Airtac TMIC Guided Cylinder with Guide Unit TMICL20X50S
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICL20X50S is a genuine guide-frame (guided) pneumatic cylinder — a Ø20mm 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 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 TMICL20X50S
Built around a 20mm bore, the AirTAC TMICL20X50S is a double-acting guide-frame cylinder that integrates an MIC mini unit into a twin-rod aluminium slide. It runs on linear bearings to deliver low-friction, high-precision travel, making it an excellent choice for vertical push-up applications. The integrated piston magnet (-S) directly supports CMSG, DMSG, and EMSG position switches.
A needle-set variable air cushion at both ends absorbs high-speed shock for smooth, quiet stops, while the frame handles side load and torque. Delivering 157N of push force at 0.5MPa via a 1/8" port, it provides a safe working thrust of roughly 94N. This translates to pushing about 8kg vertically with a 2:1 safety margin, load curve permitting. Remember that thrust does not dictate the guided load limit—always verify allowable load against the offset distance using the official load curves.

|---|---|
| Fluid | Air (filtered by 40µm element) |

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 (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | 185 N |
| Max (@1.0 MPa) | 32 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 TMICL20X50S Is Used
Vertical Lift Stations
Pushing roughly 8kg vertically with a 2:1 margin, the linear bearings provide the precise, low-friction motion needed for smooth upward actuation in compact lifting rigs.
High-Speed Transfer
Absorbing kinetic energy at rapid cycle speeds, the dual variable air cushions ensure quiet, square stops without rebound when shifting lightweight trays between belts.
Guided Pressing
The twin-rod frame resists side load and torque during downward pressing or seating tasks, keeping the 8mm rod true while delivering 157N of thrust at 0.5MPa.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICL20X50S the Right Cylinder?
When sizing this 20mm bore unit, compare it directly with its siblings: step down to a 16mm version for lighter 100.5N push tasks, or move up to a 25mm frame for 245.3N if you need more force. Choose this TMICL linear-bearing build over the brass-bearing TMICM when smooth, accurate travel and low friction matter more than torsional stiffness. The variable air cushion is essential for high-speed moves or heavy payloads, preventing end-of-stroke impact.
Because the load capacity falls as the mass sits further from the plate, you must size from the load-offset curve rather than relying on the 32kgf theoretical maximum. This 50mm stroke, 1/8" ported model arrives ready to mount, and the included -S magnet means it is fully prepared for CMSG, DMSG, or EMSG sensors right out of the box.

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 TMICL20X50S FAQ
This 20mm bore cylinder delivers 157N push and 131.9N pull at 0.5MPa, rising to 219.8N push and 184.7N pull at 0.7MPa, with a theoretical maximum of 32kgf at 1.0MPa. However, thrust is not the guided-load limit; the actual load it can carry depends entirely on the load-offset distance and must be verified using the TMI/TMIC maximum-load curves.
It uses linear bearings for high precision and low friction, making it ideal for vertical push-up moves. The variable air cushion at both ends only decelerates the piston near stroke end to absorb shock—it is not a lock or brake. On air loss, the piston will drift; for position holding, you must fit an external rod lock or pilot check valve. The -S magnet enables CMSG, DMSG, and EMSG sensors.
