GEZ..ES Open & GEZ..ES-2RS Sealed Note

N/A RADIAL STATIC LOAD CAPACITY
These loads are the maximum safe operating loads for stationary applications, and assumes a sufficiently rigid housing and shaft. The radial static load capacity provides a 1.5 factor of safety against static fracture.
LUBRICATION
Bearings should only be used as delivered for static applications. For dynamic applications, a lithium-based grease with EP and MOS2 additives is especially suitable. Lubricants of this type are recommended for operating temperatures between -40° F and + 250° F (-40° C and +121° C). For operating temperatures outside of this range, consult lubricant manufacturer.
Bearings should be adequately lubricated before installation, and relubricated at suitable intervals based on application demands. Demand factors include load and load direction, misalignment angle and frequency, ambient temperature and contamination level.
