About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X175-100
The AirTAC MBLCJ40X175-100 is a compact double-acting aluminum mini cylinder featuring a rear adjustable stroke and a tunable air cushion at both ends. It delivers 628 N of push force and 528 N of pull force at 0.5 MPa. The 100 mm rear adjuster creates a usable stroke window of 75 to 175 mm, allowing you to dial in the exact travel distance for a 40 mm bore application.
This model uses a G1/4 port, a Ø16 carbon-steel rod with 20 µm hard-chrome plating, and an M12x1.25 rod-end thread. The riveted rolling-packed barrel and grease-retaining piston seal keep contamination out in harsh environments. The adjustable air cushion lets you screw-tune end-of-stroke deceleration to protect the covers during heavier moves, while the rear stopper sets the travel end—neither component locks the load in place. Note that this specific SKU lacks a built-in magnet, meaning it cannot accept CMSG, DMSG, or EMSG position sensors.

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 MBLCJ40X175-100 Is Used
Pallet Diversion
With 628 N of push force at 0.5 MPa, this cylinder drives diverter arms on packaging lines, using the 75-175 mm stroke window to fine-tune the arm reach for varying pallet widths.
Press Fit Stations
The tunable air cushion smoothly decelerates the 880 N push force at 0.7 MPa when seating bearings or bushings into housings, preventing impact damage to the end covers.
Flying Cutoff Saws
A 175 mm stroke moves the saw carriage for dynamic tube cutting, while the rear stopper sets the precise cut depth without relying on a separate mechanical lock.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X175-100 the Right Cylinder?
If you need less force, step down to the 32 mm bore (402 N push at 0.5 MPa); if you need more, step up to the 50 mm bore (981 N push). Choose this MBLCJ over the MBLJ when you need tunable end-deceleration instead of a fixed rubber bumper, or over the MBLC when you require the 75-175 mm rear travel adjustment. Because the rear stopper only sets the travel end and the cushion only decelerates, you must use an external lock or guide rail to hold a load in place. Mounting is limited to Basic, FA, or LB; there is no SDB or back-cover option. To replace this cylinder exactly, match the 40 mm bore, 175 mm stroke, 100 mm adjust code, 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 MBLCJ40X175-100 FAQ
At 0.5 MPa, it provides 628 N push and 528 N pull. At 0.7 MPa, the push increases to 880 N, with a maximum theoretical output of 128 kgf at 1.0 MPa. The 100 mm rear adjuster creates a usable stroke window of 75 to 175 mm.
No. This specific SKU lacks the -S code for a built-in magnet, so it cannot accept AirTAC CMSG, DMSG, or EMSG sensor switches. You would need the MBLCJ40X175-100S variant for electronic position detection.
