Airtac TMIC Guided Cylinder with Guide Unit TMICM25X75S
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICM25X75S is a genuine guide-frame (guided) pneumatic cylinder — a Ø25mm double-acting MI mini cylinder built into a twin-rod guide unit running on brass 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 TMICM25X75S
Built around a 25 mm bore, this twin-rod guide frame pairs an MIC round-body cylinder with brass bearings to deliver true linear motion. It pushes with 245.3 N and pulls with 206.1 N at 0.5 MPa, while a needle-set variable air cushion at each end soaks up high-speed end-of-stroke shock for quiet, square stops. The brass bearing design yields high torsional stiffness, making it the right pick when the tooling twists or pushes sideways.
Remember that thrust does not set the payload limit; the allowable load falls as the distance from the guide plate increases, so always size from the TMI/TMIC load-offset curve. For a practical margin, expect a safe working thrust around 147 N (60 percent of the 0.5 MPa push), which lifts about 12.5 kg vertically with a 2:1 safety factor, load curve permitting. This unit has a 10 mm rod, a 1/8" port, and the -S piston magnet for position sensing.

|---|---|
| Fluid | Air (filtered by 40µm element) |
| Operating pressure | 0.15 – 1.0 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 TMICM25X75S Is Used
Vertical Stamping Press
Drives a 12 kg stamping head downward at speed, relying on the brass bearings to resist off-center twisting and the air cushions to prevent harsh bottoming impact.
Heavy Diverter Gate
Pushes loaded pallets sideways using the 245.3 N thrust at 0.5 MPa, with the twin-rod frame keeping the pusher face square under radial load.
Carton Flap Folder
Folds heavy cardboard flaps at high cycle rates, using the needle-set cushions to decelerate the 75 mm stroke smoothly without bouncing the tool.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICM25X75S the Right Cylinder?
If 245.3 N of push at 0.5 MPa is excessive, step down to the TMICM20X75S which supplies 157.0 N. If you need more force, there is no larger standard TMICM bore, so you would look outside this family. Choose this brass-bearing (M) build over the linear-bearing (L) variant when your application applies heavy radial loads or twisting torque to the tooling.
The variable air cushion is essential for high-speed moves (up to 500 mm/s) where a fixed rubber bumper would bounce or wear out. The -S suffix means a magnet is installed for CMSG, DMSG, or EMSG switches; without that S suffix, the SKU cannot take a sensor. Note that the cushion only decelerates the piston near stroke end—it is not a brake. For holding position on air loss, add an external rod lock or pilot check valve.
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 TMICM25X75S 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. The bore uses a 1/8" port. Thrust is not the guided-load limit: the actual payload it can carry depends on the load-offset distance and must be verified from the TMI/TMIC maximum-load curves.
The brass bearings provide high torsional stiffness to handle radial loads and twisting torque, while the needle-set variable air cushions at both ends absorb high-speed end-of-stroke shock for smooth deceleration. The -S suffix equips it with a magnet for CMSG, DMSG, or EMSG sensors. The cushion only decelerates and is not a lock; on air loss the piston drifts, so use an external rod lock or pilot check valve to hold a load.
