About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X300-20S
The AirTAC MBLCJ32X300-20S is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. It delivers 402 N push and 346 N pull force at 0.5 MPa. The rear stopper allows you to trim up to 20 mm of travel, creating a precise 280-300 mm usable stroke window for exact end-of-cycle positioning.
Unlike the fixed rubber bumper found on the MBLJ series, the screw-tunable air cushions on this SKU decelerate heavy loads at high speeds to protect the end covers. The -S code denotes a built-in magnet for CMSG reed or DMSG/EMSG electronic sensor switches. Note that the 300 mm stroke pushes the limits of the Ø12 mm rod; an external guide is recommended to prevent side-load bending. The riveted rolling-packed barrel and grease-retaining piston seal ensure long service life.

| 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 MBLCJ32X300-20S Is Used
Textile Loom Weft Insertion
Uses the 280-300 mm adjustable stroke window to precisely time weft insertion on high-speed looms, relying on the tunable air cushion to decelerate the 402 N thrust without slamming the end cover.
PCB Conveyor Stopping
Acts as an adjustable stop gate on a printed circuit board conveyor, where the 20 mm rear trim fine-tunes the board halt position and the -S magnet triggers a DMSG sensor for the next robotic pickup.
Carton Flap Folding
Drives a 300 mm flap-folding arm on packaging lines, using the dual end cushions to control the rapid extension and retraction of the 32 mm bore to prevent carton crushing.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X300-20S the Right Cylinder?
Choose this 32 mm bore when you need 402 N of push force at 0.5 MPa. If your load is lighter, step down to the 25 mm bore (245 N push); if you need more power, step up to the 40 mm bore (628 N push). Compared to the fixed-stroke MBLC, this model grants 20 mm of rear travel adjustment. The rear adjuster sets the physical stop, while the cushions only control deceleration—neither component locks the rod in place, so external holding mechanisms are required for dead-stop positioning.
For replacement matching, verify the 32 mm bore, 300 mm nominal stroke, 20 mm adjust code, G1/8 port, PT thread form, and the -S magnet. Mounting is strictly limited to Basic, FA flange, or LB foot styles; no SDB pivot or back-cover options exist for this series. Because the stroke reaches 300 mm, always support the load to minimize rod deflection.
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 MBLCJ32X300-20S 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 the 1.0 MPa operating pressure limit.
The adjustable stroke uses a rear mechanical stopper to trim the travel window down to 280-300 mm. The adjustable air cushion uses a needle screw to tune end-of-stroke deceleration speed. Neither feature locks or holds the load in place; the cushion only slows the piston, and the stopper only sets the travel endpoint.
