W 61911-2Z Deep groove ball bearing, originally listed as radial ball bearing, is a widely used rolling bearing.It is characterized by low friction resistance and high rotation speed, and can be used on parts bearing radial load or combined radial and axial load simultaneously, and also on parts bearing axial load, such as small power motors, automobile and tractor gearboxes, machine tool gearboxes, general machines, tools, etc.Deep groove ball bearings can be used for gearboxes, instruments and meters, motors, household appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, engineering machinery, roller skates, yo-yo balls, etc.
