Airtac TMIC Guided Cylinder with Guide Unit TMICL25X125
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICL25X125 is a genuine guide-frame (guided) pneumatic cylinder — a Ø25mm double-acting MI mini cylinder built into a twin-rod guide unit running on linear 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 TMICL25X125
Built around a 25 mm bore double-acting MIC unit, this guide-frame cylinder integrates twin-rod linear bearings to deliver 245.3 N of push thrust at 0.5 MPa. The 1/8" port feeds the air circuit, while the needle-set variable air cushion at both ends soaks up high-speed shock for smooth, square motion. A 125 mm stroke falls well within the 250 mm standard limit for this bore.
Because the aluminium frame carries side load and torque, the piston rod stays true during travel. For vertical push-up moves, expect a safe working thrust of roughly 147 N, or about 12.5 kg of lifting force with a 2:1 safety margin (load curve permitting). This specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors.

|---|---|
| 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 TMICL25X125 Is Used
Vertical Pressing
Pushes down with 245.3 N at 0.5 MPa, using the linear bearings to keep the tooling square during high-speed press cycles.
Pallet Transfer
Handles side loads during 125 mm pallet stops or lifts, relying on the twin-rod frame to prevent rod deflection.
Carton Forming
Extends rapidly to fold heavy carton blanks, with the needle-set air cushion absorbing end-of-stroke shock quietly.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICL25X125 the Right Cylinder?
At the top of the TMICL range, this 25 mm bore delivers 245.3 N push and 206.1 N pull at 0.5 MPa. If your application requires less force, the 20 mm bore offers 157.0 N of push thrust. Always size from the load-offset curve rather than raw thrust, as the allowable load drops significantly the further the mass sits from the guide plate.
Choose these linear bearings over the brass-bearing TMICM when low friction and high travel precision outweigh torsional stiffness. The variable air cushion is essential for high-speed moves, but remember it only decelerates near stroke end—it is not a lock. For position holding on air loss, add an external rod lock or pilot check valve. Note that without the -S magnet option, this unit cannot host position sensors.
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 TMICL25X125 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 guided-load limit—you must confirm the actual allowable load from the TMI/TMIC maximum load-offset curve based on your specific geometry.
This SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG switches; you need the -S variant for sensors. The linear bearings provide low-friction precision, and the variable air cushion decelerates the piston near stroke end, but neither acts as a brake. For holding a load vertically on air loss, install an external rod lock or pilot check valve.
