💡 What is a deep groove ball bearing used for in industrial machinery?

A handy, go‑to choice for smooth rotation and low friction across many machines.

- High speed operation in motors and conveyors (typical bore sizes around 45 mm)
- Handy radial load support with minimal friction in gearboxes
- Easy replacement in standard housings and assemblies (45 mm bore)
