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).

Bearing Lifetime

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. For more detailed information, please consult the Installation Precautions.

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.
T-LA actuators don't require hold current to maintain their position.
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.
