About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X150SCM
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles demanding 150 mm stroke tasks. The Ø25 mm bore uses a 1/8" port and an M10x1.25 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. The riveted construction keeps the body compact while fixed TPU bumper pads absorb the impact at stroke extremes.
Because the 245.3 N rating is theoretical, plan for a safe working load of roughly 147 N at 0.5 MPa. This translates to lifting about 12.5 kg vertically with a 2:1 safety margin, letting you match the actuator to actual part weights. The built-in magnet enables CMSG, DMSG or EMSG switches for position sensing, and the CM round end cover offers a clean rear profile for your assembly.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X150SCM Is Used
Package Diverting Gate
Actuates a routing flap on a packaging line, using the 245.3 N thrust to push heavy cartons smoothly onto a secondary belt.
Vertical Parts Lift
Raises lightweight industrial totes 150 mm, safely lifting components up to 12.5 kg within a 2:1 safety margin during transfer.
Lab Sample Ejection
Ejects processed specimen trays from a testing station, where the stainless build resists humidity and chemical wipe-downs.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X150SCM the Right Cylinder?
When sizing this 150 mm stroke unit, verify your actual load against the 12.5 kg vertical lift capacity. If you need less force, the Ø20 bore provides 157.0 N push at 0.5 MPa; for heavier drives, the Ø32 bore offers 402.2 N. Remember that venting the air or centering the valve causes the piston to drift, as the TPU pads only decelerate the end of travel rather than locking the rod. To hold a suspended load securely, add an external rod lock or a pilot-operated check valve. The 150 mm stroke demands careful alignment to prevent rod bending under side loads.
This SKU includes the -S magnet for position feedback and the CM rear cover. You can mount it using LB foot brackets, FA flanges, SDB pivot blocks or TC trunnions. The Ø25 mm dimensions conform to the ISO 6432 mounting interface, ensuring it drops directly into standard mini-cylinder brackets and clevises.
Quick checklist
