Airtac TMIC Guided Cylinder with Guide Unit TMICM25X80S
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICM25X80S is a genuine guide-frame (guided) pneumatic cylinder — a Ø25mm double-acting MI mini cylinder built into a twin-rod guide unit running on brass bearings. The guide frame absorbs side load and torque so the 80mm stroke stays true, giving you a ready-to-mount linear slide without a separate guide.

About the Airtac TMIC Guided Cylinder with Guide Unit TMICM25X80S
Built around a 25 mm bore double-acting MIC unit, this guide-frame cylinder integrates twin rods and brass bearings to deliver 245.3 N of push force at 0.5 MPa. The brass bearing design provides high torsional stiffness, making it the right choice when your payload twists the tooling or pushes sideways. A needle-set variable air cushion at both ends absorbs high-speed end-of-stroke shock for smooth, quiet motion.
While the thrust is substantial, the actual payload you can mount depends on the distance from the guide plate, so always confirm the allowable weight from the load-offset curve. For a 2:1 safety margin, this bore pushes roughly 12.5 kg vertically on air. Because this is the -S variant, it includes a piston magnet for position sensing. It uses a 1/8" port and a 10 mm rod. Remember that the cushion only decelerates the stroke; it does not lock position on air loss.

Specifications follow the official AirTAC TMI/TMIC datasheet. Guide frame & fixed plate: aluminum alloy; matching cylinder: MI/MIC round-body mini cylinder. Allowable load depends on the load-offset distance — consult the TMI/TMIC maximum-load curves before final selection. Thread options: PT (blank) / G.
Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | 289 N |
| Max (@1.0 MPa) | 50 kgf | |
Thrust equals the underlying MI cylinder. The usable load a guide frame can carry is limited by the load-offset curve, not by thrust alone — always check both. Actual force is lower than theoretical due to friction and back-pressure.

Where the Airtac TMIC Guided Cylinder with Guide Unit TMICM25X80S Is Used
High-Speed Product Diversion
Uses the 245.3 N thrust to push heavy cartons sideways on a belt while the brass bearings resist the twisting impact of uneven loads.
Vertical Stamping Mount
Drives a small marking head down at speed; the dual air cushions absorb the end-of-stroke shock to protect the tooling and maintain square alignment.
Pallet Stop Gate
Acts as a guided stop for incoming pallets. The twin-rod frame handles the side impact while the cushion brings the motion to a quiet halt.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICM25X80S the Right Cylinder?
If you need less force, the TMICM20X80S steps down to 157 N of push at 0.5 MPa, while this 25 mm bore is the top standard size in the cushioned family, pushing 245.3 N. Choose this brass-bearing M variant over the linear-bearing TMICL when your application involves high torsional loads rather than low-friction precision. The variable air cushion is essential when cycling at high speeds with heavy tooling, preventing harsh impacts.
Always size the unit using the maximum load-offset curves, not the thrust numbers, since allowable load drops as the payload sits further from the plate. This -S model supports CMSG, DMSG, and EMSG sensors. If your payload must stay put during an air loss, add an external rod lock or pilot check valve, as the cushion only decelerates near the stroke end.

Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Keep the load within the load-offset curve.
- check Mount on a flat, rigid surface using the fixed plate.
- check Do not exceed the rated speed (30-500 mm/s).
- check Installation by qualified personnel per AirTAC docs.
Airtac TMIC Guided Cylinder with Guide Unit TMICM25X80S FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N. At 0.7 MPa it pushes 343.4 N and pulls 288.5 N. The theoretical max is 50 kgf at 1.0 MPa. However, thrust is not the load limit; the actual payload you can carry depends on the distance from the guide plate and must be verified using the TMI/TMIC maximum load-offset curves. It features a 1/8" port.
The -S suffix means it has a built-in magnet for CMSG, DMSG, and EMSG switches. The variable air cushion at both ends only decelerates the piston near the stroke end to absorb shock; it does not lock or hold position. If air is lost, the piston will drift. For load holding, you need an external rod lock or pilot check valve.
