High-performance 698 series miniature deep groove ball bearings in size 8mm (ID) × 19mm (OD) × 6mm (W), designed for compact mechanisms and micro-mechanical systems requiring smooth, quiet, and high-speed rotation under light to moderate radial loads. Available in multiple sealing configurations to suit diverse operating environments:
- 698: Open type – ideal for clean or controlled settings with custom lubrication
- 698Z / 698ZZ (698-2Z): Single or double metal shields – protect against dust while retaining factory grease
- 698RS / 698-2RS: Single or double rubber seals – provide excellent resistance to moisture and fine contaminants
Manufactured from premium chrome steel (GCr15) — with stainless steel available on request — these bearings feature precision-ground raceways for low friction, minimal noise, and reliable operation at high RPMs. Widely used in small electric motors, power tools, drones, RC vehicles, robotics, medical devices, 3D printers, scanners, smart locks, and household appliances.
Most sealed models come pre-lubricated with low-torque, long-life grease for maintenance-free performance. The 698 series supports both radial and limited axial loads, making it a versatile solution for space-constrained, high-efficiency designs where durability and smooth motion are essential.
