635 miniature ball bearing


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, Laminated glass production line, hot melt machine, sewing equipment before, chuck, machinery field, microwave drying equipment, shear pin machine, three ring reducer, lithographic printing machine, machine, welding machine, machine repair equipment, shock absorber, industrial furnace, lathe, mining measuring instruments, coating production line, compaction machinery,etc. It is the the most widely used bearing type.
