About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X150-75
The AirTAC MBLCJ25X150-75 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. The rear stopper allows you to trim up to 75 mm of travel, creating a usable 75-150 mm stroke window. Driven by a Ø10 mm carbon-steel rod with 20 µm hard-chrome plating, it delivers 245 N push and 206 N pull at 0.5 MPa. This 150 mm stroke suits mid-range positioning tasks on compact machinery.
Unlike the base MBLJ with its fixed rubber bumper, the screw-tunable air cushion on this unit decelerates heavier or faster moving loads right at the stroke ends to protect the end covers. The riveted rolling-packed barrel and heterogeneous two-way grease-retaining piston seal maintain consistent lubrication. Note that this specific SKU lacks the -S magnet option, meaning it cannot accept CMSG, DMSG, or EMSG position sensors. The adjuster is a travel stop, not a load lock; external guides are recommended for this length to prevent rod bending.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X150-75 Is Used
PCB Conveyor Diverter
Pushes lightweight routing gates on SMT lines using 245 N force, while the 75-150 mm stroke window dials in exact board transfer alignment without repositioning brackets.
Pick-and-Place Z-Axis
Lowers vacuum grippers in assembly cells where the adjustable air cushion brakes the 150 mm descent, preventing hard impacts that misalign delicate surface-mounted components.
Filament Tensioning Arm
Maintains tension on fiber-winding machines; the rear stopper sets a precise 75 mm travel limit to prevent slack, while the cushion softens the rapid reversal strokes.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X150-75 the Right Cylinder?
If you need less force, step down to the Ø20 bore, which yields 157 N push at 0.5 MPa. For heavier pushing, the Ø32 bore provides 402 N. Choose this MBLCJ over the MBLJ when your cycle speeds require tunable end-of-stroke deceleration rather than a simple fixed bumper, or over the MBLC if you need to fine-tune the travel end. Remember that neither the rear adjuster nor the cushion acts as a lock; the rod drifts without live air, so use an external locking mechanism for fail-safe holding. Mounting is limited to Basic, FA, or LB styles (no SDB or back-cover options). For a direct replacement, match the 25 mm bore, 150 mm stroke, 75 mm adjust, G1/8 port, PT thread, and confirm no magnet is fitted. At 150 mm stroke, the small 10 mm rod is susceptible to side-load bending, so external guidance is essential.
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 MBLCJ25X150-75 FAQ
At 0.5 MPa, this 25 mm bore cylinder provides 245 N push and 206 N pull force. At 0.7 MPa, the push force is 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa.
The rear adjustable stroke is a mechanical travel stop that lets you trim the usable window down to 75-150 mm. The adjustable air cushion is a screw-tunable valve that decelerates the piston near the end covers. Neither holds position; without live air, the rod drifts, so you need an external lock for fail-safe holding.
