description
- Extra small ball bearings can sustain radial thrust and combined loads proportionate to the capacities of the small shafts for which they are designed. They are especially suitable for use in fractional horsepower motors, domestic appliances, precision instruments, tape recorders and similar devices. These bearings are electric motor quality for applications where extra quietness is a requirement.
applications
- General industrial
- Automotive
- Agricultural
- Chemical
- Utilities
features
- Versatile and provide an easy interchange for operational efficiency
- Well balanced, all purpose bearing with deep races and uninterrupted shoulders for higher load capability
- Help electric motor applications run quieter
