14 Shaft and Housing Design
14 Shaft and Housing Design 14 1 Fixing of bearings When fixing a bearing in position on a shaft or in a housing there are many instances where the interference fit alone is not enough to hold the bearing in place Bearing ring must be fixed in place by various methods so they do not axially move when placed under load
Calculating Grease Quantity Frequency
If the bearing is mounted on a vertical shaft the grease has a tendency to run out of the bearing quicker thus needing to be replenished more often When the bearing is subjected to vibration it causes the oil in the grease to separate from the thickener allowing it to drain away from where it is needed much faster Therefore these two
