Airtac TMIC Guided Cylinder with Guide Unit TMICL25X125S
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICL25X125S 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 125mm stroke stays true, giving you a ready-to-mount linear slide without a separate guide.

About the Airtac TMIC Guided Cylinder with Guide Unit TMICL25X125S
Twin-rod aluminium construction houses an MIC mini cylinder to form the TMICL25X125S guided slide. Needle-set variable air cushions at both ends absorb high-speed shock, keeping motion square and quiet, while linear bearings provide low-friction, high-precision travel ideal for vertical push-up moves.
Delivering 245.3 N push and 206.1 N pull at 0.5 MPa (343.4 N push at 0.7 MPa, 50 kgf max theoretical at 1.0 MPa) through a 1/8" port, this double-acting unit yields a safe working thrust around 147 N. It pushes about 12.5 kg vertically with a 2:1 margin, load curve permitting. The frame carries side load and torque, but remember thrust is not the load limit; always confirm allowable load from the offset curves.

| Acting type | Double acting |
|---|---|
| Fluid | Air (filtered by 40µm element) |

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 TMICL25X125S Is Used
Vertical Push-Up Pressing
Leverages the 245.3 N thrust and low-friction linear bearings to push components into place smoothly, with the air cushion decelerating the 125 mm stroke to prevent hard impact.
High-Speed Diverting
Handles rapid lateral sorting of heavier items where the twin-rod frame resists torsional load, while the -S magnet confirms end-of-stroke position via DMSG sensors.
Precision Carton Loading
Pushes packaged goods precisely into cases using the accurate linear travel, relying on the needle-set cushion to absorb the shock of moving mass at cycle end.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICL25X125S the Right Cylinder?
When sizing this 25 mm bore unit, step down to a TMICL20X125S for lighter loads (157.0 N push @0.5 MPa) or step up if you need more force, though 25 mm is the largest cushioned variant in this series. Choose these linear bearings over the brass-bearing TMICM when smooth, accurate travel and low friction matter more than torsional stiffness. The variable air cushion is essential for high-speed or heavy moving masses to prevent end-of-stroke impact.
Because allowable load falls as the distance from the mounting plate increases, always size from the load-offset curve rather than the thrust figure. The -S suffix provides a built-in magnet for CMSG, DMSG, or EMSG sensors. Note the guide frame resists side load but does not hold position on air loss; add an external rod lock or pilot check valve if you need braking.
Quick checklist

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 TMICL25X125S FAQ
This double-acting 25 mm bore cylinder with a 1/8" port provides 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push at 0.7 MPa, and a theoretical max of 50 kgf at 1.0 MPa. Thrust is not the guided-load limit; the maximum load depends on the load-offset distance and must be verified from the TMI/TMIC maximum-load curves.
Linear bearings provide high precision and low friction, ideal for vertical push-up moves, while the variable air cushion at both ends decelerates the piston near stroke ends to absorb high-speed shock. The cushion is not a brake; the cylinder drifts on air loss. The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG sensors.
