About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X175-100S
The AirTAC MBLCJ25X175-100S is a compact double-acting mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. It delivers 245 N of push force and 206 N of pull force at 0.5 MPa. The rear stopper allows you to trim up to 100 mm of travel, creating a usable stroke window of 75 to 175 mm. This specific tuning is ideal for varying pick-and-place heights without swapping the entire actuator.
Unlike the standard MBLJ which relies on a fixed rubber bumper, this model uses screw-tunable end-of-stroke cushioning to decelerate heavier loads smoothly and protect the end covers. The riveted aluminum barrel and 20 µm hard-chrome plated carbon-steel rod withstand demanding cycles. Because the -S code is present, a built-in magnet enables position detection via AirTAC CMSG (reed), DMSG, or EMSG (solid-state) sensor switches. The adjuster acts strictly as a travel stop and the cushion only decelerates; neither will mechanically lock or hold a load in place without continuous air pressure.

| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | — |
| Max (@1.0 MPa) | 50 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 MBLCJ25X175-100S Is Used
PCB Router Z-Axis
Adjusts the cutting depth on a printed circuit board routing spindle. The 75-175 mm window allows tool changes and height compensation, while the air cushion absorbs the rapid tool lift without shocking the Z-axis linear rails.
Variable Depth Dispensing
Actuates a syringe dispense head in an electronics potting line. The 100 mm rear trim accommodates different potting well depths, and the magnet triggers an EMSG solid-state switch for precise fill-volume positioning.
Textile Yend Guide
Tensions and guides yarn threads on a weaving loom. The 245 N push force at 0.5 MPa maintains proper tension, while the tunable cushion prevents the guide carriage from snapping the thread at the stroke end.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X175-100S the Right Cylinder?
If 245 N at 0.5 MPa is too much force, step down to the Ø20 bore which provides 157 N of push force. If your application requires more thrust, step up to the Ø32 bore which provides 402 N. Choose this MBLCJ variant over the fixed-stroke MBLC when you need on-the-fly travel adjustments, and over the fixed-bumper MBLJ when your cycle speeds demand tunable deceleration. Remember that the rear adjuster sets the travel end, while the cushion tunes deceleration—neither functions as a lock to hold a load against drift.
For a drop-in replacement, match the 25 mm bore, 175 mm stroke, 100 mm adjust code, G1/8 port, PT thread form, and the -S magnet. Mounting is limited to Basic, FA (flange), or LB (foot) options; no back-cover or SDB pivot configurations are available. At 175 mm of travel, the Ø10 mm rod is susceptible to side-load bending—always use an external guide rail to support the payload and prevent cylinder damage.
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 MBLCJ25X175-100S FAQ
At 0.5 MPa, the push force is 245 N and the pull force is 206 N. At 0.7 MPa, the push force increases to 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa.
The rear stroke adjuster physically stops the piston to set your travel end within the 75 to 175 mm window, but it does not lock or hold the load in place. The adjustable air cushion uses a needle screw to tune end-of-stroke deceleration, absorbing kinetic energy to protect the end covers.
