1.1.9 ICR Side Load Considerations
Rod screw actuators are designed to push guided and supported loads and are not
designed for applications that require significant side loading. Contact Tolomatic for
details regarding side loading capabilities.
1.1.10 Brake Considerations
An unpowered ICR will require a brake to maintain its position if the force on the
actuator exceeds: BN02 screw - 7.5 lbf (33.4 N); BN05 screw - 12.5 lbf (55.6 N)
A brake can be used with the actuator to keep it from backdriving, typically in
vertical applications. A brake may be used for safety reasons or for energy savings
allowing the actuator to hold position when unpowered. Add
SAB
to the ordering
code for the optional Spring-Applied / Electronically-Released Brake. (not available
for service part ordering)
NOTE: The optional Spring-Applied / Electronically-Released Brake requires 24V
power. It has a input current rating of 0.414 Amps.
