About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X175-10
The AirTAC MBLCJ25X175-10 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 and 206 N of pull force at 0.5 MPa. The rear stopper allows you to trim up to 10 mm of travel, creating a usable stroke window of 165 to 175 mm. This 175 mm travel is well-suited for intermediate reach operations on small automated equipment.
Unlike the base MBLJ which relies on a fixed rubber bumper, this MBLCJ variant uses screw-tunable air cushions to decelerate the rod near each end cap, absorbing kinetic energy to protect the end covers during faster cycling. The riveted rolling-packed barrel and heterogeneous grease-retaining piston seal maintain consistent lubrication over the 30-800 mm/s speed range. Because this specific SKU lacks the -S magnet suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor switch. The adjuster acts purely as a mechanical travel stop and does not lock the load in place.

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 MBLCJ25X175-10 Is Used
PCB Router Z-Axis
Drives the vertical plunge of a light-duty PCB routing spindle, using the 165-175 mm window to set exact cutting depth and the air cushion to soften the rapid retract.
Label Applicator Arm
Pivots a label wipe-down brush over a 175 mm arc, with the tunable cushion preventing brush bounce on the stroke end to ensure bubble-free label adhesion.
Textile Yarn Guide
Traverses a yarn guide across a 175 mm winding drum, relying on the adjustable stroke to match the drum width and the cushion for smooth reversal at 800 mm/s.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X175-10 the Right Cylinder?
If you need less force, stepping down to the 20 mm bore yields 157 N of push at 0.5 MPa, while stepping up to the 32 mm bore provides 402 N. Choose this MBLCJ over an MBLJ when your moving mass requires tunable end-of-stroke deceleration rather than a fixed bumper impact, or over an MBLC when you need to fine-tune the travel end position. Remember that the rear stroke adjuster and the air cushion regulate motion but do not hold the load; a separate external locking mechanism is required for position holding. Mounting is limited to Basic, FA flange, or LB foot styles as this series omits the SDB pivot and back-cover options. For an exact replacement, match the 25 mm bore, 175 mm stroke, 10 mm adjust code, G1/8 port, default PT thread, and no-magnet configuration. At 175 mm stroke, the 10 mm rod is susceptible to bending under lateral loads, so an external guide rail should be used 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 MBLCJ25X175-10 FAQ
At 0.5 MPa, the push force is 245 N and the pull force is 206 N. At 0.7 MPa, the push force is 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa.
The rear adjustable stroke is a mechanical travel stop that limits the rod extension to a 165-175 mm window, whereas the adjustable air cushion uses a needle screw to tune the rate of pneumatic deceleration near the end caps. Neither mechanism locks the load; the cushion only decelerates, and the stopper only sets the end position.
