About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X450-50S
The AirTAC MBLCJ32X450-50S is a double-acting, single-rod mini cylinder featuring a 32mm bore and 450mm stroke. It delivers 402N push and 346N pull force at 0.5MPa, with a rear adjustable stroke stopper allowing you to trim the travel by 50mm, creating a usable 400-450mm end-position window. A built-in magnet (-S) enables position detection with CMSG reed or DMSG/EMSG electronic sensors.
Unlike the fixed rubber bumper on an MBLJ, this model uses screw-tunable air cushions at both ends to decelerate heavy loads before impact. The riveted aluminum barrel and 20um hard-chrome plated carbon-steel rod withstand high cycle speeds up to 800mm/s. Because the 450mm stroke is near the 500mm limit for this bore, the 12mm rod is highly susceptible to side-load bending and requires an external guide rail.

| 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 MBLCJ32X450-50S Is Used
Pallet Transfer Stop
Decelerates a 400N loaded pallet at the end of a 450mm transfer line, using the tuned air cushion to prevent impact damage while the 400-450mm stroke window sets the exact stop height.
Router Z-Axis Actuation
Drives a lightweight woodworking router head up and down, relying on the 12mm hard-chrome rod and external linear rail to resist side loads during 450mm plunge routing operations.
Dispenser Head Positioning
Trims the stroke by 50mm to position an adhesive dispensing nozzle precisely over varying product heights, using the DMSG electronic sensor to trigger the shot at the exact 400mm mark.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X450-50S the Right Cylinder?
For lower force needs, the 25mm bore provides 245N push at 0.5MPa; for heavier loads, step up to the 40mm bore offering 628N. Choose the MBLCJ over an MBLJ when your moving mass demands tunable end-deceleration rather than a fixed bumper, or over an MBLC when you need to fine-tune the end position. Remember the rear adjuster is a travel stop, not a lock, and the cushion only decelerates, so use external flow controls or a locking device for position holding. Mounting is limited to Basic, FA flange, or LB foot (no SDB or back-cover options). Replacement requires matching bore 32, stroke 450, adjust 50, G1/8 port, PT thread, and the -S 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 MBLCJ32X450-50S FAQ
At 0.5MPa it provides 402N push and 346N pull force, increasing to 563N push at 0.7MPa. The maximum theoretical force is 82kgf at 1.0MPa. Operating pressure ranges from 0.15 to 1.0MPa.
The rear adjustable stroke is a mechanical stopper that trims the end of travel by up to 50mm (yielding a 400-450mm window), but it does not lock the load in place. The adjustable air cushion is a screw valve that regulates exhaust flow to decelerate the piston near the stroke ends, protecting the end covers from impact.
