Notes on extreme operating temperatures

The components affected by temperature in the ZeroErr eRob rotary actuator include chips and grease. The built-in chips all meet the operating temperature requirement of -40°C. Grease will have the effect of increasing viscous resistance at low temperatures. The viscosity of ordinary grease increases significantly at low temperatures and may not operate properly. The suffix C in our customized models represents the use of special low-temperature grease, which has a smaller viscosity increase at low temperatures. If you need to test whether the eRob works normally in a working environment of -40°C, please conduct it at a professional third-party accreditation agency. Please do not conduct tests at -40°C in a self-built test environment.

There are several reasons for this:

1.Due to temperature control accuracy issues, the actual temperature may be lower than -40°C. If the actual temperature is -41°C, the chip may not work properly.

2. The problem of irregular experimental operation, for example, the air outlet of the equipment may produce a local temperature environment of -50°C, resulting in failure to work normally.

3. Alternating low and high temperatures lead to humidity problems. During temperature fluctuations, condensation may form and cause actuator failure. Even with humidity control in the chamber, condensation may still form inside the actuator during actual operation.

Please note that products tested for high and low temperature are not covered by the warranty.

Therefore, the operating temperature of all the components in our actuators can meet the value of -40°C, but we do not guarantee that the actuators can work at -40°C, please choose carefully.

If you need professional high and low temperature testing, please contact us without hesitation.
