Airtac TMIC Guided Cylinder with Guide Unit TMICL20X25
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICL20X25 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 25mm stroke stays true, giving you a ready-to-mount linear slide without a separate guide.

About the Airtac TMIC Guided Cylinder with Guide Unit TMICL20X25
Built around a 20 mm bore double-acting MIC cylinder, this guide-frame unit delivers 157 N of push force at 0.5 MPa through a compact 25 mm stroke. The twin-rod aluminium frame runs on linear bearings, providing low-friction, high-precision travel that excels in vertical push-up applications. A needle-set variable air cushion at both ends absorbs high-speed shock, ensuring smooth, quiet deceleration without square impact.
While the cylinder generates 131.9 N of pull force at 0.5 MPa, the actual payload you can mount depends entirely on the load-offset distance. Always size the unit from the TMI/TMIC maximum-load curves rather than relying on thrust alone. This specific SKU lacks a magnet (-S) and therefore cannot accept CMSG, DMSG, or EMSG position switches. It features an 8 mm rod and a 1/8" 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 TMICL20X25 Is Used
Short-Stroke Vertical Push-Up
Leveraging the 157 N push force and low-friction linear bearings, this 25 mm stroke unit precisely lifts and seats light components without side-load drift.
High-Speed Part Insertion
The needle-set air cushion absorbs the impact of rapid 25 mm insertions, protecting the 8 mm rod and ensuring smooth, square stops at cycle end.
Guided Diverter Stopper
Twin-rod guidance handles the torsional load of halting moving product, while the cushioned frame provides quiet, shock-free deceleration on the line.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICL20X25 the Right Cylinder?
For lighter duties, the 16 mm bore variant offers 100.5 N of push force, while stepping up to the 25 mm bore provides 245.3 N if your application demands more thrust. Choose this linear-bearing (L) construction over the brass-bearing TMICM when friction and positioning accuracy matter more than torsional stiffness. The variable air cushion is essential if you are cycling at higher speeds or moving heavier masses, as it prevents end-of-stroke shock.
Remember that the guide frame resists side load but does not hold position on air loss; the piston will drift. For load holding, integrate an external rod lock or pilot check valve. Since this non-magnet SKU cannot host a sensor, order the -S version if you require CMSG/DMSG/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 TMICL20X25 FAQ
At 0.5 MPa it provides 157 N push and 131.9 N pull; at 0.7 MPa it provides 219.8 N push and 184.7 N pull, with a theoretical max of 32 kgf at 1.0 MPa. However, thrust is not the guided-load limit; the allowable payload falls as the load sits further from the plate and must be verified from the TMI/TMIC load-offset curves.
This specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG switches; you need the -S variant for sensors. It features a variable air cushion at both ends that uses needle adjustment to decelerate the piston near stroke end for smooth motion, but it is not a lock or brake and will not hold position on air loss.
