Airtac TMIC Guided Cylinder with Guide Unit TMICL20X75
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICL20X75 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 TMICL20X75
Built around a twin-rod aluminium guide frame on linear bearings, the TMICL20X75 is a double-acting guided pneumatic cylinder that keeps the rod true under side load and torque. An MIC mini cylinder core provides a needle-set variable air cushion at both ends, soaking up high-speed shock for smooth, square motion at 30-500 mm/s. The unit uses an 8 mm rod and a 1/8" port.
At 0.5 MPa this 20 mm bore delivers 157 N of push force and 131.9 N of pull, climbing to 219.8 N push at 0.7 MPa. For a reliable setup, figure on a safe working thrust around 94 N, which pushes roughly 8 kg vertically with a 2:1 margin. The actual load it can carry depends on the load-offset distance, so always size from the TMI/TMIC maximum-load curves rather than the thrust alone. Note this SKU lacks the -S magnet, so it cannot host CMSG, DMSG or EMSG sensors.

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 TMICL20X75 Is Used
Vertical Push-Up Assembly
Leverages the low-friction linear bearings to raise an 8 kg fixture smoothly, using the 157 N push force at 0.5 MPa for precise vertical placement.
High-Speed Diverting
Uses the needle-set air cushion to absorb end-of-stroke shock during rapid 75 mm lateral sorting moves, keeping the package transfer quiet and square.
Precision Pressing Station
Applies a controlled 94 N safe working thrust to seat delicate electronic components, relying on the twin-rod frame to prevent rod deflection.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICL20X75 the Right Cylinder?
When sizing this unit, look both ways: the smaller TMICL16X50 offers 100.5 N push at 0.5 MPa for lighter jobs, while the larger TMICL25X75 provides 245.3 N if you need more muscle. Choose these linear bearings over the brass-bearing TMICM when low friction and high travel precision matter more than torsional stiffness. The variable air cushion is essential for high-speed or heavy moving loads, as it decelerates the piston cleanly at stroke end.
Remember that the allowable load drops as the mass sits further from the plate, so verify the exact figure from the load-offset curve. Because this specific SKU has no -S suffix, it cannot accept magnetic switches; if you need position feedback, select the -S variant. The guide frame resists side load but will not hold position on air loss, so add an external rod lock or pilot check valve for suspended loads.
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 TMICL20X75 FAQ
This 20 mm bore cylinder delivers 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, with a theoretical max of 32 kgf at 1.0 MPa. Thrust is not the guided-load limit; the actual capacity depends on the load-offset distance and must be verified from the TMI/TMIC maximum-load curves.
This specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG or EMSG switches. It features a needle-set variable air cushion at both ends that decelerates the piston near stroke end for smooth motion, but this is not a lock or brake; the piston will drift on air loss.
