Airtac TMIC Guided Cylinder with Guide Unit TMICM25X200S
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICM25X200S 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 200mm stroke stays true, giving you a ready-to-mount linear slide without a separate guide.

About the Airtac TMIC Guided Cylinder with Guide Unit TMICM25X200S
Twin brass bearings and a needle-set air cushion at each end define this guide-frame slide, built around a 25 mm bore double-acting MIC cylinder. The frame absorbs torque and radial load while the variable cushions soak up high-speed end-of-stroke shock for smooth, quiet motion. A 200 mm stroke falls well inside the 250 mm standard limit, and the -S suffix adds a piston magnet for position sensing.
This bore 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 50 kgf theoretical maximum at 1.0 MPa. For reliable operation, a safe working thrust is roughly 147 N, meaning it pushes about 12.5 kg vertically with a 2:1 margin, load curve permitting. The 1/8" port feeds the air supply, but remember the actual payload limit depends on the load-offset distance, so always confirm the allowable weight from the datasheet curves rather than relying on thrust alone.

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 TMICM25X200S Is Used
Pallet Diverting Gate
Shifts heavy pallets sideways at speed; the brass bearings resist the twisting torque while the air cushion halts the 200 mm stroke smoothly without shock.
Carton Flap Folding
Drives a folding arm on a fast packaging line, using the 245.3 N push force to overcome cardboard stiffness while the twin rods keep the tool square.
Vertical Lift Stopper
Acts as a high-speed stopper for totes, absorbing the impact through the needle-set cushion and handling the downward radial load on the brass guides.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICM25X200S the Right Cylinder?
When sizing this 25 mm unit against the family, stepping down to the TMICM20X200S drops the 0.5 MPa push force to 157 N, whereas this model provides 245.3 N for heavier tooling. If you need less friction than brass provides, the TMICL25X200S sibling uses linear bearings for precision, while the bumper-equipped TMIM25 offers a lower-cost alternative when end cushions are not strictly required. Keep the brass variant when the load twists or pushes sideways.
The variable air cushion matters most at high speeds within the 30-500 mm/s guided range or when moving heavy masses, as it decelerates the piston smoothly without slamming. Because the frame resists side load but does not lock the stroke, an external rod lock or pilot check valve is required to hold position on air loss. Finally, ensure you specify the -S magnet option if you need to mount CMSG, DMSG, or EMSG switches, as non-S SKUs cannot accept 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 TMICM25X200S FAQ
At 0.5 MPa it provides 245.3 N push and 206.1 N pull, increasing 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 actual payload capacity falls as the load sits further from the plate, so you must verify the allowable weight from the load-offset curve.
The brass bearings provide high torsional stiffness to handle radial loads, while the variable air cushion at both ends uses a needle valve to decelerate the piston near stroke end for smooth motion. The cushion only slows the stroke and does not act as a lock or brake; the piston will drift on air loss, so use an external rod lock to hold position. The -S magnet enables CMSG, DMSG, or EMSG sensors for end-of-stroke detection.
