💡 How do you choose the right angular contact bearing for heavy duty spindle applications?
You actually need a sealed ceramic unit that holds your spindle square while sweating heat during rapid direction changes.
- Search for a solid Si3N4 core that throws off friction and keeps expansion low when your router runs warm.
- Look for a handy twin pack layout that shares the load evenly and damps shaking on chunky stock.
- Buy a drop-in ring style that skips fancy alignment tools and gets your lathe running smooth again tomorrow.
