A deep groove ball bearing carries radial load with moderate thrust in either direction and needs no particular mounting orientation. P4S precision holds bore, outside diameter, width and runout to close limits, giving true running and low vibration at speed.
Application Types: Precision spindles; precision gearboxes; instrument and test-rig drives; grinding and boring heads.
Unit Quantity: 1 Pc
ISO base number 6018. A commercial-grade 6018 shares the envelope at a coarser tolerance class.
