Airtac TMIC Guided Cylinder with Guide Unit TMICL20X100
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICL20X100 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 100mm stroke stays true, giving you a ready-to-mount linear slide without a separate guide.

About the Airtac TMIC Guided Cylinder with Guide Unit TMICL20X100
Built around an MIC mini cylinder inside a twin-rod aluminium guide frame, the TMICL20X100 delivers square, true motion on linear bearings. The needle-set variable air cushion at both ends soaks up high-speed shock for quiet deceleration, while the frame carries side load and torque.
This 20 mm bore unit pushes 157 N and pulls 131.9 N at 0.5 MPa, offering a safe working thrust of roughly 94 N. It pushes about 8 kg vertically with a 2:1 margin, load curve permitting. It uses a 1/8" port and an Ø8 mm rod. Remember the load it can carry falls as the load sits further from the plate, so size from the load-offset curve, not from thrust alone.

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 TMICL20X100 Is Used
Vertical Push-Up Pressing
Ideal for downward pressing and push-up tasks needing low friction, using the 8 kg vertical capacity safely to seat components without side-load drift.
High-Speed Diverting
The needle-set air cushions absorb end-of-stroke shock during fast 100 mm diverting strokes, keeping the guided payload stable and square on the line.
Precision Component Placement
Linear bearings maintain high travel accuracy for locating small parts, letting the twin-rod frame resist any torsional stress from off-center tooling.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICL20X100 the Right Cylinder?
When sizing both ways, step down to the 16 mm bore for lighter loads (100.5 N push @0.5 MPa) or up to the 25 mm bore for heavier jobs (245.3 N push @0.5 MPa). 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 moves or heavy loads, but it only decelerates near stroke end—it is not a lock.
Always verify the allowable load against the TMI/TMIC maximum-load curves based on your load-offset distance. This specific SKU lacks a magnet (-S), so it cannot take CMSG, DMSG, or EMSG sensors; order the -S variant if you need position detection. For holding a load on air loss, add 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 TMICL20X100 FAQ
At 0.5 MPa it pushes 157 N and pulls 131.9 N; at 0.7 MPa it pushes 219.8 N and pulls 184.7 N, with a theoretical max of 32 kgf at 1.0 MPa. Thrust is not the guided-load limit: the allowable load drops as the offset from the plate grows, so always size from the TMI/TMIC load-offset curve.
This non-S SKU has no magnet and cannot take CMSG, DMSG, or EMSG switches; order the -S version for sensors. The variable air cushion on linear bearings only decelerates the piston near stroke end for smooth motion—it does not lock or hold position. On air loss the piston drifts, so use an external rod lock or pilot check valve to hold a load.
