About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X100-100
The AirTAC MBLCJ25X100-100 is a compact double-acting aluminum mini cylinder featuring a rear adjustable stroke and an adjustable air cushion at both ends. It delivers 245 N push and 206 N pull force at 0.5 MPa. The rear stopper allows you to trim up to 100 mm of travel, creating a usable stroke window of 0 to 100 mm for precise end-position tuning.
This model uses a Ø10 mm carbon-steel rod with 20 µm hard-chrome plating and a grease-retaining piston seal inside a riveted aluminum barrel. Because this specific SKU lacks the -S magnet suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor. The adjustable air cushion lets you screw-tune end-of-stroke deceleration to protect the end covers during faster moves, a step up from the fixed rubber bumper found on the MBLJ series.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X100-100 Is Used
PCB Depaneling Saw
Tuned to a 0-50 mm window, the 245 N push stroke feeds a circular blade into assembled PCB panels while the adjustable air cushion prevents sudden impact at the cut endpoint.
Label Dispenser Tamp
Trims 100 mm of rear travel for a short 10 mm tamping motion, applying labels to packaging with 206 N pull force without bouncing the lightweight applicator head.
Textile Loom Guide
Uses the full 100 mm travel to shift a yarn guide bar across the loom width, relying on the riveted aluminum body and end cushions to sustain 800 mm/s cycling.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X100-100 the Right Cylinder?
If you need less force, step down to the Ø20 bore (157 N push @0.5 MPa); if your load is heavier, step up to the Ø32 bore (402 N push @0.5 MPa). Choose this MBLCJ over the MBLJ when your cycle speeds require tunable pneumatic deceleration rather than a fixed bumper, or over the MBLC if your application requires trimming the end position. Remember, the rear adjuster is a travel stop and the cushion only decelerates; neither holds a load, so use an external lock for position holding. Mounting is limited to Basic, FA, or LB; no SDB or back-cover options exist. For a direct replacement, match the 25 mm bore, 100 mm stroke, 100 mm adjust code, G1/8 PT port, and confirm no magnet is fitted.
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 MBLCJ25X100-100 FAQ
At 0.5 MPa, this Ø25 mm double-acting cylinder provides 245 N push and 206 N pull force. At 0.7 MPa, the push force is 343 N, with a theoretical maximum of 50 kgf at 1.0 MPa. The standard stroke limit for the Ø25 bore is 300 mm, and this 100 mm stroke is well within that range.
This specific SKU lacks the -S suffix, so it has no built-in magnet and cannot accept CMSG, DMSG, or EMSG sensors. The 100 mm adjustment code means the rear stopper lets you trim travel down to a 0 mm usable window; this sets the end position but does not lock the load, while the separate adjustable air cushion only tunes end-of-stroke deceleration.
