NSK Wide Series Angular Contact ball bearings for Machine Tool main spindles of Machining centres and Lathes. With the wider Series there is more space retention for grease, thus allowing both the amount of grease and the amount of prepacked grease retained to be higher than the standard series. This also allows an extension of grease life even though the run-in period is the same as that for a conventional bearing.
