Airtac TMIC Guided Cylinder with Guide Unit TMICM20X125
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICM20X125 is a genuine guide-frame (guided) pneumatic cylinder — a Ø20mm double-acting MI mini cylinder built into a twin-rod guide unit running on brass bearings. The guide frame absorbs side load and torque so the 125mm stroke stays true, giving you a ready-to-mount linear slide without a separate guide.

About the Airtac TMIC Guided Cylinder with Guide Unit TMICM20X125
Built around a twin-rod aluminium guide frame on brass bearings, this double-acting guide-frame cylinder integrates an MIC mini body with a variable air cushion at both ends. The brass bearing spec gives high torsional stiffness to shrug off radial loads, while the needle-set cushions absorb high-speed end-of-stroke shock for smooth, square motion.
Delivering 157 N of push force and 131.9 N of pull force at 0.5 MPa via a 1/8" port, it provides a safe working thrust of roughly 94 N. This translates to pushing about 8 kg vertically with a 2:1 safety margin, load curve permitting. Remember the frame's allowable load drops as the offset distance grows, so always confirm the exact capacity from the TMI/TMIC load curves rather than relying on thrust alone. This non-magnet SKU cannot take a sensor.

| Guide | Twin-rod guide frame, double-rod unit |
| Port size | 1/8" |
| Acting type | Double acting |
|---|---|
| Fluid | Air (filtered by 40µm element) |
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 500 mm/s |

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 TMICM20X125 Is Used
High-Speed Diverting
With 157 N of thrust and end cushions to absorb kinetic energy, this cylinder cleanly diverts lightweight cartons on a conveyor at high cycle rates without slamming.
Vertical Form Press
Pushing roughly 8 kg of vertical mass with a 2:1 margin, the brass bearings resist off-center loads during packaging flap folding or light pressing tasks.
Gripper Transfer
The twin-rod frame holds a parts gripper true against torsional twist during rapid horizontal transfers, while the air cushion decelerates the 125 mm stroke smoothly.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICM20X125 the Right Cylinder?
When sizing, look at both force and guidance. If 157 N push at 0.5 MPa is excessive, step down to the TMICM16X125 (100.5 N push). If your payload needs more muscle, the TMICM25X125 offers 245.3 N. Choose these brass bearings (M) over the linear bearing variant (TMICL) when the load twists the tool or pushes heavily sideways. The variable air cushion is essential for high-speed cycles, but note this specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG switches. If you need position sensing, order the -S version. Always verify the allowable load against the load-offset curve.
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 TMICM20X125 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. However, thrust is not the load limit. The allowable load depends on the load-offset distance and must be read from the TMI/TMIC maximum-load curves.
This specific SKU has no magnet, so it cannot accept CMSG, DMSG, or EMSG switches; you need the -S variant for sensing. It features a variable air cushion at both ends that uses needle valves to decelerate the piston near stroke end for quiet motion. The cushion is not a lock or brake, and the frame will not hold position on air loss.
