About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X40-40
The AirTAC MBLCJ32X40-40 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 push and 346 N pull force at 0.5 MPa. The rear stopper allows you to trim up to 40 mm of travel, creating a usable 0 to 40 mm stroke window for precise positioning. Unlike the fixed rubber bumper on an MBLJ, the screw-tunable cushion lets you dial in end-of-stroke deceleration for heavier moving loads, protecting the end covers from impact.
This SKU uses a Ø12 mm carbon-steel rod with 20 µm hard-chrome plating and a G1/8 port. It lacks a built-in magnet, meaning it cannot accept a CMSG, DMSG, or EMSG position sensor. The riveted rolling-packed barrel and heterogeneous two-way grease-retaining piston seal keep it compact and durable in tight spaces. Remember that the rear adjuster is a travel stop, not a load lock; the cushion only decelerates, so external guides are needed to hold a load in place.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X40-40 Is Used
PCB Router Spindle
Lifts a high-speed PCB routing spindle with 402 N of force, using the 0-40 mm stroke trim to set the exact Z-axis cutting depth and the air cushion to stop the rapid descent smoothly.
Bottle Capper Heads
Applies exactly 346 N of pull force to torque bottle caps, relying on the adjustable stroke window to accommodate varying container heights without changing the entire actuator setup.
Small Parts Ejector
Kicks finished machined aluminum parts out of a CNC lathe, using the tunable cushion to absorb the shock of the 0-40 mm stroke end and prevent end-cover damage during high-speed ejection.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X40-40 the Right Cylinder?
If you need less force, the 25 mm bore provides 245 N push at 0.5 MPa, while stepping up to the 40 mm bore yields 628 N. Choose this MBLCJ model over the MBLJ when your application requires tunable end-of-stroke deceleration rather than a fixed bumper, or over the MBLC when you need that rear travel stopper to trim the 0-40 mm window. Neither the cushion nor the stopper acts as a brake or lock, so live air is required to hold position. Mounting is limited to Basic, FA (flange), or LB (foot) brackets; no SDB pivot or back-cover options exist. For a direct replacement, match the 32 mm bore, 40 mm stroke, 40 mm adjust code, G1/8 PT thread, and confirm no magnet is fitted.
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 MBLCJ32X40-40 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 increases to 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa.
The rear stroke adjuster is a mechanical travel stop that trims the usable stroke window down to 0-40 mm. The adjustable air cushion is a screw-tunable valve that controls end-of-stroke deceleration. Neither holds the load in place; they only set the end point and slow the speed.
