Airtac TMIC Guided Cylinder with Guide Unit TMICM25X125S
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICM25X125S 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 125mm stroke stays true, giving you a ready-to-mount linear slide without a separate guide.

About the Airtac TMIC Guided Cylinder with Guide Unit TMICM25X125S
Built around a 25 mm bore double-acting MIC unit, this guide-frame cylinder integrates a variable air cushion at both ends to absorb high-speed shocks. The twin-rod aluminium frame rides on brass bearings, delivering high torsional stiffness and true linear motion for heavy side loads. With a 125 mm stroke and a 1/8" port, it pushes 245.3 N and pulls 206.1 N at 0.5 MPa.
Thrust does not dictate the payload limit; the allowable load falls as the distance from the plate increases, so always size from the TMI/TMIC load-offset curve. For a safe working thrust, expect around 147 N, or roughly 12.5 kg of vertical push with a 2:1 margin. The -S suffix means a piston magnet is built in for CMSG, DMSG, or EMSG sensors.

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 TMICM25X125S Is Used
Pallet Diverting
Shifts heavy pallets sideways at speed, using the 245.3 N thrust and brass bearings to resist the twisting impact during high-cycle transfers.
Carton Flap Folding
Folds thick cardboard flaps rapidly where the variable air cushion quietly stops the 125 mm stroke without slamming the tooling.
Vertical Lift Gate
Raises and lowers a loading gate; the twin-rod frame keeps the load square, though an external check valve is needed to hold position on air loss.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICM25X125S the Right Cylinder?
If 245.3 N of push at 0.5 MPa is excessive, step down to the TMICM20X125S which provides 157.0 N; for heavier drives, the 25 mm bore is the largest cushioned option in this family. Choose these brass bearings over the linear TMICL variant when the load twists the tooling or applies high radial force. The needle-set air cushion is essential for fast 30-500 mm/s cycles, decelerating the mass smoothly at stroke ends.
Remember that the frame resists side load but does not lock position on air loss; add an external rod lock or pilot check valve if you need to hold a vertical load. Verify the allowable payload from the load-offset curve, and confirm the -S magnet is specified if you need to mount position switches.

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 TMICM25X125S 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, with a theoretical max of 50 kgf at 1.0 MPa. However, thrust is not the guided payload limit; the allowable load depends on the offset distance and must be read from the TMI/TMIC load curve.
The -S suffix provides a built-in magnet for CMSG, DMSG, or EMSG switches. The variable air cushion at both ends only decelerates the piston near the stroke ends for smooth stops; it is not a brake, so the cylinder will drift on air loss and requires an external rod lock to hold position.
