Airtac TMIC Guided Cylinder with Guide Unit TMICM25X50
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICM25X50 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 TMICM25X50
Built around a 25 mm bore, the TMICM25X50 guide-frame cylinder pairs a double-acting MIC unit with a twin-rod aluminium slide running on brass bearings. It pushes 245.3 N and pulls 206.1 N at 0.5 MPa, peaking at a theoretical 50 kgf. The brass bearing delivers high torsional stiffness, making it the right pick when your load twists the tool or pushes sideways. A needle-set variable air cushion at both ends soaks up high-speed shock for smooth, square motion.
This 50 mm stroke unit uses a 1/8" port and a 10 mm rod. Because it lacks the -S magnet, this SKU cannot take a magnetic switch. Remember that thrust is not the load limit; the allowable load falls as the distance from the plate grows, so size from the load-offset curve. Factoring a 60% safety margin yields a safe working thrust of roughly 147 N, or about 12.5 kg of vertical push with a 2:1 factor, 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 TMICM25X50 Is Used
High-Speed Diverting
Uses the 245.3 N thrust to push heavy cartons sideways on a conveyor, relying on the brass bearings to resist the twisting impact during rapid 50 mm strokes.
Vertical Stamping
Drives a short-stroke marking head with safe working thrust around 147 N, while the needle air cushion decelerates the 10 mm rod smoothly at the bottom of the hit.
Flap Folding
Folds heavy packaging flaps under side load, where the twin-rod guide frame maintains square alignment and the brass bearings shrug off radial forces.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICM25X50 the Right Cylinder?
If 245.3 N of push at 0.5 MPa is more than you need, step down to the TMICM20X50 which provides 157.0 N; if you need more force, this 25 mm bore is the largest cushioned option in the series. Choose this brass-bearing M variant over the linear TMICL when your application imposes high torsional loads rather than requiring low-friction precision. The variable air cushion matters most when driving heavy loads at high speeds, though it only decelerates near stroke end and will not hold position on air loss.
Always verify the actual permissible payload against the TMI/TMIC maximum-load curves based on your specific load-offset distance. Since this specific SKU is not built with a magnet, it cannot accept CMSG, DMSG, or EMSG sensors. For position feedback, select the -S variant, and for holding a load on air loss, install an external rod lock or pilot check valve.

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 TMICM25X50 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. The theoretical maximum force is 50 kgf at 1.0 MPa. Remember that thrust is not the load limit; the actual payload it can carry depends on the load-offset distance and must be read from the TMI/TMIC maximum-load curves.
This specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors. You need the -S variant for switches. It uses brass bearings for high torsional stiffness against side loads, and a variable air cushion at both ends to decelerate motion near stroke end. The cushion is not a lock or brake.
