About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X80-20S
The AirTAC MBLCJ32X80-20S is a compact, double-acting aluminum mini cylinder engineered for precise motion control. It features a rear stroke adjuster allowing you to trim up to 20 mm of travel, creating a usable 60-80 mm stroke window. Paired with a tunable air cushion at both ends, it provides smooth deceleration for moving loads. Delivering 402 N of push force at 0.5 MPa, it is built with a riveted rolling-packed barrel and a 20 µm hard-chrome plated carbon-steel rod for rugged, leak-free performance.
This model includes a built-in magnet (-S) for compatibility with AirTAC CMSG reed and DMSG or EMSG solid-state sensor switches. The adjustable air cushion lets you dial in end-of-stroke deceleration to protect components during faster cycles, while the rear stopper sets the exact end position. Remember that the cushion only decelerates and the stopper only sets travel; neither acts as a mechanical lock to hold a load in place without live air pressure.

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 MBLCJ32X80-20S Is Used
PCB Router Z-Axis
Lifts and lowers a spindle router on a PCB depaneling machine. The 60-80 mm stroke window sets the exact cutting depth, while the air cushion prevents a jarring impact at the top of the travel, protecting the precision spindle bearings.
Textile Tensioner
Acts as a dynamic yarn tensioning arm on a weaving loom. The 402 N push force at 0.5 MPa maintains steady tension against the thread beam, and the rear adjuster allows operators to dial in the exact slack take-up distance without changing hardware.
Bottle Capper Head
Drives the spin-on capping head onto plastic beverage bottles. The adjustable cushion screws let operators tune the downstroke deceleration so the cap tightens firmly without shattering the plastic threads.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X80-20S the Right Cylinder?
Choosing this 32 mm bore depends on your force and space requirements. If you need less force, the 25 mm bore offers 245 N of push at 0.5 MPa; if your application demands more power, stepping up to the 40 mm bore yields 628 N. This MBLCJ variant is preferred over the MBLJ when your moving mass requires tunable pneumatic damping instead of a fixed rubber bumper, and over the MBLC when you need that cushioning combined with a shorter, adjustable overall length. To match this exact replacement, confirm the 32 mm bore, 80 mm stroke, 20 mm adjust code, G1/8 port, PT thread, basic mounting, and the -S magnet.
Mounting is limited to Basic, FA flange, or LB foot styles; this series does not support SDB pivot or back-cover configurations. Because the overall length equals the base plus twice the stroke plus the 20 mm adjuster, verify your spatial envelope. For any stroke approaching 300 mm or beyond, the 12 mm rod becomes susceptible to bending, so an external guide rail is required to prevent side-load damage.
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 MBLCJ32X80-20S FAQ
At 0.5 MPa, this 32 mm bore double-acting cylinder provides 402 N of push force and 346 N of pull force. At 0.7 MPa, the push force increases to 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa.
The rear adjustable stroke is a mechanical travel stop that lets you trim the end position by up to 20 mm, creating a 60-80 mm usable window. The adjustable air cushion is a screw-tunable valve that controls end-of-stroke deceleration. Neither holds a load in place without continuous air pressure; they only set travel limits and slow the piston.
