About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X75-40
The AirTAC MBLCJ32X75-40 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and tunable air cushioning at both ends. It delivers 402 N push force at 0.5 MPa via a Ø12 mm hard-chrome plated carbon-steel rod. The 40 mm adjustment code lets you mechanically trim the rear travel stopper, creating a usable end-position window of 35 to 75 mm for exacting machinery setups.
Unlike the fixed rubber bumper found on the base MBLJ, the screw-tunable end cushions here decelerate heavier 32 mm bore loads to protect the end covers during rapid 30-800 mm/s cycles. The riveted rolling-packed aluminum barrel and two-way grease-retaining piston seal ensure stable friction. This specific SKU lacks the -S magnet, meaning it cannot accept CMSG reed or DMSG electronic position sensors.

| Model | Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X75-40 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (adjustable stroke) |
| Bore size | Ø32 mm |
| Nominal stroke | 75 mm |
| Adjustable window | 35–75 mm (trim 40 mm) |
| Acting type | Double acting |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Adjustable air cushion (both ends) |
| Max standard stroke | Up to 500 mm |
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 MBLCJ32X75-40 Is Used
PCB Depaneling Saw Feed
Uses the 35-75 mm stroke window to set the exact cutting depth on a circular saw blade, relying on the tuned air cushion to prevent bounce-back at the end of the 402 N feed push.
Bottle Capper Torque Head
Adjusts the downward travel stopper to compensate for varying cap heights on a packaging line, while the 346 N retraction force lifts the capping head smoothly without slamming.
Textile Loom Tensioner
Trims the yarn-guide arm position within the 35-75 mm range, using the 32 mm bore's 563 N push at 0.7 MPa to maintain consistent fabric tension during high-speed weaving.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X75-40 the Right Cylinder?
When sizing this 32 mm bore actuator, stepping down to the 25 mm version yields 245 N push at 0.5 MPa, while stepping up to the 40 mm bore provides 628 N for heavier payloads. Choose this MBLCJ over the MBLJ when your dynamic loads need active deceleration rather than a passive bumper, or the MBLC if your travel distance is permanently fixed. The rear adjuster sets a physical travel limit and the cushion only decelerates; neither component locks or holds the load—use an external locking mechanism for position holding. Mounting is limited to Basic, FA flange, or LB foot styles (no SDB pivot or back-cover options). To match this exact replacement: 32 mm bore, 75 mm stroke, 40 mm adjust code, G1/8 port, PT thread, no 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 MBLCJ32X75-40 FAQ
This 32 mm bore double-acting cylinder delivers 402 N push and 346 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and a maximum theoretical output of 82 kgf at 1.0 MPa.
The 40 mm rear adjustment is a mechanical travel stopper that sets your usable stroke window (35 to 75 mm), whereas the adjustable air cushion only regulates deceleration speed at the cover ends. Neither holds the load in place; the adjuster stops movement and the cushion dampens impact.
