Airtac TMIC Guided Cylinder with Guide Unit TMICL25X50S
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICL25X50S 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 50mm stroke stays true, giving you a ready-to-mount linear slide without a separate guide.

About the Airtac TMIC Guided Cylinder with Guide Unit TMICL25X50S
Built around a 25 mm bore MIC unit, the TMICL25X50S guide-frame cylinder delivers 245.3 N push and 206.1 N pull at 0.5 MPa, stepping up to 343.4 N push at 0.7 MPa. The twin-rod aluminium frame runs on linear bearings to carry side load and torque, keeping the Ø10 mm rod true while providing low-friction, high-precision travel. A needle-set variable air cushion at both ends absorbs high-speed shock for smooth, quiet deceleration near stroke end.
Because the frame dictates what you can lift, always size the allowable load from the TMI/TMIC maximum-load curves rather than relying on thrust alone. For vertical push-up moves, expect about 12.5 kg of safe lifting force with a 2:1 margin, load curve permitting. This -S SKU includes a piston magnet for position sensing and uses a 1/8" port. Note that the cushion only decelerates the stroke; it is not a lock, so add an external rod lock or pilot check valve if you must hold a load on air loss.

| Acting type | Double acting |
|---|---|
| Fluid | Air (filtered by 40µm element) |
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |

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 TMICL25X50S Is Used
Vertical Press Fit
Pushes down with 245.3 N at 0.5 MPa to seat bearings. The linear bearings keep the rod square under offset, while the air cushion prevents harsh end impacts.
Heavy Transfer Divert
Handles robust side loads when redirecting heavier items on a line. The twin-rod frame absorbs torque, and the -S magnet tracks position for sorting.
High-Speed Carton Flap
Closes heavy carton flaps rapidly. The needle-set cushion damps the 30-500 mm/s travel speed for quiet, square stops without rebound.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICL25X50S the Right Cylinder?
When sizing this 25 mm unit, step down to the TMICL20X50S (157.0 N push at 0.5 MPa) if your side load is light, or step up to a larger non-guided cylinder if you need raw thrust beyond 343.4 N at 0.7 MPa. Choose these linear bearings over the brass-bearing TMICM variant when smooth, accurate travel and low friction matter more than torsional stiffness. The dual air cushions are essential for high-speed moves, letting you dial in the end-of-stroke deceleration.
Always verify your payload against the load-offset curve, as the allowable weight drops the further the load sits from the plate. This -S model supports CMSG, DMSG and EMSG sensors via its built-in magnet. Remember that the guide frame resists side load but does not hold position on air loss, so factor in an external rod lock for vertical safety.

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 TMICL25X50S FAQ
It delivers 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 max of 50 kgf at 1.0 MPa. However, thrust is not the guided-load limit; the allowable load depends on the load-offset distance and must be confirmed from the TMI/TMIC maximum-load curves.
Yes, the -S suffix means it has a built-in piston magnet for CMSG, DMSG or EMSG switches. It uses a needle-set variable air cushion at both ends to decelerate high-speed travel smoothly. The cushion only softens the end-of-stroke impact; it is not a brake and will not hold the load on air loss.
