About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X200-20
The AirTAC MBLCJ25X200-20 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 at 0.5 MPa. The rear stopper lets you trim up to 20 mm of travel, creating a usable stroke window of 180 to 200 mm for exact end-position tuning. A 200 mm stroke suits linear transfers and medium-range indexing tasks.
Unlike the fixed rubber bumper on an MBLJ, the screw-tunable air cushions on this unit allow precise end-of-stroke deceleration for faster cycling without slamming the end covers. The Ø10 mm carbon-steel rod features 20 µm hard-chrome plating to resist scoring, while the riveted rolling-packed barrel ensures structural integrity under fluctuating pressures. Because this specific SKU lacks the -S magnet code, it cannot accept a CMSG or DMSG position sensor. The rear adjuster acts purely as a travel stop and does not lock or hold the load in place.

| 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 MBLCJ25X200-20 Is Used
PCB Edge Router Feeding
Uses the 180-200 mm stroke window to push printed circuit boards into a routing station, relying on the 245 N push force and adjustable cushion to prevent impact bounce.
Small Parts Ejector
Tuned air cushions absorb the kinetic energy of ejecting plastic injection molded parts at high speed, protecting the end covers from repeated shock.
Label Applicator Platen
Provides a precise 200 mm extension to press an applicator pad against moving packaging, with the 20 mm rear adjuster allowing exact dwell positioning.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X200-20 the Right Cylinder?
Step down to the Ø20 bore if your load requires less than 157 N of push force at 0.5 MPa, or step up to the Ø32 bore (402 N push) for heavier payloads. Choose this MBLCJ over the MBLJ when your application moves fast enough to need tunable pneumatic cushioning rather than a fixed bumper, or over the MBLC when you need to fine-tune the end position. Note that the 200 mm stroke on a small Ø10 mm rod creates a high rod-to-length ratio; for any side-loading forces, you must use an external guide rail to prevent rod bending.
The exact replacement match requires a 25 mm bore, 200 mm stroke, 20 mm adjust code, G1/8 port, PT thread, and Basic mounting (no FA or LB code). Mounting is limited to Basic, FA, or LB foot brackets; there is no SDB pivot or back-cover option. Neither the rear travel stopper nor the adjustable cushion functions as a mechanical lock—use an external holding device if the load must resist drift when air is removed.
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 MBLCJ25X200-20 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.
This specific SKU lacks the -S code, meaning it has no built-in magnet and cannot accept CMSG, DMSG, or EMSG position sensors. Additionally, the 20 mm rear adjuster is a travel stop that sets the end position (180-200 mm window), and the air cushion only controls deceleration; neither component locks or holds the load mechanically.
