Airtac TMIC Guided Cylinder with Guide Unit TMICL20X75S
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICL20X75S is a genuine guide-frame (guided) pneumatic cylinder — a Ø20mm double-acting MI mini cylinder built into a twin-rod guide unit running on linear 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 TMICL20X75S
Built around a 20 mm bore double-acting MIC unit, this guide-frame cylinder integrates twin rods and linear bearings to absorb side load and torque. A variable air cushion at both ends soaks up high-speed shock, ensuring smooth and square motion at 30-500 mm/s. The 1/8" port feeds the chamber, delivering 157 N of push force at 0.5 MPa.
Linear bearings provide the low friction and high precision needed for accurate vertical push-up moves, making it superior to brass-bearing alternatives when smooth travel matters. For sizing, expect a safe working thrust of about 94 N, pushing roughly 8 kg vertically with a 2:1 margin. The frame resists side load but does not hold position on air loss, so use an external rod lock for suspended loads. The allowable payload depends on the load-offset distance, so verify limits from the load curve.

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 TMICL20X75S Is Used
Vertical Press Fit
Pushes about 8 kg safely with a 2:1 margin, using linear bearings to maintain a true vertical path for inserting delicate electronics.
High-Speed Divert
Cycles rapidly to deflect packages on a belt, relying on the variable air cushion to absorb the shock at the 75 mm stroke end.
Pick And Place Z-Axis
Lifts and lowers components smoothly, where the low-friction linear bearings prevent side-load drift during rapid transfer.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICL20X75S the Right Cylinder?
When sizing this unit, step down to the 16 mm bore for lighter duties (100.5 N push at 0.5 MPa) or up to the 25 mm bore for heavier tasks (245.3 N push at 0.5 MPa). Choose this linear-bearing version over the brass-bearing TMICM when low friction and precise travel outweigh torsional stiffness needs. The needle-set air cushion is essential for high-speed or heavy loads, preventing end-of-stroke impact.
Always size the payload using the load-offset curve, as thrust alone does not dictate the guide frame capacity. Because this SKU includes the -S magnet, you can directly mount CMSG, DMSG, or EMSG sensors for position detection. If a power loss occurs, the piston drifts since the cushion only decelerates near the stroke end and acts as no brake.

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 TMICL20X75S FAQ
At 0.5 MPa it pushes 157 N and pulls 131.9 N; at 0.7 MPa it pushes 219.8 N, with a theoretical max of 32 kgf at 1.0 MPa. Thrust is not the guided-load limit, so you must verify the actual payload against the load-offset curve.
Yes, the -S suffix means a magnet is built in for CMSG, DMSG, or EMSG switches. The variable air cushion only decelerates near the stroke end; it does not lock, so the piston drifts on air loss and needs an external rod lock to hold.
