Airtac TMIC Guided Cylinder with Guide Unit TMICL25X25S
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICL25X25S 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 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 TMICL25X25S
Built around an MIC mini cylinder inside a twin-rod aluminium guide frame, the TMICL25X25S brings needle-set variable air cushions to high-speed linear-bearing motion. The twin rods absorb side load and torque, keeping the Ø10 mm rod true for short 25 mm moves, while the cushions soak up end-of-stroke shock for quiet, square stops. A 1/8" port feeds the bores.
This 25 mm bore generates 245.3 N of push thrust at 0.5 MPa (343.4 N at 0.7 MPa, 50 kgf theoretical max at 1.0 MPa). For a reliable setup, figure a safe working thrust around 147 N, which translates to pushing about 12.5 kg vertically with a 2:1 margin. The actual payload you can mount depends entirely on the load-offset distance, so size the slide from the maximum-load curve rather than the thrust figures. The -S suffix adds a piston 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 TMICL25X25S Is Used
Short-Stroke Press Fit
Drives a 12 kg bearing block into a housing with a 25 mm stroke, using the air cushion to soften the final impact for precise, damage-free seating.
High-Speed Diverter
Pushes light cartons off a fast belt where the twin-rod frame resists the side torque of off-center contact and linear bearings ensure smooth retraction.
Precision Component Insertion
Seats delicate electronic connectors into housings, relying on low-friction linear travel to maintain alignment and the magnet for immediate confirmation.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICL25X25S the Right Cylinder?
When sizing this 25 mm bore unit against the family, step down to the 20 mm model if your job needs only 157 N of push at 0.5 MPa, or look beyond the range if 343.4 N at 0.7 MPa is insufficient. Choose these linear bearings over the brass-bearing TMICM when low friction and high travel precision outweigh the need for maximum torsional stiffness. The variable air cushion is essential for heavier or fast-moving payloads that would slam hard against a fixed bumper.
Always verify the allowable load against the load-offset curve, as thrust does not dictate the guide frame capacity. The included -S magnet supports CMSG, DMSG, and EMSG sensors for stroke confirmation. Remember the cushion only decelerates the piston near the end of travel; it does not lock the load, so add an external rod lock or pilot check valve if you need to prevent drift on air loss.

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 TMICL25X25S FAQ
This 25 mm bore cylinder pushes 245.3 N and pulls 206.1 N at 0.5 MPa, increasing to 343.4 N push at 0.7 MPa, with a theoretical max of 50 kgf at 1.0 MPa. The guide frame's allowable payload is strictly set by the load-offset distance, so you must verify your setup against the TMI/TMIC maximum-load curves rather than relying on the thrust figures.
Linear bearings provide low-friction, high-precision travel ideal for vertical push-up moves, while the needle-set variable air cushion at both ends decelerates the piston to absorb high-speed shock. The -S magnet enables CMSG, DMSG, or EMSG switches for sensing. The cushion only softens the stop; it does not lock the load, so the piston will drift on air loss unless you fit an external rod lock or pilot check valve.
