About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X175-100S
The AirTAC MBLCJ40X175-100S is a compact double-acting mini cylinder featuring a rear travel stopper that creates a 75-175 mm usable stroke window, trimming up to 100 mm off the nominal 175 mm extension. It delivers 628 N of push force at 0.5 MPa and incorporates a screw-tunable adjustable air cushion at both ends to decelerate heavier moving masses smoothly. This protects the aluminum end covers from impact damage that a standard fixed rubber bumper cannot absorb.
Built with a riveted rolling-packed aluminum barrel and a Ø16 mm carbon-steel rod plated with 20 µm hard chrome, it withstands harsh environments. The built-in magnet (-S) supports CMSG reed and DMSG or EMSG solid-state sensors for precise end-of-stroke detection. Remember, the rear stopper sets the travel endpoint and the cushion governs deceleration; neither component mechanically locks the load in place.

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)

| 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 MBLCJ40X175-100S Is Used
Spindle Feed Deceleration
Drives a machining center spindle head downward, using the 628 N push force and tunable cushion to halt the 175 mm descent smoothly without shocking the bearings.
Pallet Diverting Arm
Extends a routing gate on a packaging conveyor, relying on the 75-175 mm adjustable window to hit the exact pallet width without re-mounting hardware.
Component Pressing
Presses bearings into housings on an assembly line, using the DMSG solid-state sensor to verify press depth and the air cushion to prevent snap-back rebound.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X175-100S the Right Cylinder?
For lower force needs, stepping down to the 32 mm bore yields 402 N push at 0.5 MPa, whereas moving up to the 50 mm bore provides 981 N for heavier payloads. Choose this MBLCJ variant over the MBLJ when your application speed requires tunable end-cushioning rather than a fixed bumper, or over the MBLC if you need to fine-tune the end position within that 75-175 mm window.
The rear adjuster and the cushion needle are travel stops and deceleration devices, not brakes; use an external locking mechanism if the load must hold position without live air. Mounting is limited to Basic, FA flange, or LB foot styles—no SDB pivot or back-cover options exist. To replace this unit exactly, match the 40 mm bore, 175 mm stroke, 100 mm adjust code, G1/4 port, PT thread, and the -S magnet specification.
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 MBLCJ40X175-100S FAQ
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, the push force increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa.
The 100 mm adjustable stroke is a rear mechanical stopper that limits the usable travel to a 75-175 mm window. The adjustable air cushion only tunes deceleration at the stroke ends. Neither holds the load; the cushion is not a lock.
