About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X200-75S
The AirTAC MBLCJ25X200-75S is a compact double-acting mini cylinder featuring a rear stroke adjuster and tunable air cushions at both ends. It delivers 245 N of push force and 206 N of pull force at 0.5 MPa. The 75 mm rear adjuster allows you to trim the travel down, providing a usable stroke window of 125 to 200 mm. This flexibility is ideal for applications requiring exact end-position tuning without swapping the entire actuator.
Unlike the standard MBLJ which relies on a fixed rubber bumper, this model uses screw-tunable adjustable air cushions to decelerate the rod at the stroke extremes, absorbing kinetic energy to protect the end covers. The riveted aluminum barrel and 20 um hard-chrome plated carbon-steel rod ensure durability, while the built-in magnet (-S) enables position detection. Note that the rear adjuster acts as a mechanical travel stop, not a lock; it sets the end point but cannot hold a load under pressure without live air.

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 (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 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 MBLCJ25X200-75S Is Used
PCB Drill Depth Setter
Uses the 125-200 mm adjustable window to precisely set the Z-axis travel limit for a drill head, while the air cushion prevents bounce at the bottom of the 245 N stroke.
Textile Loom Tension Arm
Tunes the rear stopper to regulate fabric take-up tension over a long 200 mm pull, relying on the magnet for end-of-travel signaling to the loom controller.
Packaging Flap Folder
Folds heavy cardboard flaps at high cycle rates, using the adjustable air cushion to decelerate the 206 N pull force smoothly without slamming the cylinder end covers.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X200-75S the Right Cylinder?
When sizing this 25 mm bore actuator, consider stepping down to the 20 mm version if your load requires only 157 N of push force at 0.5 MPa, or stepping up to the 32 mm bore for a substantial increase to 402 N. The MBLCJ25X200-75S is specified by its 25 mm bore, 200 mm stroke, 75 mm adjustment code, G1/8 port, PT thread form, and built-in magnet. Mounting is limited to Basic, FA (flange), or LB (foot) styles, as this series does not support SDB pivots or back-cover options. Because the total stroke reaches 200 mm, the 10 mm rod is susceptible to side-loading; always use an external guide to prevent rod bending and premature seal wear. The adjustable air cushion tunes end-of-stroke deceleration, but neither the cushion nor the rear stopper will mechanically lock the load in place.
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 MBLCJ25X200-75S 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 75 mm rear adjuster physically stops the rod early, creating a usable travel window of 125 to 200 mm. The adjustable air cushion is a separate screw-tunable feature that decelerates the piston at the end of its travel to prevent impact damage; neither feature locks or holds the load.
