Airtac TMIC Guided Cylinder with Guide Unit TMICM25X100
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICM25X100 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 TMICM25X100
Built around a twin-rod aluminium guide frame running on brass bearings, the TMICM25X100 is a double-acting guided cylinder that delivers 245.3 N of push force at 0.5 MPa. A needle-set variable air cushion at both ends absorbs high-speed shocks, ensuring the 100 mm stroke completes smoothly and squarely. The 1/8" port feeds the bore rapidly, while the sturdy brass bearings provide high torsional stiffness to resist radial loads and tool twist.
For practical sizing, expect a safe working thrust of roughly 147 N, which translates to pushing about 12.5 kg vertically with a 2:1 safety margin, load permitting. Remember that thrust does not dictate the slide capacity; the maximum payload depends entirely on the load-offset distance and must be verified from the official load curve. This SKU lacks a magnet, so it cannot accept position sensors.

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 TMICM25X100 Is Used
High-Speed Package Diverting
Handles lateral diverting forces on packaging lines using the 245.3 N thrust, while the brass bearings shrug off side loads and the air cushion softens the 100 mm stroke impact.
Vertical Stacking Head
Lifts approximately 12.5 kg of stacked components vertically with a 2:1 safety margin, relying on the twin-rod frame to keep the tooling perfectly square during rapid descent.
Heavy Tool Indexing
Shifts heavy machining fixtures back and forth where torsional stiffness is critical, using the needle-set cushion to absorb the kinetic energy of the moving mass at stroke ends.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICM25X100 the Right Cylinder?
When sizing this unit, compare the thrust against adjacent bores: the TMICM20X100 offers 157.0 N push at 0.5 MPa for lighter duties, while this 25 mm bore provides 245.3 N. If your application exceeds the load curve limits, you may need an entirely different profile. Choose these brass bearings (M) over the linear bearing variant (TMICL) when the load applies heavy torsional stress or pushes sideways. The variable air cushion is essential for high-speed moves near 500 mm/s or heavy payloads, as it prevents end-of-stroke banging.
Always cross-check the load-offset curve to ensure the guide frame can carry your specific moment load. Because this specific SKU ships without a magnet, it cannot support CMSG, DMSG, or EMSG sensors; if you need position detection, order the -S variant. Note that the cushion only decelerates the piston and does not lock the load on air loss—add an external rod lock or pilot check valve for holding requirements.
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 TMICM25X100 FAQ
At 0.5 MPa this 25 mm bore cylinder pushes with 245.3 N and pulls with 206.1 N. At 0.7 MPa, push increases to 343.4 N, with a theoretical maximum of 50 kgf at 1.0 MPa. However, thrust is not the load limit; the actual payload capacity is dictated by the load-offset distance and must be read from the TMI/TMIC maximum-load curves.
This specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG switches; you must order the -S variant for position sensing. It features a variable air cushion at both ends with a 1/8" port, which uses a needle valve to decelerate the piston at high speeds. The cushion only slows the stroke and does not function as a brake or lock.
