The 6306-ZZ deep groove ball bearing is a 30 mm bore, single-row sealed bearing widely used in medium-duty motors, gearboxes, conveyor drives, agricultural shafts, and three-phase pump assemblies. This pack of 5 is ideal for maintenance kits and small-batch repairs. Metal shields on both sides keep dust and debris out of the raceway while permitting higher operating speeds than rubber-sealed (2RS) variants.
