About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X225-40S
The AirTAC MBLCJ25X225-40S 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 40 mm rear stopper trims the travel end, creating a usable stroke window of 185 to 225 mm for exact endpoint positioning. A built-in magnet (-S) enables CMSG, DMSG, or EMSG sensor switches to track rod position.
Unlike the fixed rubber bumper on the base MBLJ, the screw-tunable cushion valves on this SKU decelerate heavier loads near the stroke ends, protecting the aluminum end covers. The riveted rolling-packed barrel and 20 um hard-chrome plated carbon-steel rod withstand demanding cycles. Remember the rear stopper sets the travel limit; it does not lock the load in place, and the cushion only controls speed.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X225-40S Is Used
PCB Router Z-Axis
Drives a 245 N routing head up and down, using the 185-225 mm adjustable window to set exact cutter clearance and relying on the air cushion to prevent hard end-impacts during rapid retraction.
Dispensing Valve Positioning
Actuates a fluid dispensing nozzle over a 225 mm reach, using the CMSG reed sensor to trigger the valve open exactly when the cushioned stroke reaches the lower trim limit.
Textile Fabric Guide
Shifts a fabric spreader across a 225 mm web path, tuning the cushion to gently decelerate the 206 N pull force and prevent tension snags at the end of travel.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X225-40S the Right Cylinder?
For lower force needs, stepping down to a 20 mm bore yields 157 N push at 0.5 MPa, while moving up to a 32 mm bore provides 402 N. Choose this MBLCJ over the MBLJ when your application speed requires tunable end-of-stroke deceleration rather than a fixed bumper. The overall length equals A + 2 x stroke + adjust, so plan your envelope accordingly.
Mounting is limited to Basic, FA (flange), or LB (foot) as there is no back-cover or SDB pivot option. The replacement match is a 25 mm bore, 225 mm stroke, 40 mm adjust, G1/8 port, PT thread, with a magnet. Because the stroke is 225 mm, the 10 mm rod is susceptible to bending under lateral stress; always use an external guide to prevent side-load 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 MBLCJ25X225-40S 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 is 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa operating pressure.
The 40 mm rear adjuster acts as a mechanical travel stop, allowing you to set a usable stroke window between 185 mm and 225 mm. The adjustable air cushion is a separate screw-tunable valve that controls end-of-stroke deceleration. Neither the cushion nor the stopper acts as a lock to hold the load in place.
