Airtac TMIC Guided Cylinder with Guide Unit TMICL25X75S
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICL25X75S 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 75mm stroke stays true, giving you a ready-to-mount linear slide without a separate guide.

About the Airtac TMIC Guided Cylinder with Guide Unit TMICL25X75S
Built around an MIC mini cylinder housed in a twin-rod aluminium guide frame, this double-acting unit runs on linear bearings for low-friction, high-precision motion. The 25 mm bore generates 245.3 N of push force at 0.5 MPa, while a needle-set variable air cushion at both ends soaks up high-speed shock for smooth, square stops. Because the -S suffix denotes a built-in piston magnet, you can mount CMSG, DMSG or EMSG sensors for exact stroke detection.
The linear bearings make this model the top choice for vertical push-up moves and smooth travel where accuracy matters more than the torsional stiffness of the brass-bearing TMICM. It pushes about 12.5 kg vertically with a 2:1 safety margin, load curve permitting. Remember that the frame resists side load but does not hold position on air loss; the cushion only decelerates near stroke end. Always confirm the exact allowable load from the TMI/TMIC load-offset curves, as thrust is not the guided-load limit.

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 TMICL25X75S Is Used
Vertical Press Push-Up
Leverages the linear bearings for precise vertical descent, using the 245.3 N thrust to seat components before the air cushion decelerates the stroke.
High-Speed Diverting
Handles rapid side-loading on a conveyor line, where the twin-rod frame keeps the motion true and the needle cushion absorbs the end-stop impact.
Carton Flap Folding
Delivers accurate horizontal folding force on a packaging line, benefiting from low-friction linear travel and sensor-ready position detection.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICL25X75S the Right Cylinder?
Size this 25 mm bore model by checking the load-offset curve first, since the allowable payload drops as the distance from the guide plate increases. If your application requires less force, step down to the 20 mm TMICL (157.0 N push at 0.5 MPa); if you need more, there is no larger standard TMICL bore, so consider a different frame. Choose this linear-bearing version over the brass-bearing TMICM when low friction and precise travel outweigh the need for torsional stiffness. The variable air cushion is essential for high-speed moves up to 500 mm/s, as it prevents end-of-stroke shock without acting as a brake.
This 75 mm stroke unit uses a 1/8" port and a Ø10 mm rod. The -S magnet enables CMSG, DMSG and EMSG switches for position feedback. If your payload must stay put during an air loss event, add an external rod lock or pilot check valve, because the guide frame allows the piston to drift.

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 TMICL25X75S 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, with a theoretical max of 50 kgf at 1.0 MPa. However, thrust is not the load limit—you must confirm the actual allowable payload from the TMI/TMIC load-offset curves based on your specific mounting distance.
It features a variable air cushion at both ends that decelerates the piston near stroke ends for smooth motion; it is not a lock or brake. The -S suffix means it has a built-in magnet for CMSG, DMSG and EMSG switches. The linear bearings provide low friction for vertical push-up moves.
