Airtac TMIC Guided Cylinder with Guide Unit TMICM20X200S
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICM20X200S 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 200mm stroke stays true, giving you a ready-to-mount linear slide without a separate guide.

About the Airtac TMIC Guided Cylinder with Guide Unit TMICM20X200S
Twin-rod brass bearings and a needle-set air cushion at each end define this 20 mm bore guided slide, keeping motion square and quiet even at high speed. As a double-acting unit it delivers 157 N of push force at 0.5 MPa, making it a solid choice for mid-weight tooling. The built-in magnet (-S) supports CMSG, DMSG, and EMSG position sensing.
Because the frame carries the torque, thrust is not the load limit; you must size the allowable payload from the TMI load-offset curve. For context, this bore yields a safe working thrust of about 94 N, or roughly 8 kg of vertical push with a 2:1 margin, load curve permitting. It connects via a 1/8 inch port.

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 TMICM20X200S Is Used
High-Speed Diverting
Uses the 157 N push force to deflect heavy cartons on a packaging line, relying on the air cushion to absorb end-of-stroke shock.
Z-Axis Tool Lift
Raises an 8 kg pneumatic clamp vertically, with brass bearings preventing torsional twist during the 200 mm travel.
Pallet Stopper Gate
Acts as a guided stop gate for mid-weight pallets, where the twin-rod frame resists side impacts without binding.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICM20X200S the Right Cylinder?
If 157 N of push at 0.5 MPa is too much, step down to the TMICM16, which provides 100.5 N; if you need more power, the TMICM25 offers 245.3 N. Choose this brass-bearing variant when the load twists or pushes sideways, whereas the TMICL linear-bearing version suits low-friction precision. The variable air cushion is essential for damping heavy loads at speed, but remember it only decelerates near stroke end—it is not a lock. For position holding on air loss, add an external rod lock or pilot check valve. Finally, ensure you order the -S magnet option if you need CMSG, DMSG, or EMSG 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 TMICM20X200S FAQ
At 0.5 MPa it pushes 157 N and pulls 131.9 N; at 0.7 MPa it pushes 219.8 N. The theoretical max is 32 kgf at 1.0 MPa. However, thrust is not the load limit—you must verify the allowable payload against the TMI load-offset curve based on your specific mounting distance.
No, the variable air cushion only decelerates the piston near stroke end; it does not lock or hold the load on air loss. You need an external rod lock or pilot check valve for holding. The -S option includes a magnet for CMSG, DMSG, and EMSG switches.
