Airtac TMIC Guided Cylinder with Guide Unit TMICM25X125
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICM25X125 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 TMICM25X125
Built around a 25 mm bore, this twin-rod guide-frame unit pairs a double-acting MIC cylinder with brass bearings and a variable air cushion at both ends. The brass bearing provides high torsional stiffness to resist radial loads, while the needle-set cushion soaks up high-speed shock for smooth, square stops.
It pushes with 245.3 N and pulls with 206.1 N at 0.5 MPa via a 1/8" port. For a safe 2:1 margin, expect a vertical push of about 12.5 kg, load curve permitting. Note this SKU lacks a magnet, so it cannot take CMSG/DMSG/EMSG switches.
Airtac TMIC Guided Cylinder with Guide Unit TMICM25X125 Technical Specifications

| 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 TMICM25X125 Is Used
Pallet Diverting
Uses the 245.3 N push force to deflect heavy pallets on a high-speed line, relying on the brass bearings to absorb side impact without twisting.
Case Flap Folding
Folds heavy cardboard flaps at speed where the variable air cushion ensures a quiet, square stop at the end of the 125 mm stroke.
Tote Pushing
Ejects loaded totes sideways with high torsional stiffness, handling the offset weight without guide rod deflection.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICM25X125 the Right Cylinder?
At 0.5 MPa this 25 mm bore generates 245.3 N of push force. If your application is lighter, the 20 mm bore TMICM20X125 offers 157.0 N; if you need more power, this is the largest cushioned brass option. Choose the brass M bearing when the load twists or pushes sideways, or switch to the TMICL for linear precision.
The variable air cushion is essential for high-speed moves up to 500 mm/s. Remember that allowable load drops as the offset from the plate grows, so always size from the load-offset curve. For position holding on air loss, add an external rod lock since the cushion only decelerates.
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 TMICM25X125 FAQ
It pushes 245.3 N and pulls 206.1 N at 0.5 MPa, pushing 343.4 N at 0.7 MPa, with a 50 kgf theoretical max at 1.0 MPa. The actual load it carries is limited by the load-offset distance, so you must verify capacity from the load curve rather than relying on thrust.
This specific SKU has no magnet and cannot accept CMSG, DMSG, or EMSG switches; you need the -S variant for sensors. It uses brass bearings for high torsional stiffness under radial loads, and the variable air cushion decelerates the piston near stroke end but does not lock the load.
