About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X175-10
The AirTAC MBLCJ40X175-10 is a compact double-acting mini cylinder featuring a rear travel stopper that creates a 165 to 175 mm usable stroke window. It delivers 628 N of push force and 528 N of pull force at 0.5 MPa. A screw-tunable air cushion at both ends absorbs end-of-stroke kinetic energy, protecting the end covers from impact damage better than a fixed rubber bumper.
This 40 mm bore unit uses a G1/4 port and a Ø16 carbon-steel rod with 20 µm hard-chrome plating to resist corrosion and seal wear. Because this SKU lacks the -S magnet suffix, it cannot host a CMSG, DMSG, or EMSG position sensor. The riveted aluminum barrel keeps the body lightweight for tight machine spaces.

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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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 MBLCJ40X175-10 Is Used
Textile Loom Beat-Up
Drives the loom reed forward with 628 N at 0.5 MPa, using the adjustable air cushion to soften the 175 mm stroke end and prevent yarn breakage.
Bottling Line Diverter
Actuates a routing gate at 800 mm/s, relying on the 10 mm rear stopper to trim the exact handoff position without needing a mechanical hard-stop.
Printed Circuit Board Loader
Pushes PCB magazines into a testing fixture, where the tunable end cushions absorb the magazine mass to protect delicate edge connectors.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X175-10 the Right Cylinder?
If you need less force, the 32 mm bore yields 402 N push at 0.5 MPa; for heavier loads, the 50 mm bore provides 981 N. Choose this MBLCJ over the MBLJ when your moving mass requires tunable pneumatic deceleration instead of a fixed bumper, or over the MBLC if you need to fine-tune the end position by up to 10 mm. Remember the rear adjuster is a travel stop, not a lock, and the cushion only decelerates, so an external guide or lock is required to hold a load. Mounting is limited to Basic, FA, or LB; no SDB or back-cover options exist. To match this replacement exactly, use bore 40, stroke 175, adjust 10, G1/4 port, PT thread, and no magnet.
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 MBLCJ40X175-10 FAQ
At 0.5 MPa it provides 628 N push and 528 N pull. At 0.7 MPa the push force is 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa.
No, this specific SKU lacks the built-in magnet, so it cannot host CMSG reed or DMSG/EMSG electronic sensors. You would need the -S suffix version for position detection.
