About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X350-40S
The AirTAC MBLCJ32X350-40S 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 at 0.5 MPa through a 12 mm hard-chrome plated rod. The 40 mm rear trimmer creates a usable travel window of 310 to 350 mm, letting you dial in the exact end position without machining spacers.
Unlike the fixed rubber bumper found on the base MBLJ, this model uses screw-tunable air cushions to decelerate heavy loads before impact, protecting the end covers during fast cycles. The riveted rolling-packed barrel and grease-retaining piston seal ensure consistent friction. A built-in magnet (-S) enables position detection, while the 350 mm stroke on a 12 mm rod necessitates an external guide to prevent side-load bending.

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 MBLCJ32X350-40S Is Used
Textile Loom Weft Insertion
Uses the 310-350 mm adjustable stroke window to precisely time the weft insertion guide, while the air cushions absorb the rapid deceleration of the 346 N pull force at high cycling speeds.
Packaging Carton Diverter
Pushes corrugated cartons on a sorting line with 402 N of force, relying on the tunable cushion to prevent harsh slams that could damage board edges during rapid 350 mm extensions.
PCB Test Fixture Actuation
Moves a flying probe test head across a 350 mm span, using the -S magnet with a DMSG electronic sensor to confirm the exact 310 mm retracted position before firing test pins.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X350-40S the Right Cylinder?
For lower force needs, stepping down to the 25 mm bore yields 245 N push at 0.5 MPa, whereas stepping up to the 40 mm bore provides 628 N. Choose this MBLCJ over an MBLJ when your moving mass requires tunable end-of-stroke deceleration rather than a simple bumper, or over an MBLC if you need the 40 mm rear travel adjustment. The rear stopper sets the travel end but does not hold the load, and the cushion only decelerates; neither acts as a lock.
Mounting is limited to Basic, FA (flange), or LB (foot) as there is no back-cover or SDB pivot option. The 350 mm stroke on a 12 mm rod creates a high slenderness ratio, so an external guide is mandatory to prevent rod bending. The exact replacement match is: 32 mm bore, 350 mm stroke, 40 mm adjust code, G1/8 port, PT thread, basic mounting, with a built-in magnet for CMSG, DMSG, or EMSG sensors.
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 MBLCJ32X350-40S 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. The maximum theoretical force is 82 kgf at the 1.0 MPa operating pressure limit.
The 40 mm rear adjuster is a mechanical travel stop that sets your usable stroke window between 310 and 350 mm. The adjustable air cushion is a separate screw-tunable valve that regulates exhaust flow to decelerate the piston near the end covers. Neither feature locks or holds the load in place.
