About the Airtac MIJ Adjustable Cylinder MIJ8X50-10S
Dial in exact forward stops on-site with the AirTAC MIJ8X50-10S, a round-body stainless steel mini cylinder featuring a 10mm extend-stroke adjustment window. An external stop screw lets you shorten the forward end position from the 50mm nominal down to 40mm, absorbing setup tolerances without changing the part number. Retract remains full stroke.
Built with a stainless barrel and rod for mild washdown resistance, this double-acting Ø8 unit conforms to ISO 6432 mounting dimensions. It delivers 25.1N push force at 0.5MPa, translating to a safe working load of about 15N or a 1.3kg vertical lift with a 2:1 margin. The M5x0.8 port and M4x0.7 male rod thread keep the envelope compact, while the included -S piston magnet supports CMSG, DMSG and EMSG sensors.

Where the Airtac MIJ Adjustable Cylinder MIJ8X50-10S Is Used
Micro-actuation
Drives tiny 15N pick-and-place nozzles, using the 10mm stop screw to dial in the exact forward reach for delicate component handling.
Small part diverter
Pushes lightweight items on a packaging line, trimming the extend stroke on-site to accommodate different box widths without swapping hardware.
Lab test positioning
Moves a 1.3kg sample tray into a test station, relying on the stainless build for mild corrosion resistance and the adjustable stop for precise end positioning.
Is the Airtac MIJ Adjustable Cylinder MIJ8X50-10S the Right Cylinder?
For lighter tasks, no smaller MIJ bore exists, but stepping up to a Ø10 increases the 0.5MPa push force to 39.3N if you need more authority. The 10mm external stop screw here is perfect for changeover jobs where you trim the extend end to hit varying stops, though it only trims the forward position and does not lock mid-stroke. Because a plain cylinder drifts on air loss, add an external pilot check valve if the load must hold position. Mount via standard LB, FA or TC brackets (SDB pivot blocks are not offered on this adjustable variant) and use the -S magnet for switch readiness.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check Use correct back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MIJ Adjustable Cylinder MIJ8X50-10S FAQ
At 0.5MPa it provides 25.1N push and 18.8N pull; at 0.7MPa it provides 35.2N push and 26.4N pull. The theoretical maximum force is 5.1kgf at 1.0MPa. The air port is M5x0.8 and the male rod thread is M4x0.7.
An external stop screw shortens the extend stroke by up to 10mm (usable forward range 40-50mm), but retract remains full and the screw is not a mid-stroke lock. The -S suffix means a piston magnet is built-in for CMSG, DMSG or EMSG sensors.
