Airtac TMIC Guided Cylinder with Guide Unit TMICM25X50S
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICM25X50S 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 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 TMICM25X50S
Built around a 25 mm bore, this twin-rod guide-frame unit delivers 245.3 N of push force at 0.5 MPa while shrugging off radial loads through its brass bearings. The integrated variable air cushion at both ends soaks up high-speed shock, ensuring smooth and square motion without side-play. It operates at 30-500 mm/s, taking a 1/8" air supply.
Because the frame carries the torque, the rod stays true even when the tool twists. The -S suffix equips the piston with a magnet for CMSG, DMSG, or EMSG position switches. Remember that thrust is not the load limit; the actual payload you can mount depends on the distance from the plate and must be verified from the load-offset curve. For a safe working setup, expect about 147 N of usable thrust, which pushes roughly 12.5 kg vertically with a 2:1 margin, load permitting.

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 TMICM25X50S Is Used
High-Speed Z-Axis Stamping
Uses the 245.3 N thrust at 0.5 MPa to drive a short 50 mm stamping stroke, relying on the brass bearings to resist tool torsion and the air cushion to absorb end-of-stroke shock.
Carton Flap Folding
Pushes heavy cardboard flaps rapidly with about 12.5 kg of vertical force, where the twin-rod guide frame prevents binding from off-center packaging resistance.
Inline Product Diverting
Handles lateral diverting of heavier items at speed, using the needle-set cushion to bring the 50 mm stroke to a quiet, square stop without bouncing.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICM25X50S the Right Cylinder?
When sizing this 25 mm bore unit against the family, step down to the 20 mm version if your application only needs 157.0 N of push at 0.5 MPa, or look to related non-cushioned TMIM types for lighter, low-speed tasks. Choose this brass-bearing build over the linear-bearing TMICL when your load pushes sideways or induces high torsional stress. The variable air cushion is essential here for heavy or fast-moving loads, decelerating the stroke cleanly at the end caps.
Always confirm your allowable payload from the maximum load curves based on your specific load-offset distance, as exceeding the offset will bind the rods. This specific SKU includes the -S magnet, so it is fully ready for CMSG, DMSG, or EMSG sensors; a non-S SKU cannot accept them. If you need to hold position on air loss, add an external rod lock or pilot check valve, as the cushion only decelerates and never locks.

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 TMICM25X50S 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. However, thrust is not the guided-load limit; the actual payload you can carry depends on the load-offset distance and must be read from the TMI/TMIC maximum-load curves.
Yes, the -S suffix means a magnet is built-in, allowing you to mount CMSG, DMSG, or EMSG switches for detection. The brass bearings provide high torsional stiffness for radial loads, but the cylinder does not hold position on air loss—the piston will drift. The variable air cushion only decelerates near the stroke end and acts as a brake.
