About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X100-10
The AirTAC MBLCJ25X100-10 is a compact double-acting aluminum mini cylinder featuring a rear travel stopper and tunable air cushions at both ends. The 10 mm rear adjuster creates a usable extension window of 90 to 100 mm, letting you dial in the exact endpoint for a 245 N push at 0.5 MPa. Unlike the fixed rubber bumper found on the base MBLJ, the screw-tunable cushions on this unit decelerate heavier loads at the stroke extremes, protecting the end covers from impact damage.
This 25 mm bore uses a G1/8 port and a Ø10 mm hard-chrome plated carbon steel rod with an M10x1.25 end thread. Because this specific SKU lacks the -S magnet suffix, it cannot accept an AirTAC CMSG, DMSG, or EMSG position sensor. The riveted rolling-packed aluminum barrel retains grease via a heterogeneous two-way piston seal, ensuring consistent friction at speeds between 30 and 800 mm/s. Remember the rear stopper sets the travel end but does not lock the load; you must maintain live air to hold position.

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 MBLCJ25X100-10 Is Used
PCB Depaneling Saw Feed
Uses the 90-100 mm fine stroke window to advance a circular saw blade into assembled printed circuit boards, relying on the adjustable air cushion to stop the 245 N feed without jarring the fragile fiberglass.
Micro-Dispenser Valve Stroke Set
Trims the exact 10 mm rear travel to meter a two-part epoxy valve, using the dual end cushions to prevent fluid splashing when the rod reverses direction at high speed.
Lightweight Coil End-Straightening
Pushes a 25 mm bore carbide die against copper wire coil ends, applying 206 N of pull force on retract while the tunable cushion absorbs the kinetic energy of the rapid 100 mm stroke.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X100-10 the Right Cylinder?
Choose this 25 mm bore when you need 245 N of push force at 0.5 MPa (206 N pull) with precise end-position tuning. If your payload is lighter, step down to the 20 mm bore, which provides 157 N push; for heavier drives, step up to the 32 mm bore, delivering 402 N push. This model replaces an MBLCJ25X100-10 by matching the 25 mm bore, 100 mm stroke, 10 mm adjust code, G1/8 port, PT thread, and Basic mounting without a magnet.
Select the MBLCJ over the MBLJ when your cycle speeds demand adjustable end-of-stroke deceleration rather than a fixed bumper. Mounting is limited to Basic, FA flange, or LB foot brackets—there is no SDB pivot or back-cover option. Since the overall length equals A + 2 x stroke + adjust, the 10 mm rear adjuster adds to the footprint. The 100 mm stroke is well within the 300 mm standard cap for this bore, but always support side loads with an external guide to protect the 10 mm rod from 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 MBLCJ25X100-10 FAQ
At 0.5 MPa this 25 mm bore cylinder outputs 245 N push and 206 N pull. At 0.7 MPa the push increases to 343 N. The maximum theoretical force is 50 kgf at the 1.0 MPa pressure limit, with an operating range of 0.15 to 1.0 MPa.
This specific SKU lacks the -S suffix, meaning it has no built-in magnet and cannot accept CMSG, DMSG, or EMSG position switches. The 10 mm rear mechanism is a travel stop that sets the 90-100 mm usable window, and the adjustable air cushion only decelerates the piston; neither component mechanically locks or holds the load without continuous air pressure.
