what temperature is too high for a jaw crusher bearing
Double Roll Crushers. Double Roll Crushers typically follow a primary or secondary crusher and are used for secondary and tertiary reduction of various minerals, such as ROM coal, clean coal, limestone, gypsum, trona, shale, bauxite, oil shale, coke, salt, .Normal motor bearing operating temperatures range from 140° to 160°F. As in all bearing applications, this measurement should be taken at the bearing outer ring. If the outer ring is inaccessible, take the measurement at the housing and add 15° to 20°F to estimate the correct bearing temperature.
