634 miniature ball bearing include 634 bearing, 634 2RS bearings,634ZZ bearings.
Miniature bearing are simple in design, non-separable, suitable for high and even very high speeds and are robust in operation, requiring little maintenance.Deep-groove bearings have higher load ratings for their size than shallow-groove , but are also less tolerant of misalignment of the inner and outer races
Miniature bearing suitable for precision instrument, low noise electromotor, automobile and motorcycle, binding machines, plastic packaging machines, wringing machine, machine pad iron, vibration plate, screw type cold water machine, welding machine, cutting machine, steel making equipment, air purification equipment, vortex pump, beverage shop equipment, plastic wire drawing machine, soil tillage machinery, stainless steel reactor, forklift, building materials rubber cutting machine, and so on. It is the the most widely used bearing type.
