💡 What is a self aligning ball bearing used for in heavy machinery?
Self aligning bearings are designed to tolerate shaft misalignment while supporting radial loads in tough equipment.
- Accommodate angular misalignment in conveyors, gearboxes, and fans
- Reduce stress on shafts and housings under high dynamic loads
- Ideal when precise alignment during install is hard to achieve
