Airtac TMIC Guided Cylinder with Guide Unit TMICL20X150S
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICL20X150S 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 150mm stroke stays true, giving you a ready-to-mount linear slide without a separate guide.

About the Airtac TMIC Guided Cylinder with Guide Unit TMICL20X150S
Built around an MIC mini cylinder inside a twin-rod aluminium guide frame, the TMICL20X150S delivers true linear motion on linear bearings with a variable air cushion at each end. This 20 mm bore, 150 mm stroke double-acting slide handles side load and torque, keeping the 8 mm rod square while absorbing high-speed shocks for quiet operation.
It pushes with 157 N and pulls with 131.9 N at 0.5 MPa via its 1/8" port. For a safe working thrust, plan around 94 N, which lets you push about 8 kg vertically with a 2:1 margin. Remember the load curve dictates the true capacity based on offset, not thrust. The -S suffix means a magnet is fitted for 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 TMICL20X150S Is Used
Vertical Push-Up Assembly
Lifts and presses 8 kg payloads smoothly using the low-friction linear bearings, with the air cushion decelerating the 150 mm stroke softly at the bottom.
High-Speed Diverting
Shifts small packages laterally at speed; the twin-rod frame absorbs side torque while the cushion prevents end-of-stroke banging.
Precision Pick-and-Place
Moves parts accurately over 150 mm with the 157 N thrust class, relying on the magnet for end-position confirmation.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICL20X150S the Right Cylinder?
If you need less force, the 16 mm bore offers 100.5 N push at 0.5 MPa, while the 25 mm bore steps up to 245.3 N for heavier jobs. Choose these linear bearings over the brass-bearing TMICM when low friction and precise travel matter more than torsional stiffness. The needle-set air cushion shines at high speeds or with heavy payloads.
Always size the unit from the load-offset curve, since thrust does not equal guided load capacity. The -S magnet on this 150 mm stroke model enables solid-state sensing, but note the frame only resists side load—it will not hold position on air loss without an external rod lock or pilot check valve.
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 TMICL20X150S 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. Thrust is not the guided load limit—you must confirm the allowable payload from the TMI/TMIC load-offset curve based on your specific geometry.
It uses a variable air cushion at both ends to decelerate high-speed motion smoothly, not as a braking lock. The -S suffix provides a built-in magnet for CMSG, DMSG or EMSG switches. The linear bearings ensure high precision and low friction for vertical push-up moves.
