3 Piece Thrust Bearings Open Type with Flat Washers
These bearings are designed so that when one ring turns, the other remains stationary. Some have a larger bore on one side allowing a shaft with no steps to pass through. Others will require a stepped shaft as they have the same bore on both races. Some have a reduced size OD on one race allowing it to sit into an unstepped housing bore, whilst others will require a stepped housing to allow one ring to rotate. Please be sure to take note of the figures shown for ID and OD of both races to ensure you select the correct bearing. This category may be available in the new MBA online store at
