About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X250-100S
The AirTAC MBLCJ25X250-100S is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and tunable air cushions at both ends. It delivers 245 N of push force at 0.5 MPa. The 100 mm rear adjuster allows you to fine-tune the travel endpoint anywhere within a 150-250 mm usable window, ensuring exact arrival positioning for dynamic tasks.
Unlike the fixed rubber bumper found on the base MBLJ, the screw-tunable adjustable air cushion on this SKU decelerates heavier loads smoothly near the stroke ends, protecting the end covers from impact damage. The built-in magnet (-S) supports CMSG reed and DMSG or EMSG electronic sensors for position detection. Note that the rear adjuster acts strictly as a travel stop, not a lock; the cylinder cannot hold a load in place without continuous air pressure.

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 MBLCJ25X250-100S Is Used
PCB Edge Conveyor Routing
Provides 245 N of push force to actuate routing gates on automated PCB conveyors, using the 150-250 mm stroke window to perfectly time board transfers without hard impacts.
Textile Loom Tensioner
Adjusts yarn tensioning arms in textile machinery; the tunable air cushion decelerates the rapid 250 mm extension smoothly, preventing sudden snags or thread breakage.
Packaging Flap Folder
Drives carton flap folders at high cycling speeds, relying on the end-of-stroke cushioning to protect the aluminum end covers while the built-in magnet confirms fold completion.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X250-100S the Right Cylinder?
Stepping down from this 25 mm bore (245 N push @0.5 MPa), the 20 mm bore offers 157 N for lighter loads, while stepping up to the 32 mm bore provides 402 N for heavier tooling. Choose this MBLCJ over the MBLJ when your application's speed requires active deceleration rather than a fixed rubber bumper, or over the MBLC when you need to trim the travel endpoint within the 150-250 mm window.
For replacement, match the 25 mm bore, 250 mm stroke, 100 mm adjust code, G1/8 port, and M10x1.25 rod thread. The default PT thread form and built-in magnet must be specified. Mounting is limited to Basic, FA, or LB styles; no SDB pivot or back-cover options exist. Because the stroke is 250 mm, the 10 mm piston rod is susceptible to bending under lateral stress—always use an external guide rail to support the payload.
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 MBLCJ25X250-100S 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 rear adjuster is a mechanical travel stop that sets your usable stroke window between 150 mm and 250 mm. The adjustable air cushion is a separate screw-tunable feature that regulates end-of-stroke deceleration. Neither feature locks or holds the load in place; external mechanics are required for position holding.
