About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X450-50
The AirTAC MBLCJ50X450-50 is a double-acting, single-rod mini cylinder featuring a riveted aluminum barrel and a Ø16mm carbon-steel rod with 20µm hard-chrome plating. It delivers 981N of push force at 0.5MPa and 1374N at 0.7MPa. A rear stopper provides an adjustable stroke window from 400mm to 450mm, allowing precise end-position tuning for machinery that requires exact 450mm travel with a 50mm safety margin.
Unlike the fixed rubber bumper found on the MBLJ variant, this model integrates a screw-tunable adjustable air cushion at both ends to decelerate heavy 200kgf loads smoothly. The cushion only governs end-of-stroke speed, while the rear stopper sets the travel limit; neither component mechanically locks or holds the load in place without continuous air pressure. Note that this specific SKU lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensors.

| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 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 MBLCJ50X450-50 Is Used
Injection Mold Ejection
Provides 981N of push at 0.5MPa to eject heavy plastic parts from 450mm deep molds, using the 50mm rear stroke trim to set the exact ejection reach.
Conveyor Pallet Diverter
Uses the tunable air cushion to smoothly decelerate a 450mm lateral diversion of heavy wood pallets, protecting the end covers from impact damage.
Automated Press Feeding
Pushes metal blanks into a stamping press with 1374N at 0.7MPa, relying on the 400-450mm usable window to fine-tune the feed distance.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X450-50 the Right Cylinder?
If you need less force, the 40mm bore variant offers 628N push at 0.5MPa, whereas stepping up to the 63mm bore yields 1558N. The MBLCJ50X450-50 uses a G1/4 port and PT thread. It is limited to Basic, FA flange, or LB foot mounts; there is no SDB pivot or back-cover option. The overall length equals A + 2x450 + 50mm. Because the stroke is 450mm, the small 16mm rod is highly susceptible to side-load bending; an external guide rail is mandatory to prevent cylinder damage. Replacement requires matching the 50mm bore, 450mm stroke, 50mm adjust code, 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 MBLCJ50X450-50 FAQ
At 0.5MPa it provides 981N push and 881N pull. At 0.7MPa push is 1374N. The theoretical maximum is 200kgf at 1.0MPa.
No. This SKU lacks the -S built-in magnet, so it cannot host CMSG, DMSG, or EMSG switches. You must select an -S variant for electronic or reed sensor detection.
