Airtac TMIC Guided Cylinder with Guide Unit TMICL25X250S
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICL25X250S is a genuine guide-frame (guided) pneumatic cylinder — a Ø25mm 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 250mm stroke stays true, giving you a ready-to-mount linear slide without a separate guide.

About the Airtac TMIC Guided Cylinder with Guide Unit TMICL25X250S
Built around a 25 mm bore and a 250 mm stroke, this twin-rod guide-frame unit integrates an MIC round-body cylinder with linear bearings for precise, low-friction motion. Needle-set variable air cushions at both ends absorb high-speed shock, ensuring smooth and square travel without side-load drift. A 1/8" port supplies the air, and the -S suffix equips the piston with a magnet for position sensing.
The double-acting thrust class is substantial: 245.3 N push and 206.1 N pull at 0.5 MPa, rising to 343.4 N push at 0.7 MPa, with a theoretical maximum of 50 kgf at 1.0 MPa. For reliable operation, a safe working thrust is roughly 147 N, or about 12.5 kg of vertical push with a 2:1 margin. The frame resists torque, but the actual payload you can mount depends on the load-offset curve, not the raw thrust.

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 TMICL25X250S Is Used
Vertical Press Assembly
Leverages the 245.3 N push force and low-friction linear bearings to press small bearings into housings smoothly from above.
High-Speed Diverting
Uses the 250 mm stroke and needle-set air cushions to swiftly divert heavy packages without end-of-stroke slamming.
Precision Guided Clamping
Relies on the twin-rod frame to clamp off-center parts securely, resisting torque while maintaining alignment.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICL25X250S the Right Cylinder?
When sizing, compare this 25 mm bore against the 20 mm option, which delivers 157 N push at 0.5 MPa, to ensure you have enough force without oversizing. If 245.3 N is insufficient, a larger custom frame would be required. Choose these linear bearings over the brass-bearing TMICM variant when friction and vertical push-up accuracy matter more than torsional stiffness. The variable air cushion is essential for high-speed moves, but remember the frame only resists side load—it does not hold position on air loss, so add an external rod lock if needed.
Always verify your allowable payload against the TMI/TMIC maximum-load curves based on your specific offset distance. Because this SKU includes the -S magnet, you can directly mount CMSG, DMSG, or EMSG sensors for end-of-stroke confirmation.

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 TMICL25X250S FAQ
At 0.5 MPa it provides 245.3 N push and 206.1 N pull. At 0.7 MPa it provides 343.4 N push and 288.5 N pull. The theoretical maximum is 50 kgf at 1.0 MPa. However, thrust is not the guided-load limit; the actual payload capacity depends on the load-offset distance and must be read from the TMI/TMIC maximum-load curves.
The linear bearings offer high precision and low friction, making the unit ideal for vertical push-up moves. The variable air cushion at both ends decelerates the piston near stroke ends to absorb shock. The cushion only decelerates and does not lock; on air loss the piston will drift, so an external rod lock is required for position holding. The -S magnet allows use of CMSG, DMSG, or EMSG sensors.
