Airtac TMIC Guided Cylinder with Guide Unit TMICM20X25S
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICM20X25S 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 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 TMICM20X25S
Built around a twin-rod aluminium guide frame running on brass bearings, this double-acting guide-frame cylinder integrates an MIC round-body mini cylinder with a variable air cushion at both ends. The brass bearing (M variant) provides high torsional stiffness and resists radial load, making it the right pick when the load twists the tool or pushes sideways. It is a ready-to-mount linear slide, not a bare cylinder.
Operating at a 20 mm bore with a 25 mm stroke, it delivers 157 N of push and 131.9 N of pull at 0.5 MPa through its 1/8" port. For a safe working thrust, figure about 94 N (60% of the 0.5 MPa push), which translates to pushing roughly 8 kg vertically with a 2:1 margin. The maximum load it can carry depends on the load-offset distance, so always size from the TMI/TMIC maximum-load curves rather than relying on 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 TMICM20X25S Is Used
Short-Stroke Stamping
Drives a 25 mm stamping action where the 157 N push force is sufficient, relying on the air cushion to quietly arrest the high-speed impact.
Side-Mounted Diverter
Pushes packages sideways off a belt; the brass bearings handle the torsional twist of an offset tool while the frame keeps the rod true.
Compact Part Ejection
Ejects small parts from a fixture in a tight space, using the 8 mm rod and guided frame to maintain square motion over thousands of cycles.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICM20X25S the Right Cylinder?
When sizing, look both ways: stepping down to the 16 mm bore drops the 0.5 MPa push to 100.5 N, while moving up to the 25 mm bore raises it to 245.3 N. Choose this brass-bearing TMICM build over the linear-bearing TMICL when your application demands high torsional stiffness over low friction. The variable air cushion matters most at high speeds (30-500 mm/s) or with heavier loads, as the needle valves soak up end-of-stroke shock. Because the -S suffix denotes a built-in piston magnet, this SKU is ready for CMSG, DMSG, or EMSG switches. Remember that the frame resists side load but does not hold position on air loss; add an external rod lock or pilot check valve if you need the load held.
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

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 TMICM20X25S 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; the theoretical max is 32 kgf at 1.0 MPa. However, thrust is not the load limit. The maximum allowable load depends on the load-offset distance and must be verified from the TMI/TMIC maximum-load curves.
The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG switches. The variable air cushion only decelerates the piston near the stroke end; it is not a lock or brake. On air loss the piston will drift, so you must use an external rod lock or pilot-operated check valve to hold a vertical load.
