6705, 6705Z, 6705ZZ, 6705RS, 6705-2RS Ball Bearings 25x32x4mm – Miniature Deep Groove Ball Bearings for High-Speed & Precision Mechanical Applications

High-precision 6705 series miniature ball bearings in compact size 25mm (ID) × 32mm (OD) × 4mm (W), designed for space-efficient, high-speed, and low-noise mechanical systems. Available in multiple configurations to suit diverse operating conditions:

• 6705: Open type – ideal for applications requiring re-lubrication or custom sealing
• 6705Z / 6705ZZ (6705-2Z): Single or double metal shields – provide effective protection against dust and help retain lubricant
• 6705RS / 6705-2RS: Single or double rubber seals – offer superior resistance to moisture, dirt, and contaminants

Made from high-quality chrome steel (GCr15), these bearings feature precision-ground raceways for smooth, quiet rotation and long service life under light to moderate radial loads. Widely used in small electric motors, power tools, drones, RC models, 3D printers, robotics, medical devices, office equipment, and precision automation systems.

Most sealed versions are pre-lubricated with high-performance grease for maintenance-free operation. The 6705 series supports both radial and limited axial loads, making it ideal for compact, high-speed applications where reliability and efficiency are critical.
