About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X200-30S
The AirTAC MBLCJ25X200-30S is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and a tunable 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 30 mm of travel, creating a usable stroke window of 170 to 200 mm to dial in exact end positions. A built-in magnet enables position detection with CMSG reed or DMSG and EMSG solid-state switches.
This model uses a G1/8 port and a Ø10 mm hard-chrome plated carbon-steel rod. The riveted aluminum barrel and grease-retaining piston seal ensure reliable service in tight spaces. The adjustable air cushioning protects the end covers by decelerating heavier or faster 200 mm moves, while the two-way seal design maintains consistent pressure separation. The rear adjuster acts purely as a mechanical travel stop and does not lock or hold 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 (Ø25mm)

|---|---|---|
| 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 MBLCJ25X200-30S Is Used
PCB Router Z-Axis
Lifts and lowers a spindle on a PCB depaneling router, using the 170-200 mm window to set exact cutting depth while the air cushion prevents hard stops at high speed.
Textile Tension Arm
Acts as a dancer arm in a textile winding machine, trimming 30 mm of travel to balance fabric tension, with cushioning absorbing the shock of rapid direction changes.
Small Parts Ejector
Pushes molded plastic parts out of an injection mold cavity, using 245 N of force and the tunable cushion to prevent the component from launching at the end of the 200 mm stroke.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X200-30S the Right Cylinder?
Stepping down to the 20 mm bore drops the output to 157 N push at 0.5 MPa, whereas moving up to the 32 mm bore increases thrust to 402 N. Choose this 25 mm bore when your application requires around 245 N of push force. The MBLCJ is preferred over the MBLJ when you need screw-tunable end-of-stroke deceleration instead of a fixed rubber bumper, and it offers rear travel trimming that the fixed-stroke MBLC lacks.
Remember that neither the rear stroke adjuster nor the air cushion acts as a load-holding brake; you need live air or an external lock for position holding. Mounting is limited to Basic, FA flange, or LB foot styles, as there is no SDB pivot or back-cover option. For an exact replacement, match the 25 mm bore, 200 mm stroke, 30 mm adjust code, G1/8 PT threaded port, and the -S magnet specification. Because the stroke is 200 mm on a 10 mm rod, use an external guide to prevent side-load bending.
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 MBLCJ25X200-30S FAQ
At 0.5 MPa it provides 245 N push and 206 N pull force. At 0.7 MPa the push force is 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa, with an operating pressure range of 0.15 to 1.0 MPa.
The rear adjustable stroke is a mechanical travel stop that lets you trim the end position within a 170 to 200 mm window, but it does not hold the load. The adjustable air cushion is a screw-tunable valve that bleeds trapped air to decelerate the piston near the end covers, which is not a locking mechanism either.
