Hey mechanics and DIYers, these uxcell thrust ball bearings are seriously solid! Each one measures 17mm inner diameter, 30mm outer diameter, and 9mm thick - perfect dimensions for plenty of applications. Made from chrome steel (AISI 52100), they're built to handle heavy axial loads with a dynamic load rating of 10.8kN and static load of 18.2kN. The one-way design means they only take pressure from one direction, so make sure you install them correctly. They're separable too, which makes maintenance and inspection super easy. Perfect for oven turntables, jacks, pumps, or any rotating machinery that needs to handle axial forces. The P5 tolerance means they're precision-made for smooth operation. Just remember - keep them clean and properly lubricated, and they'll last you ages. At 3 pieces per pack, you've got spares for future projects or replacements. Seriously, if you're working on anything that spins and needs to handle push forces, these bearings are absolutely essential!
