Airtac TMIC Guided Cylinder with Guide Unit TMICL20X150
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICL20X150 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 TMICL20X150
Built around a 20mm bore double-acting MIC unit, the TMICL20X150 guide-frame cylinder integrates a twin-rod aluminium slide running on linear bearings. It delivers 157N of push and 131.9N of pull thrust at 0.5MPa, making it a solid mid-range choice for 150mm travel. A needle-set variable air cushion at both ends absorbs high-speed end-of-stroke shock, ensuring quiet, square motion without metal-on-metal banging.
The linear bearings provide low-friction, high-precision guidance that excels in vertical push-up applications, moving smoothly at 30-500mm/s. Based on the 0.5MPa push rating, you get a safe working thrust of roughly 94N, or about 8kg of vertical lift with a 2:1 safety margin—provided the load sits within the allowable limits of the load-offset curve. Note that this specific SKU lacks a magnet (-S) and cannot accept CMSG/DMSG/EMSG sensors. The fluid port is 1/8".

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 TMICL20X150 Is Used
Vertical Push-Up Lifting
Leverages the low-friction linear bearings to raise 8kg jigs smoothly over 150mm without side-load drift, using the 2:1 safety margin from its 157N push force.
High-Speed Transfer Divert
Shifts light packages across a belt at speed; the needle-set air cushion absorbs the end-of-stroke shock to keep the twin-rod frame square and quiet.
Precision Glue Dispensing
Moves a dispensing head accurately along the 150mm path, where the high-precision linear bearing ensures the 20mm bore maintains a true, wobble-free path.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICL20X150 the Right Cylinder?
When sizing this 20mm bore unit, check both neighbours: step down to a 16mm frame for lighter 100.5N push loads, or move up to a 25mm bore if you need the 245.3N push force to drive heavier tooling. Choose this TMICL linear-bearing version over the brass-bearing TMICM when smooth, low-friction travel and vertical push-up precision matter more than torsional stiffness. The variable air cushion is essential if you are cycling at high speeds or moving significant mass, as it prevents harsh impacts at the 150mm stroke ends.
Always derive your payload limit from the TMI/TMIC maximum load curves rather than the thrust numbers, because the allowable weight drops as the load sits further from the guide plate. Since this model has no -S suffix, it ships without a magnet and cannot support position sensing; add the -S option if your control system requires CMSG, DMSG, or EMSG switches. For loads that must stay put on air loss, add an external rod lock or pilot check valve, as the cushion only decelerates and never locks.
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 TMICL20X150 FAQ
At 0.5MPa it provides 157N push and 131.9N pull; at 0.7MPa it yields 219.8N push and 184.7N pull, with a theoretical max of 32kgf at 1.0MPa. However, thrust is not the guided-load limit—you must confirm the actual allowable payload from the TMI/TMIC load-offset curve based on how far the weight sits from the guide plate.
This specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG switches. It features a variable air cushion at both ends that uses needle adjustment to decelerate the piston near stroke end for smooth stops; it is not a braking device and will not hold the load on air loss.
