About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X175-100
The AirTAC MBLCJ25X175-100 is a compact double-acting aluminum mini cylinder featuring a rear travel stopper and tunable air cushions at both ends. It delivers 245 N of push force and 206 N of pull force at 0.5 MPa. The 100 mm adjustment code allows you to trim the rear stroke, creating a usable travel window of 75 to 175 mm for precise positioning. This makes it highly effective for varying material thicknesses on packaging lines.
Unlike the base MBLJ which relies on a fixed rubber bumper, this MBLCJ variant uses screw-tunable deceleration to protect the end covers during faster, heavier moves. The riveted rolling-packed aluminum barrel and heterogeneous two-way grease-retaining piston seal minimize friction and extend operational life. Note that this specific SKU lacks a built-in magnet, so it cannot accept a CMSG, DMSG, or EMSG position sensor switch. The 10 mm carbon-steel rod features 20 µm hard-chrome plating to resist corrosion and wear.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X175-100 Is Used
Thermoforming Press Ejection
Provides 245 N of push force to strip formed plastic sheets from molds, using the 75-175 mm stroke window to adapt to varying sheet depths.
Filling Valve Actuation
Tunes the air cushion to decelerate the 10 mm rod smoothly at high speeds when opening and closing beverage filling nozzles, preventing liquid splash.
PCB Conveyor Routing
Uses the adjustable travel stopper to deflect populated circuit boards into testing lanes, with the compact riveted body fitting inside tight machine frames.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X175-100 the Right Cylinder?
If you need less force, stepping down to the 20 mm bore yields 157 N of push at 0.5 MPa, whereas stepping up to the 32 mm bore provides 402 N. Choose this MBLCJ over an MBLJ when your cycle speed demands tunable end-of-stroke cushioning rather than a fixed bumper, or over an MBLC when you need on-the-fly stroke length adjustments. The rear stopper sets the travel end but does not hold the load, and the cushion only decelerates; neither acts as a lock, so external guides are needed for position holding. Mounting is limited to Basic, FA flange, or LB foot styles, as no SDB pivot or back-cover options exist. For a direct replacement, match the 25 mm bore, 175 mm stroke, 100 mm adjust code, 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 MBLCJ25X175-100 FAQ
At 0.5 MPa, it provides 245 N push and 206 N pull force, increasing to 343 N push at 0.7 MPa, with a maximum theoretical output of 50 kgf at 1.0 MPa. The 100 mm adjustment code allows you to trim the rear stroke, creating a usable travel window of 75 to 175 mm.
No, this specific SKU does not have a built-in magnet, meaning it cannot accept CMSG reed or DMSG/EMSG electronic sensors. You would need an MBLCJ model with the -S suffix for position detection.
