Airtac TMIC Guided Cylinder with Guide Unit TMICL25X150
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICL25X150 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 150mm stroke stays true, giving you a ready-to-mount linear slide without a separate guide.

About the Airtac TMIC Guided Cylinder with Guide Unit TMICL25X150
Built around an MIC mini cylinder housed in a twin-rod aluminium guide frame, the TMICL25X150 uses linear bearings to deliver smooth, accurate travel at high speeds. A needle-set variable air cushion at both ends soaks up end-of-stroke shock, ensuring quiet, square motion while the frame absorbs side load and torque. This 25 mm bore, 150 mm stroke double-acting slide runs on a 1/8" port and achieves a push force of 245.3 N at 0.5 MPa.
Because the guide frame dictates capacity, the allowable load falls as the mass sits further from the plate, so always size from the load-offset curve rather than the thrust rating. For a 2:1 safety margin, this unit pushes about 12.5 kg vertically, load curve permitting, yielding a safe working thrust of roughly 147 N. Note that this specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG position switches without moving to the -S variant.

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 TMICL25X150 Is Used
Vertical Push-Up Assembly
Leveraging the low-friction linear bearings, this 25 mm bore cylinder smoothly lifts 12.5 kg tooling heads in a 2:1 safety margin, using the variable air cushion to soften the top impact.
High-Speed Diverting
With 245.3 N of thrust at 0.5 MPa, the twin-rod frame precisely diverts heavier packages on a conveyor while maintaining square, shock-free motion at cycle speeds up to 500 mm/s.
Multi-Axis Machining Feed
The rigid guide frame handles offset loads during parts feeding, keeping the 10 mm rod true. The needle-set cushion decelerates the 150 mm stroke smoothly to protect delicate workpieces.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICL25X150 the Right Cylinder?
When sizing this 25 mm bore unit, compare it directly against the smaller TMICL20X150, which provides 157.0 N of push at 0.5 MPa. If your application requires less force, the 20 mm frame offers a lighter footprint, but this 25 mm model is the largest standard bore available, delivering a maximum theoretical output of 50 kgf at 1.0 MPa. Choose this linear-bearing (L) configuration over the brass-bearing TMICM when low friction and high precision are more critical than torsional stiffness.
The variable air cushion is essential for high-speed moves or heavy payloads, decelerating the piston near stroke end to prevent harsh impacts. Remember that the cushion only slows the piston, it does not function as a lock or brake, so you will need an external rod lock or pilot check valve to hold position on air loss. Finally, because this exact SKU has no magnet, you must select a TMICL25X150-S model if your control system requires sensor feedback.
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 TMICL25X150 FAQ
This double-acting 25 mm bore cylinder delivers a push of 245.3 N and a pull of 206.1 N at 0.5 MPa, increasing to a push of 343.4 N at 0.7 MPa, with a theoretical maximum of 50 kgf at 1.0 MPa. However, thrust is not the load limit, the allowable load depends entirely on the load-offset distance and must be verified using the official TMI/TMIC maximum-load curves.
This specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG switches, you would need the TMICL25X150-S variant for sensor feedback. Mechanically, the linear bearings provide high precision and low friction ideal for vertical push-up moves, while the needle-set variable air cushion at both ends absorbs high-speed shock for smooth deceleration.
