This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X175-10-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X175-10-S in place of this model. The MBLJ replacement upgrades to a riveted rolling-packed body and CMSG / DMSG / EMSG sensors (the MAL used CS1-M / DS1-M).
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-10-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-10-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 10 mm, giving a usable end-position window from 165 to 175 mm. This model is discontinued — the drop-in replacement is the MBLJ40X175-10-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-10-S
The AirTAC MALJ40X175-10-S is a discontinued double-acting, single-rod mini cylinder with a 40 mm bore and 175 mm stroke. A rear screw stopper lets you trim up to 10 mm, giving a usable end-position window of 165-175 mm. It delivers 628 N push and 528 N pull at 0.5 MPa. The exact drop-in replacement is the MBLJ40X175-10-S.
This adjustable stroke is a travel stop, not a lock; it sets the end position but will not hold a load without live air. The fixed rubber bumper softens end impact, but MALJ has no adjustable air cushion. Upgrading to the MBLJ40X175-10-S shifts you from threaded covers to a riveted rolling-packed body. The -S magnet on this MALJ works with older CS1-M / DS1-M switches, while the MBLJ replacement uses CMSG / DMSG / EMSG sensors.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-10-S Is Used
Printed Circuit Board Tester
Dial the 165-175 mm reach to seat test pins precisely without re-machining the fixture bracket.
Wire Harness Crimp Press
Fine-tune the 628 N stroke end to set crimp depth on varying terminal sizes without swapping cylinders.
Packaging Flap Folder
Adjust the end position by 10 mm to fold varying carton flap heights accurately on the fly.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-10-S with MBLJ40X175-10-S
To replace the MALJ40X175-10-S, order the exact drop-in MBLJ40X175-10-S. Confirm the 40 mm bore, 175 mm stroke, 10 mm adjust code, G1/4 port, and M12x1.25 rod-end thread. Mounting is FA or LB only (no back cover or SDB code). The -S magnet requires changing from CS1-M / DS1-M to CMSG / DMSG / EMSG switches. Remember the adjuster is a stop, not a lock.
For sizing, step down to the 32 mm bore (402 N push @0.5 MPa) if you need less force, or step up to a larger ISO cylinder if you need more. At 175 mm stroke, watch rod-bending under side loads; use a guide to prevent binding.
Upgrade checklist
- ✓ Order the MBLJ40X175-10-S (same bore/stroke/adjust)
- ✓ Same 165–175 mm adjustable window
- ✓ Adjuster is a stop, not a lock
- ✓ No back cover / SDB — plan an FA/LB mount
- ✓ Sensor: swap CS1-M/DS1-M → CMSG/DMSG/EMSG
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.1 – 1.0 MPa operating pressure.
- check The rear adjuster sets the end position — it is not a load lock.
- check No back-cover / SDB on adjustable-stroke — use FA / LB.
- check Front/rear covers are threaded — not for field disassembly.
- check For new builds, specify the MBLJ40X175-10-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-10-S FAQ
Yes, the MALJ40X175-10-S is discontinued. The exact drop-in replacement is the MBLJ40X175-10-S, which matches the 40 mm bore, 175 mm stroke, 10 mm adjust code, G1/4 port, and FA/LB mounting. The MBLJ shifts from threaded covers to a riveted rolling-packed body and updates the -S magnet from CS1-M / DS1-M to CMSG / DMSG / EMSG switches.
The 10 mm adjust code lets you trim the 175 mm stroke back to 165 mm, giving a usable window of 165-175 mm. The adjuster is a travel stop, not a lock. Force figures: push 628 N and pull 528 N at 0.5 MPa; push 880 N at 0.7 MPa; max 128 kgf at 1.0 MPa.
