About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X25-20
The AirTAC MBLCJ32X25-20 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster 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 stopper allows you to trim up to 20 mm of travel, creating a highly precise 5 to 25 mm usable stroke window for short-stroke clamping or positioning tasks.
Unlike the fixed rubber bumper found on the base MBLJ series, the screw-tunable air cushions on this unit decelerate the piston near the end caps, absorbing kinetic energy to prevent end-cover damage during faster actuation. The riveted rolling-packed barrel and 20 µm hard-chrome plated carbon-steel rod ensure durability. Because this specific SKU lacks the -S suffix, it has no built-in magnet and cannot support CMSG, DMSG, or EMSG position sensors.

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 MBLCJ32X25-20 Is Used
PCB Edge Routing Damping
Deploys the 5-25 mm adjusted stroke to press router guides against printed circuit boards, using the 402 N thrust and tunable air cushion to absorb vibration without cracking the substrate.
Bottle Capper Height Trim
Adjusts the 25 mm travel down to a 5 mm window for capping varied container heights on a filling line, relying on the rear stopper to set the exact cap seating depth.
Textile Loom Tensioner
Cycles rapidly to maintain yarn tension, where the adjustable end cushions absorb the kinetic energy of the 346 N pull force, preventing premature wear on the aluminum end covers.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X25-20 the Right Cylinder?
For lower force requirements, stepping down to a 25 mm bore yields 245 N of push force at 0.5 MPa, while stepping up to a 40 mm bore provides 628 N if your payload demands more thrust. Choose the MBLCJ over the MBLJ when your cycle speed requires tunable end-of-stroke deceleration rather than a fixed bumper, or over the MBLC when you need that rear travel stopper to fine-tune the end position. Remember that the rear adjuster is a travel stop, not a lock; the cushion only decelerates. Neither will hold a load in place without live air pressure, so external locking mechanisms are required for absolute position holding.
This configuration uses a G1/8 port with PT (tapered) threading, a Ø12 mm rod with an M10x1.25 rod-end thread, and Basic/FA/LB mounting options (no SDB or back-cover variants are available). The overall length extends by the adjustment dimension (A + 2 x stroke + adjust). When replacing this part, match the 32 mm bore, 25 mm nominal stroke, 20 mm adjust code, PT thread, and confirm no magnet is required.
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 MBLCJ32X25-20 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, with a maximum theoretical output of 82 kgf at 1.0 MPa. The rear adjuster is a travel stop and the air cushion only decelerates motion; neither acts as a lock, so the rod will drift if air pressure is lost.
No. Because this specific SKU lacks the -S suffix, it is manufactured without a built-in piston magnet. It cannot be used with AirTAC CMSG (reed), DMSG, or EMSG (electronic) sensor switches. If position detection is required, you must select the MBLCJ32X25-20S variant.
