About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X450-75S
The AirTAC MBLCJ32X450-75S is a compact double-acting aluminum mini cylinder featuring a rear travel stopper and tunable end-of-stroke deceleration. It delivers 402 N push and 346 N pull force at 0.5 MPa. The rear adjuster allows you to trim up to 75 mm of travel, creating a usable stroke window of 375 to 450 mm for precise end-position tuning.
This SKU includes a built-in magnet (-S) for compatibility with AirTAC CMSG reed and DMSG/EMSG electronic sensors. Unlike the fixed rubber bumper on an MBLJ, the adjustable air cushion at both ends allows screw-tuned deceleration to protect the end covers during fast 450 mm moves. The riveted rolling-packed barrel and 20 µm hard-chrome plated carbon-steel rod provide durable service. Note that the rear stopper sets the travel end but does not hold the load; external guiding is highly recommended for this 450 mm stroke to prevent rod bending.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X450-75S Is Used
Printed Circuit Board Conveyor
Transfers PCB assemblies along a 450 mm stroke, using the 375-450 mm rear adjustment to dial in the exact handoff position without moving the cylinder mounts.
Textile Loom Tensioner
Regulates fabric tension on a weaving machine, relying on the tunable air cushion to smoothly decelerate the 402 N push force at stroke ends without jarring the yarn.
Packaging Carton Flap Folder
Folds corrugated carton flaps on a packaging line, using the -S magnet and a DMSG electronic sensor to confirm full rod extension before the glue applicator fires.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X450-75S the Right Cylinder?
Step down to a 25 mm bore if your application requires only 245 N of push force at 0.5 MPa, or step up to a 40 mm bore for 628 N to handle heavier payloads. Choose this MBLCJ over an MBLJ when your moving mass requires tunable pneumatic cushioning rather than a fixed bumper, or over an MBLC if you need to fine-tune the end position within the 375-450 mm window. The rear adjuster and the air cushion regulate travel and speed, but neither acts as a mechanical lock—rod drift occurs without live air pressure.
Mounting is limited to Basic, FA (flange), or LB (foot); SDB pivot and back-cover options are not available on this series. The replacement match is bore 32, stroke 450, adjust 75, port G1/8, rod thread M10x1.25, PT thread form, and a built-in magnet. Because the 450 mm stroke approaches the 500 mm maximum limit for this bore, always use an external guide to support the Ø12 mm rod and mitigate side-load risks.
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 MBLCJ32X450-75S FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N push and 346 N pull force. At 0.7 MPa, the push force increases to 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa. It operates at speeds between 30 and 800 mm/s.
The 75 mm adjustable stroke is a rear mechanical stopper that lets you shorten the usable travel down to 375 mm from the 450 mm nominal stroke. The adjustable air cushion is a separate screw-tunable valve at each end that regulates pneumatic deceleration to soften impact. Neither feature locks the rod in place; they only set the travel end and slow the speed.
