6900, 6900Z, 6900ZZ, 6900RS, 6900-2RS Miniature Ball Bearings 10x22x6mm – Compact Deep Groove Bearings for High-Speed Precision & Light-Duty Mechanical Applications

6900, 6900Z, 6900ZZ, 6900RS, 6900-2RS Miniature Ball Bearings 10x22x6mm – Compact Deep Groove Bearings for High-Speed Precision & Light-Duty Mechanical Applications

High-precision 6900 series miniature deep groove ball bearings in size 10mm (ID) × 22mm (OD) × 6mm (W), designed for compact devices and light-duty mechanical systems requiring smooth, quiet, and high-speed rotation under radial and limited axial loads. Available in multiple sealing configurations to suit various operating environments:

• 6900: Open type – ideal for clean or controlled settings with custom lubrication
• 6900Z / 6900ZZ (6900-2Z): Single or double metal shields – protect against dust while retaining factory grease
• 6900RS / 6900-2RS: 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 performance at high RPMs. Widely used in small electric motors, power tools, drones, RC models, robotics, office equipment, 3D printers, medical instruments, and household appliances.

Most sealed variants are pre-lubricated with low-torque, long-life grease for maintenance-free operation. The 6900 series offers a balanced combination of compact size, load capacity, and rotational efficiency, making it ideal for space-constrained applications where reliability matters.
