💡 When should you use a thrust bearing instead of a radial bearing?
Thrust bearings are specifically designed to handle loads parallel to the shaft (axial), not radial loads. They’re the go-to choice for applications like turntables, vertical drives, and screw jacks where axial stability is critical.

For high axial loads with smooth rotation, this bearing gets it done - add it to your build and keep things turning with confidence!
