About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X450-50
The AirTAC MBLCJ32X450-50 is a compact double-acting mini cylinder featuring a riveted aluminum barrel and a rear stroke adjuster. It provides a push force of 402 N at 0.5 MPa. The rear stopper allows you to trim up to 50 mm of travel, creating a usable end-position window of 400 to 450 mm to fine-tune machine timing.
This model uses an adjustable air cushion at both ends to tune end-of-stroke deceleration, protecting the end covers from impact during fast moves. Because this SKU lacks the -S magnet code, it cannot accept a CMSG reed or DMSG electronic position sensor. The 12 mm carbon-steel rod features 20 µm hard-chrome plating to resist wear, while the grease-retaining piston seal ensures consistent lubrication over long cycles.

| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 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 MBLCJ32X450-50 Is Used
Textile Loom Beater
Drives the 450 mm reed motion at 402 N push force, using the 50 mm rear stroke trim to perfectly time the weft insertion without mechanical stops.
Pallet Pusher Arm
Transfers heavy pallets along a roller conveyor, relying on the adjustable air cushions to softly decelerate the 450 mm travel and prevent load spillage.
Long-Stroke Riveter
Applies 346 N pull force to seat long rivets in aircraft panel assembly, where the 400-450 mm usable window allows minute on-machine stroke calibration.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X450-50 the Right Cylinder?
Stepping down to the 25 mm bore yields 245 N push at 0.5 MPa, while stepping up to the 40 mm bore provides 628 N. Choose the MBLCJ variant if you need fixed 450 mm travel without the rear adjuster, or the MBLJ if you only need a fixed rubber bumper instead of tunable air cushions. The rear adjuster sets a travel stop and the cushion only decelerates; neither holds the 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 32 mm bore, 450 mm stroke, 50 mm adjust code, G1/8 PT port, and no magnet. At 450 mm stroke, the 12 mm rod is highly susceptible to side-load bending, so an external guide rail is mandatory to prevent premature seal failure.
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 MBLCJ32X450-50 FAQ
At 0.5 MPa, the push force is 402 N and the pull force is 346 N. At 0.7 MPa, the push force reaches 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa.
The rear adjuster mechanically trims the travel end position within a 400-450 mm window, acting as a physical stop. The adjustable air cushion only regulates pneumatic deceleration speed near the stroke ends to prevent hard impacts; neither system locks the load in place.
