Airtac TMIC Guided Cylinder with Guide Unit TMICL25X50
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICL25X50 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 TMICL25X50
Built around a 25 mm bore MIC mini cylinder, the TMICL25X50 is a double-acting guide-frame slide running on linear bearings. A needle-set variable air cushion at both ends soaks up high-speed shock for smooth, square stops, while the twin-rod aluminium frame carries the side load and torque to keep the Ø10 mm rod true. It pushes with 245.3 N and pulls with 206.1 N at 0.5 MPa, peaking at a 50 kgf theoretical max at 1.0 MPa.
The linear bearings give low friction and high precision, making this unit the pick for vertical push-up moves and smooth, accurate travel. For a safe working thrust, plan around 147 N (about 60 percent of the 0.5 MPa push figure), or roughly 12.5 kg of vertical push with a 2:1 margin, load curve permitting. Remember the load it can carry falls as the weight sits further from the plate, so always size from the TMI/TMIC load-offset curve rather than the thrust alone. This non-magnet SKU uses a 1/8" port and cannot take a sensor; order the -S variant for CMSG, DMSG or EMSG switches.
Airtac TMIC Guided Cylinder with Guide Unit TMICL25X50 Technical Specifications

| Acting type | Double acting |
|---|---|
| Fluid | Air (filtered by 40µm element) |
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |

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 TMICL25X50 Is Used
Vertical Press Push-Up
Uses the 245.3 N thrust at 0.5 MPa for downward pressing tasks, with linear bearings ensuring smooth, low-friction vertical travel and the air cushion softening the end-of-stroke impact.
High-Speed Transfer Diverter
Ideal for rapidly diverting heavier items on a line, where the twin-rod guide frame resists torsional loads and the needle-set cushion absorbs the shock of fast 50 mm strokes.
Precision Parts Lift
Lifts components smoothly using the high-precision linear bearing guide, relying on the frame to keep the load square without inducing side-load wear on the cylinder rod.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICL25X50 the Right Cylinder?
If 245.3 N of push at 0.5 MPa is more than you need, step down to the TMICL20X50 which delivers 157.0 N; if you need more force, this 25 mm bore is the largest cushioned size in the range. Choose these linear bearings over the brass-bearing TMICM when friction and accuracy matter more than torsional stiffness. The variable air cushion is essential for high-speed moves or heavy loads, decelerating the piston near stroke end to prevent hard impacts. Always verify your allowable load against the load-offset curve, and match your mounting and magnet needs: this base SKU lacks a magnet, so specify the -S option if you need position sensing.
Quick checklist
- ✓ Required thrust at your working pressure
- ✓ Load and offset within the load curve
- ✓ Bearing: brass (torque) vs linear (precision)
- ✓ Stroke and mounting space
- ✓ Magnet (-S) for sensors?
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 TMICL25X50 FAQ
This 25 mm bore cylinder pushes at 245.3 N and pulls at 206.1 N at 0.5 MPa, pushes 343.4 N at 0.7 MPa, and has a theoretical max of 50 kgf at 1.0 MPa. Thrust is not the load limit, however: the allowable load depends on the load-offset distance and must be read from the TMI/TMIC maximum-load curves.
This specific SKU lacks a magnet and cannot take a sensor; you must order the -S variant to use CMSG, DMSG or EMSG switches. The variable air cushion at both ends uses a needle valve to decelerate the piston near stroke end for smooth, quiet motion, but it is not a lock or brake and will not hold the load on air loss.
