Figures are the highest published for each series and are not always measured the same way. A higher figure is not automatically a better choice: mounting, duty cycle, feedback, connectors and approvals matter too. An engineer will check the fit against your application before recommending anything.
Typical applications
What an integrated-motor actuator is
An integrated-motor actuator combines the servo motor and the screw in one body, often with the motor rotor driving the screw or nut directly instead of through a coupling or belt. Many use an inverted roller screw inside a hollow rotor for a very compact, stiff design. Some versions also integrate the servo drive and position controller, so the actuator needs only power and a command or fieldbus connection. The result is a shorter, sealed unit with fewer parts to align.
When engineers choose an integrated-motor actuator
Choose an integrated-motor actuator when space is tight, a clean sealed package is wanted, or decentralised control reduces cabinet size and cabling. It suits welding guns, robot cells and hygienic plant. The trade-offs are flexibility and service: the motor cannot be changed independently, thermal limits are shared and repairs may mean replacing the whole unit. A separate motor and actuator lets you change motor size or brand later and is often easier to source as spare parts.
How to specify the Exlar Tritex II T2X (AC linear actuator)
Send these with your enquiry and an engineer can confirm the right Tritex II T2X (AC linear actuator) variant or an equivalent:
- Force, peak and continuous (N)
- Stroke (mm) and speed (mm/s)
- Supply voltage: mains AC or low-voltage DC (V)
- Control interface: analogue, pulse, Modbus or industrial Ethernet
- Feedback and absolute position needs
- Duty cycle and ambient temperature (°C)
- Sealing and cleaning requirements (IP code)
Common mistakes to avoid
- Overlooking heat build-up when motor and screw share one housing
- Assuming any drive will run it, when integrated units may need a matched drive
- Not checking cable routing and connector orientation on the machine
- Forgetting spare strategy when the whole unit is one part
Exlar Tritex II T2X (AC linear actuator): frequently asked questions
Can you help replace Exlar Tritex II T2X (AC linear actuator) or source the original?
Send the full model code, quantity and required date. Our engineers can check original-part availability and assess suitable alternatives, including supply-network options where appropriate. We confirm compatibility and any changes needed before recommending a replacement.
What is the Exlar Tritex II T2X (AC linear actuator)?
Roller-screw actuator with motor, servo drive and position controller all built in, running from single-phase AC mains and accepting analogue, Modbus or optional industrial Ethernet commands. Published series figures include temperature -20 °C, temperature 65 °C, force 24,020 N, continuous force 14,341 N. It is made by Curtiss-Wright Actuation Group; Specify Motion can help source it or propose an equivalent.
Who makes the Exlar Tritex II T2X (AC linear actuator)?
The Exlar Tritex II T2X (AC linear actuator) is made by Exlar (Curtiss-Wright Actuation Group) and is listed here for engineers comparing options. Specify Motion is not affiliated with Curtiss-Wright Actuation Group; brand names are used only to identify the product.
What is the temperature of the Exlar Tritex II T2X (AC linear actuator)?
The published series minimum temperature is -20 °C. Individual models and sizes in the Tritex II T2X (AC linear actuator) range vary, so check the exact variant against your duty cycle, mounting and environment, or ask our engineers to confirm the right size for you.
Is there an alternative to the Exlar Tritex II T2X (AC linear actuator)?
We can assess suitable replacement options. On published figures, Tolomatic IMA Integrated Motor Actuator and Motion Control Products SRB Linear Servo Actuator are options to assess from our supply network. An engineer confirms the fit against your application before recommending anything.
What are the advantages of an integrated motor actuator?
Combining motor and screw removes couplings, belts and the alignment that goes with them, so the actuator is shorter, stiffer and easier to seal. Versions with built-in drives also reduce cabinet space and cable runs. The downside is less flexibility for changing motor size and a larger, more expensive spare part.
Can an integrated actuator be controlled from a PLC?
Yes. Versions with built-in drives typically accept analogue, pulse and direction, discrete I/O or industrial Ethernet commands from a PLC. Versions without a drive need a compatible servo drive, often from a matched range. State the controller and network protocol at the outset so the right variant is selected.
