Airtac TMIC Guided Cylinder with Guide Unit TMICM25X75
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICM25X75 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 75mm stroke stays true, giving you a ready-to-mount linear slide without a separate guide.

About the Airtac TMIC Guided Cylinder with Guide Unit TMICM25X75
Built around a 25 mm bore, this twin-rod guide frame pairs an MIC double-acting cylinder with brass bearings to resist heavy radial loads and tool twist. Needle-set variable air cushions at both ends absorb high-speed end-of-stroke shock, ensuring smooth, quiet motion without deflection.
At 0.5 MPa it delivers 245.3 N of push force and 206.1 N of pull force, peaking at a theoretical 50 kgf. For practical sizing, a 0.6 safety factor yields roughly 147 N of working thrust, lifting about 12.5 kg vertically (load curve permitting). Note this non-magnetized SKU uses a 1/8" port and cannot hold position on air loss.

| Acting type | Double acting |
|---|---|
| Fluid | Air (filtered by 40µm element) |
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |

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 TMICM25X75 Is Used
Pallet Diverting
Shifts heavy pallets laterally at high speed, using the brass bearings to absorb the twisting impact while the air cushion decelerates the 245.3 N push smoothly.
Carton Flap Folding
Drives folding arms rapidly on packaging lines where the needle cushion prevents end-stroke jarring that could misalign the tool or tear cardboard.
Vertical Lift Gate
Raises and lowers a loaded transfer gate, safely managing a 12.5 kg vertical payload with a 2:1 margin as long as the offset stays within datasheet limits.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICM25X75 the Right Cylinder?
If 245.3 N of push at 0.5 MPa is excessive, step down to the TMICM20X75, which provides 157.0 N. For heavier drives requiring more than 343.4 N at 0.7 MPa, this 25 mm bore is the largest cushioned option in the series. Choose these brass bearings over the linear TMICL variant when torsional stiffness and sideways load resistance outweigh the need for low-friction precision.
The variable air cushion is essential for 75 mm moves at the 30-500 mm/s guided speed range, preventing harsh impacts. Always size the payload from the TMI load-offset curve rather than the thrust rating, as allowable capacity drops with distance from the plate. Since this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches.
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 TMICM25X75 FAQ
It pushes 245.3 N and pulls 206.1 N at 0.5 MPa, increasing to 343.4 N push at 0.7 MPa, with a 50 kgf theoretical max at 1.0 MPa. However, thrust is not the guided-load limit; the actual payload it can carry depends strictly on the distance from the mounting plate and must be verified using the TMI load-offset curve.
The brass bearings provide high torsional stiffness to handle radial loads, while the variable air cushion at both ends uses a needle valve to decelerate the piston near stroke end for quiet, square stops. This specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG switches; you would need the -S variant for position sensing.
