About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X350-20
The AirTAC MBLCJ32X350-20 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 adjustment allows you to trim up to 20 mm of travel, creating a usable stroke window from 330 to 350 mm to fine-tune end positions.
Unlike the standard MBLJ which relies on a fixed rubber bumper, this model uses screw-tunable air cushioning to decelerate heavier loads smoothly at the stroke extremes, protecting the end covers. The riveted rolling-packed barrel and 20 um hard-chrome plated carbon-steel rod withstand harsh environments. Note that this specific SKU lacks a built-in magnet (-S), meaning it cannot support CMSG, DMSG, or EMSG position sensors.

| 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 MBLCJ32X350-20 Is Used
Textile Loom Beater
Drives the 350 mm reed motion in a textile loom, using the 330-350 mm window to time the fabric beat precisely while the air cushion absorbs the high cyclic impact.
Conveyor Diverter Gate
Actuates a sorting flap on a packaging line, relying on the 402 N push force to overcome spring tension and the tunable cushion to prevent hard slamming at 800 mm/s.
CNC Chip Auger
Extends a 350 mm chip clearing auger in a CNC machine, where the adjustable stopper dials in the exact ejection position without requiring custom machined spacers.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X350-20 the Right Cylinder?
If you need less force, the 25 mm bore offers 245 N push at 0.5 MPa; if your application requires more thrust, step up to the 40 mm bore which provides 628 N. Choose this MBLCJ over the MBLJ when your moving mass requires tunable end-of-stroke deceleration rather than a fixed rubber bumper, or over the MBLC when you need to trim the travel end. Remember the rear stopper sets the travel limit and the cushion only decelerates; neither holds the load in place, so use an external lock for position holding. Mounting is limited to Basic, FA, or LB (no SDB or back-cover options). For an exact replacement, match the 32 mm bore, 350 mm stroke, 20 mm adjust code, G1/8 PT thread, and no-magnet configuration. Because the 350 mm stroke approaches the 500 mm maximum for this bore, the 12 mm rod is highly susceptible to side-load bending; always guide the load externally.
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 MBLCJ32X350-20 FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N push and 346 N pull force. At 0.7 MPa, the push force is 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
The rear adjustable stroke is a mechanical travel stop that lets you trim the usable stroke from 330 to 350 mm. The adjustable air cushion is a screw-tunable valve that controls deceleration at the stroke ends. Neither feature locks or holds the load; they only set travel limits and speed.
