Airtac TMIC Guided Cylinder with Guide Unit TMICM20X75
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICM20X75 is a genuine guide-frame (guided) pneumatic cylinder — a Ø20mm 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 TMICM20X75
Built around a twin-rod aluminium guide frame on brass bearings, this double-acting pneumatic slide delivers 157 N of push force at 0.5 MPa. The integrated variable air cushion at both ends absorbs high-speed end-of-stroke shock, ensuring smooth and quiet motion without twisting the tooling. Brass bearings provide the high torsional stiffness needed when loads push sideways.
At a 75 mm stroke, it offers a safe working thrust of roughly 94 N (about 60% of the 0.5 MPa rating), translating to a vertical push of approximately 8 kg with a 2:1 margin, load permitting. The 1/8 inch port feeds the Ø8 mm rod. Remember that the frame's actual carrying capacity falls as the load sits further from the plate, so always size from the load-offset curve rather than relying on thrust alone. This non-magnet SKU cannot host a sensor.

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 (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | 185 N |
| Max (@1.0 MPa) | 32 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 TMICM20X75 Is Used
High-Speed Transfer Pusher
Uses the 157 N push force to divert lightweight packages on a conveyor, relying on the variable air cushion to quietly stop the 75 mm stroke at high cycle rates.
Side-Loaded Tooling Slide
Moves a small machining head against a workpiece where brass bearings handle the torsional twist and the guide frame keeps the Ø8 mm rod perfectly true.
Vertical Flap Folder
Pushes carton flaps downward with an 8 kg safe vertical margin, using the twin-rod frame to resist off-center bending moments during the folding motion.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICM20X75 the Right Cylinder?
When sizing this unit against the family, step down to the 16 mm bore for lighter 100.5 N push tasks, or step up to the 25 mm bore if you need 245.3 N of push force at 0.5 MPa. Choose this brass-bearing M variant over the linear-bearing L type when your application involves high torsional loads or radial side forces rather than ultra-low friction precision. The needle-set variable air cushion is essential for high-speed cycles carrying heavy tooling, whereas the bumper-only TMIM suits slower, lower-cost setups.
Always verify the allowable payload against the TMI/TMIC maximum-load curves based on your specific load-offset distance. Because this specific SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG position switches; select the -S variant if you require sensing. For applications that must hold position on air loss, add an external rod lock or pilot check valve, as the cushion only decelerates near stroke end.
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 TMICM20X75 FAQ
This 20 mm bore cylinder provides 157 N push and 131.9 N pull at 0.5 MPa, and 219.8 N push at 0.7 MPa, with a theoretical max of 32 kgf at 1.0 MPa. However, thrust is not the load limit; the actual payload it can carry depends on the load-offset distance and must be verified using the TMI/TMIC maximum-load curves.
This specific SKU does not have a magnet, so it cannot accept CMSG, DMSG, or EMSG switches; you need the -S variant for sensing. It uses brass bearings that provide high torsional stiffness and radial-load resistance, paired with a variable air cushion at both ends that decelerates the piston near stroke end to absorb high-speed shock.
