6901, 6901Z, 6901ZZ, 6901RS, 6901-2RS Miniature Ball Bearings 12x24x6mm – Compact Deep Groove Bearings for High-Speed Precision & Light-Duty Mechanical Systems

6901, 6901Z, 6901ZZ, 6901RS, 6901-2RS Miniature Ball Bearings 12x24x6mm – Compact Deep Groove Bearings for High-Speed Precision & Light-Duty Mechanical Systems

High-performance 6901 series miniature deep groove ball bearings in size 12mm (ID) × 24mm (OD) × 6mm (W), engineered for compact mechanisms and light-duty mechanical systems that require smooth, quiet, and high-speed rotation under radial and limited axial loads. Available in multiple sealing options to suit diverse operating environments:

• 6901: Open type – ideal for clean or controlled settings with custom lubrication
• 6901Z / 6901ZZ (6901-2Z): Single or double metal shields – protect against dust while retaining factory grease
• 6901RS / 6901-2RS: Single or double rubber seals – offer superior 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 vibration, and reliable performance at elevated speeds. Commonly used in small electric motors, power tools, drones, RC vehicles, robotics, office equipment, 3D printers, medical devices, and household appliances.

Most sealed variants are pre-lubricated with low-torque, long-life grease for maintenance-free operation. The 6901 series delivers an excellent balance of compact size, load capacity, and rotational efficiency, making it ideal for space-constrained applications where durability and smooth motion are essential.
