Airtac TMIC Guided Cylinder with Guide Unit TMICM20X75S
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICM20X75S 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 TMICM20X75S
Built around a 20 mm bore double-acting MIC unit, this guide-frame cylinder integrates twin rods and brass bearings to resist side load and torque. A needle-set variable air cushion at both ends absorbs high-speed shock, ensuring smooth and square motion without end-of-stroke slamming. It pushes with 157 N and pulls with 131.9 N at 0.5 MPa, making it a robust mid-range linear slide.
The brass bearing design provides high torsional stiffness, ideal when the payload twists or pushes sideways. For sizing, a safe working thrust is roughly 94 N (about 60% of the 0.5 MPa push force), translating to a vertical lift of around 8 kg with a 2:1 safety margin. Remember the 1/8 inch port and that the actual allowable payload depends on the load-offset distance—always verify capacity from the load curve rather than relying on thrust alone.

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 TMICM20X75S Is Used
Pallet Diverting
Pushes lightweight pallets sideways off a high-speed belt, using the variable air cushion to decelerate the 8 kg payload smoothly without slamming.
Flap Folding
Folds heavy cardboard flaps on a packaging line where the side load would twist a bare cylinder, relying on brass bearings for torsional stiffness.
Parts Ejection
Ejects molded parts at 500 mm/s, using the 1/8 inch port for rapid actuation while the twin-rod frame keeps the tooling perfectly square.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICM20X75S the Right Cylinder?
When sizing, compare this 20 mm bore pushing 157 N @0.5 MPa against the 16 mm bore (100.5 N) for lighter tasks, or step up to the 25 mm bore (245.3 N) if you need more force. Choose these brass bearings (TMICM) over the linear-bearing TMICL variant when your application involves high torsional loads or lateral stress rather than ultra-low friction precision. The variable air cushion is essential for high-speed operations (up to 500 mm/s) to prevent harsh impacts.
Because the frame resists side load but does not hold position on air loss, add an external rod lock or pilot check valve if you need to prevent drift. This -S model includes a piston magnet for CMSG, DMSG, or EMSG sensors; without the -S suffix, the cylinder cannot accept switches. Always cross-check your mounting offset against the load curve to ensure the guide frame is not overloaded.

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 TMICM20X75S FAQ
At 0.5 MPa it pushes 157 N and pulls 131.9 N; at 0.7 MPa it pushes 219.8 N and pulls 184.7 N. The theoretical maximum is 32 kgf at 1.0 MPa. However, thrust is not the guided-load limit—you must confirm the allowable payload from the load-offset curve, as capacity drops the further the load sits from the plate.
The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG sensors. The variable air cushion only decelerates near the stroke end; it is not a brake. The guide frame resists side load but on air loss the piston drifts, so use an external rod lock or pilot check valve for position holding.
