Airtac TMIC Guided Cylinder with Guide Unit TMICM25X100S
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICM25X100S is a genuine guide-frame (guided) pneumatic cylinder — a Ø25mm 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 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 TMICM25X100S
Built around a 25 mm bore, this double-acting guide-frame cylinder integrates an MIC unit into a twin-rod aluminium slide running on brass bearings. Needle-set variable air cushions at both ends soak up high-speed shock, ensuring smooth and square motion, while the brass construction delivers high torsional stiffness to resist radial loads and tool twist. It pushes 245.3 N and pulls 206.1 N at 0.5 MPa, operating through a 1/8" port.
Because the frame carries side load, the actual payload limit depends on the load-offset distance rather than raw thrust. You must confirm allowable load from the maximum-load curves. For a safe working thrust, expect about 147 N (60% of the 0.5 MPa push), which lifts roughly 12.5 kg vertically with a 2:1 margin, load curve permitting. The -S suffix equips the piston with a magnet for position sensing.

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 (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | 289 N |
| Max (@1.0 MPa) | 50 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 TMICM25X100S Is Used
High-Speed Diverting
Lateral sorting arms on packaging lines use the 245.3 N thrust to push cartons at speed, relying on the air cushion to absorb end-of-stroke impact.
Z-Axis Tool Lift
Raising a 12 kg machining head vertically; the brass bearings resist torque while the twin-rod frame keeps the tool square during rapid descent.
Pallet Stopper Gate
Heavy-duty stopping gates on roller conveyors deploy the 100 mm stroke to halt pallets, with the cushion softening the repeated mechanical shock.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICM25X100S the Right Cylinder?
When sizing this 25 mm bore unit, compare it against adjacent bores: the 20 mm frame pushes 157.0 N at 0.5 MPa, while this 25 mm hits 245.3 N. If your application runs at high speeds with heavy payloads, the variable air cushion is essential to prevent end-of-stroke shock. Choose the brass bearing TMICM over the linear-bearing TMICL when your load twists or pushes sideways. Always verify the allowable load from the load-offset curve, as thrust does not dictate the frame limit.
The -S magnet supports CMSG, DMSG, or EMSG switches for end-of-stroke detection. Remember that the cushion only decelerates the piston near stroke end; it does not lock or hold position on air loss. For vertical loads that must resist drifting, add an external rod lock or pilot check valve. The 1/8" port matches the 10 mm rod for robust airflow.

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 TMICM25X100S FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N; at 0.7 MPa it pushes 343.4 N and pulls 288.5 N. The theoretical max is 50 kgf at 1.0 MPa. However, thrust is not the guided-load limit; the actual payload depends on the load-offset distance and must be verified from the TMI/TMIC maximum-load curves.
No, the variable air cushion only decelerates the piston near stroke end to reduce shock; it is not a brake and will not hold position on air loss. For vertical holding, use an external rod lock or pilot check valve. The -S suffix provides a built-in magnet for CMSG, DMSG, or EMSG switches.
