About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X150-100
The AirTAC MBLCJ25X150-100 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. The 100mm adjustment code lets you trim the rear travel, creating a usable stroke window of 50 to 150mm. Driven by a Ø10mm rod through a G1/8 port, it delivers 245N push and 206N pull at 0.5 MPa. This 150mm stroke suits mid-length indexing on compact machinery.
Unlike the base MBLJ with its fixed rubber bumper, this MBLCJ uses screw-tunable end-of-stroke deceleration to absorb kinetic energy, protecting the end covers during faster cycles. The riveted rolling-packed barrel and grease-retaining two-way piston seal maintain smooth operation, while the 20μm hard-chrome carbon-steel rod resists wear. Note that this specific SKU lacks a built-in magnet (-S), so it cannot accept CMSG, DMSG, or EMSG position sensors.

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 MBLCJ25X150-100 Is Used
Textile Loom Beater
Drives the beating mechanism at 245N push, using the 50-150mm window to fine-tup reed travel and the air cushion to soften the end impact on high-speed looms.
PCB Router Trimmer
Positions the routing head across a 150mm span, relying on tunable deceleration to prevent jarring stops that could snap delicate carbide cutting bits.
Carton Flap Folder
Actuates the folding arm with 206N pull force, adjusting the rear stopper to accommodate varying carton widths without repositioning the entire cylinder block.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X150-100 the Right Cylinder?
If you need less force, step down to the 20mm bore (157N push @0.5 MPa); for heavier drives, step up to the 32mm bore (402N push @0.5 MPa). Choose the MBLCJ over the MBLJ when your moving mass requires tunable end-cushioning rather than a fixed bumper, or pick the MBLC if you want fixed stroke lengths without a rear adjuster. Remember, the rear stopper sets the travel end and the cushion only decelerates; neither holds the load in place without live air pressure. Mounting is limited to Basic, FA flange, or LB foot (no SDB or back-cover options), extending overall length to A + 2 x stroke + adjust. For exact drop-in replacement, match bore 25, stroke 150, adjust 100, G1/8 port, PT thread, and no magnet.
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 MBLCJ25X150-100 FAQ
At 0.5 MPa, this 25mm bore cylinder provides 245N push and 206N pull. At 0.7 MPa, the push force is 343N. The maximum theoretical force is 50 kgf at 1.0 MPa operating pressure.
The 100mm rear adjuster acts as a mechanical travel stop, setting your usable stroke window between 50 and 150mm. The adjustable air cushion is a screw-tunable valve that decelerates the piston near the end covers. Neither feature locks or holds the load; you need live air or an external lock for position holding.
