About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X150-100S
The AirTAC MBLCJ25X150-100S is a compact double-acting aluminum 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 100 mm adjustment code allows you to trim the rear travel, creating a usable stroke window of 50 to 150 mm. This makes it highly effective for applications where a fixed 150 mm stroke is too long and would risk internal impact damage.
Unlike the base MBLJ which relies on a fixed rubber bumper, this MBLCJ variant uses screw-tunable deceleration to absorb kinetic energy at the stroke ends, protecting the end covers during faster or heavier moves. The -S code indicates a built-in magnet for position detection with CMSG reed or DMSG and EMSG solid-state switches. The riveted rolling-packed barrel and 20 µm hard-chrome plated carbon-steel rod handle speeds up to 800 mm/s. Remember, the rear stopper sets the travel end; it does not hold the load in place.

| 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 MBLCJ25X150-100S Is Used
PCB Conveyor Diverter
Tunes the 50-150 mm stroke window to push routing gates on a PCB conveyor, using the adjustable cushion to halt the 245 N push force softly without jarring delicate board edges.
Textile Tension Arm
Trims the rear stopper to set exact fabric guide arm positions in a textile machine, relying on the cushion needle to decelerate the rod smoothly at high cycling speeds.
Packaging Flap Folder
Folds cardboard flaps on a packaging line where the 206 N pull force secures the arm, and the built-in magnet triggers a DMSG sensor to confirm the fold completed.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X150-100S the Right Cylinder?
Selecting this bore depends on your force and space requirements. If you need less force, stepping down to the 20 mm bore yields 157 N push at 0.5 MPa, while stepping up to the 32 mm bore provides 402 N push. Choose the MBLCJ over the MBLJ when your cycle speed demands tunable end-cushioning rather than a fixed bumper, or over the MBLC when you need to trim the stroke length on the machine. The usable window here is 50-150 mm.
Neither the rear travel stopper nor the cushion needle acts as a lock; the rod drifts without live air, so use an external guide for side-load stability on this 150 mm stroke. Mounting is limited to Basic, FA, or LB; there is no SDB pivot or back-cover option. For a direct replacement, match the 25 mm bore, 150 mm stroke, 100 mm adjust code, G1/8 port, PT thread, and the -S magnet. The overall length equals A + 2 x stroke + adjust.
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 MBLCJ25X150-100S FAQ
At 0.5 MPa, this 25 mm bore cylinder provides 245 N of push force and 206 N of pull force. At 0.7 MPa, the push force increases to 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa.
The 100 mm adjustable stroke is a rear travel stopper that limits the rod's end position, giving you a usable 50-150 mm window. The adjustable air cushion is a separate screw that tunes end-of-stroke deceleration to protect the covers. Neither mechanism locks the load; the rod drifts without air pressure.
