KT589 -Roller - K5x8x9

KT589 needle roller cage bearing
✔️ 5mm x 8mm x 9mm compact high-load miniature design

This single KT589 needle roller bearing cage is built for tight spaces where high radial load capacity and smooth motion are essential. Its open cage design ensures efficient lubrication and low friction, making it perfect for gearboxes, transmissions, and precision miniature mechanisms.

✅ Size: 5mm inner diameter x 8mm outer diameter x 9mm width
✅ Type: needle roller cage bearing (open design)
✅ Material: hardened bearing steel
✅ Application: compact, high-load radial systems
✅ Pack size: one bearing

💡 Why choose a needle roller cage bearing for small assemblies?
It handles heavy radial loads with minimal space and friction.
- Maximizes strength in compact designs
- Improves rotation efficiency and lubrication flow
- Ideal for high-speed, space-limited mechanisms
