The bearings should be greased slightly approximately every 100 hours of operation with the recommended lubricant.
Over greasing will cause the bearings to overheat
BEARING REMOVAL AND INSTALLATION
The bearing cartridge assemblies which support the ends of the concentric shafts are made up of a flanged cartridge
or housing and a roller bearing. The bearing is a light press fit in the cartridge and can be installed or removed on an
arbor press. The bearing is bottomed against a flange of the cartridge with no shims or clearance allowance required.
The bearing bore fits the concentric shaft loosely and this slide-on fit makes cartridge removal and installation easy.
The thrust clearances are pre-established by factory machining and no shimming or adjusting of the cartridge
assembly to the housing is required at installation.
The clearance in roller bearings is checked by pressing the top roller as far inward as possible and passing a feeler
gauge back and forth between it and the outer race. If this is done when the vibrator is hot from operation the
clearance will more nearly reflect the actual operating condition.
IMPORTANT It is absolutely necessary that the housing and all parts of the vibrator assembly be
completely cleaned and kept free of dirt and contaminants in order to avoid rapid failure for new
bearings. If there is a probability of contamination, Improved working conditions should be
arranged before the job is attempted. Solvents are recommended for cleaning and flushing.
