💡 What is a common use case for a small inch-size radial ball bearing?

These bearings are handy for supporting rotating shafts in tight spaces where simple radial loads are expected. They pair with standard shafts and fit drill presses, small lathes, conveyors, and light industrial tooling. - Fits compact equipment with limited mounting room - Supports steady radial loads on rotating shafts - Works with standard shaft tolerances for easy maintenance
