Seizures (gear)

They appear in case of recurrent breakdown of the lubricating film.

When seizing factor is too high (hertz pressure times year) and exceeds the limit of the lubricant resistance used, the first metal to metal contacts appear.

The seizures can be localized (surface defect and scope), on slide areas only (lubrication default), or finally on the entire surface (seizing that generated an increase in temperature). In this case, a shutdown of the installation, cleaning or reprofiling are needed.
