Airtac TMIC Guided Cylinder with Guide Unit TMICM25X150
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICM25X150 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 150mm stroke stays true, giving you a ready-to-mount linear slide without a separate guide.

About the Airtac TMIC Guided Cylinder with Guide Unit TMICM25X150
Built around a 25 mm bore, this double-acting guide-frame cylinder merges an MIC round-body unit with a twin-rod aluminium slide running on brass bearings. Needle-set variable air cushions at both ends soak up high-speed shock, while the brass bearing design delivers high torsional stiffness to shrug off radial loads and tool twist. It pushes with 245.3 N and pulls with 206.1 N at 0.5 MPa, peaking at a theoretical 50 kgf.
For sizing, a safe working thrust is roughly 147 N (60 percent of the 0.5 MPa push figure), translating to a vertical lift of about 12.5 kg with a 2:1 margin. Remember that the allowable load is dictated by the load-offset curve, not the thrust. This non-magnet SKU uses a 1/8" port and cannot take a sensor; add the -S variant for CMSG/DMSG/EMSG switches.

| 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 TMICM25X150 Is Used
Pallet Diverting
Handles the side torque of pushing heavy pallets off a high-speed belt, using the 245.3 N thrust and brass bearings to stay square.
Carton Flap Folding
Folds heavy cardboard flaps at speed where the variable air cushion absorbs the end-of-stroke shock without slamming.
Multi-Spindle Drilling
Resists the radial load and twist of a drill block entering material, benefiting from the high torsional stiffness of the brass guide.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICM25X150 the Right Cylinder?
When sizing this 25 mm bore, step down to a TMICM20X150 if your application only needs 157 N of push force at 0.5 MPa, or step up if you exceed the 50 kgf theoretical maximum. Choose this brass-bearing M variant over the linear-bearing TMICL when your load twists the tool or pushes sideways, as the brass provides superior torsional stiffness. The variable air cushion is essential for high-speed moves up to 500 mm/s, decelerating the 150 mm stroke smoothly.
Always verify the allowable load against the TMI/TMIC load-offset curves, since thrust does not equal load capacity. Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG sensors. If position feedback is required, select the -S version. Note that the cushion only decelerates near the stroke end and will not hold the load on air loss; use an external rod lock for that.
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 TMICM25X150 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. The allowable guided load depends on the load-offset distance and must be read from the TMI/TMIC load curves, as thrust is not the load limit.
This specific SKU lacks a magnet and cannot accept CMSG, DMSG, or EMSG switches; you need the -S variant for sensors. The needle-set variable air cushions at both ends only decelerate the piston near the end of the stroke to absorb high-speed shock—they do not function as a lock or brake to hold the load.
