDB pivot or back-cover option. Overall length equals A + 2 x stroke + adjust. To replace this exact unit, match the 32 mm bore, 40 mm stroke, 10 mm adjust code, G1/8 PT port, M10x1.25 rod-end thread, and the -S magnet specification.
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 MBLCJ32X40-10S FAQ
At 0.5 MPa it provides 402 N push and 346 N pull force, increasing to 563 N push at 0.7 MPa, with a theoretical maximum of 82 kgf at 1.0 MPa. The fluid port is G1/8 and the rod-end thread is M10x1.25.
The 10 mm adjustable stroke is a rear mechanical stopper that sets the end-of-travel position within a 30-40 mm window, whereas the adjustable air cushion is a needle valve that controls exhaust flow to decelerate the piston near the covers. Neither mechanism locks the load; you need external pneumatics or a mechanical brake to hold a position.
