💡 What is a double-row ball bearing typically used for?

This type is handy in heavy machinery where shafts face big radial loads and need solid alignment.

- Handles higher radial loads in compact spaces.
- Great for conveyors, gearboxes, and rotating equipment requiring precise shaft alignment.
- Shielded on both sides helps keep contaminants out and grease in.
