Specification Charts & Notes

Thrust or torque is a function of speed. The values given above are maximums. These values cannot both be achieved simultaneously (i.e. at maximum speed, the unit will not produce maximum thrust).

Other

<ol class="ml-4"> <li>The suffix "S" designates a short unit. Manual control and LED indicators have been sacrificed on these units in favour of reduced length. All other specifications are identical to the standard unit.</li> <li>T-LA actuators don't require hold current to maintain their position.</li> <li>The T-LA is more delicate and has a limited lifetime compared to the T-NA08. See the image below for a lifetime vs thrust comparison.</li> </ol>

Note that the failure mode of T-LA devices is grease contamination by wear particles which effectively clog the lead-nut, although the lead screw and lead-nut remain in healthy condition. Extending the lead screw, cleaning it, and regreasing it with a silicon based grease effectively solves the problem; however, this may not be feasible in all applications.
