Airtac TMIC Guided Cylinder with Guide Unit TMICM25X25
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICM25X25 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 25mm stroke stays true, giving you a ready-to-mount linear slide without a separate guide.

About the Airtac TMIC Guided Cylinder with Guide Unit TMICM25X25
Built around a twin-rod aluminium guide frame running on brass bearings, the AirTAC TMICM25X25 is a double-acting guided pneumatic cylinder engineered for exact linear motion. A needle-set variable air cushion at both ends absorbs high-speed end-of-stroke shock, ensuring smooth and quiet operation. As a ready-to-mount linear slide, it carries side load and torque so the rod stays true.
This 25 mm bore model delivers 245.3 N of push force at 0.5 MPa, yielding a safe working thrust of roughly 147 N. It pushes about 12.5 kg vertically with a 2:1 safety margin, load curve permitting. Remember that the allowable load is dictated by the load-offset distance, not the thrust. This non-magnetized SKU uses a 1/8" port and cannot accept a sensor.

| Acting type | Double acting |
|---|---|
| Fluid | Air (filtered by 40µm element) |
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |

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 TMICM25X25 Is Used
High-Speed Product Diversion
Uses the 245.3 N thrust to push heavy cartons sideways on a conveyor, relying on the brass bearings to resist torsional twist during rapid lateral strokes.
Pallet Flap Folding
Folds cardboard flaps at speed where the needle-set air cushion absorbs the end-of-stroke impact, keeping the packaging station quiet and square.
Short-Stroke Stamping
Drives a 25 mm stamping operation where the twin-rod guide frame maintains tool alignment under offset loads, preventing rod deflection.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICM25X25 the Right Cylinder?
When sizing this unit, consider both the force and the bearing type. If 245.3 N of push at 0.5 MPa is excessive, step down to the TMICM20X25 which provides 157.0 N. If you need more power, there is no larger standard TMICM bore, so you would look outside the family. Choose these brass bearings (M) when the load twists the tool or pushes sideways, whereas the TMICL variant with linear bearings suits low-friction precision needs.
The variable air cushion is vital for high-speed or heavy moving loads, decelerating the piston smoothly before the end of stroke. Always verify the maximum payload against the TMI/TMIC load-offset curve, as thrust does not set the load limit. Because this specific SKU lacks the -S magnet, it cannot support CMSG, DMSG, or EMSG switches; order a -S variant if position sensing is required.
Quick checklist
- ✓ Required thrust at your working pressure
- ✓ Load and offset within the load curve
- ✓ Bearing: brass (torque) vs linear (precision)
- ✓ Stroke and mounting space
- ✓ Magnet (-S) for sensors?
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 TMICM25X25 FAQ
At 0.5 MPa it provides 245.3 N push and 206.1 N pull; at 0.7 MPa it provides 343.4 N push and 288.5 N pull, with a theoretical max of 50 kgf at 1.0 MPa. The allowable load is not determined by thrust but by the load-offset distance, which must be checked against the TMI/TMIC maximum-load curves.
This specific SKU does not have a magnet and therefore cannot accept CMSG, DMSG, or EMSG sensors; you need the -S variant for switches. The brass bearings provide high torsional stiffness and radial-load resistance, making this the right choice when the load pushes sideways or twists the tool.
