💡 What is a common use case for a pillow block bearing in industrial machinery?

Pillow block bearings are handy for supporting rotating shafts in belts, conveyors, and gear drives across a range of equipment.

- Keeps shafts aligned under load to prevent wobble and wear
- Reduces friction and heat in moving parts
- Eases mounting, lubrication, and maintenance in harsh settings
