6805, 6805Z, 6805ZZ, 6805RS, 6805-2RS Ball Bearings 25x37x7mm – Compact Deep Groove Ball Bearings for High-Speed & Precision Mechanical Systems

Reliable and compact 6805 series deep groove ball bearings in size 25mm (ID) × 37mm (OD) × 7mm (W), engineered for precision mechanical systems that require smooth, quiet, and durable rotation under light to moderate loads. Available in multiple sealing configurations to suit diverse operating environments:

• 6805: Open type – ideal for clean or controlled environments with custom lubrication
• 6805Z / 6805ZZ (6805-2Z): Single or double metal shields – protect against dust while retaining factory grease
• 6805RS / 6805-2RS: Single or double rubber seals – provide excellent resistance to moisture, dirt, and contaminants

Manufactured from high-grade chrome steel (GCr15) with precision-ground raceways, these bearings ensure low friction, minimal noise, and consistent performance at high speeds. Commonly used in small electric motors, power tools, dental equipment, robotics joints, conveyors, agricultural machinery, and light industrial automation.

Most sealed models are pre-lubricated with high-performance grease for maintenance-free operation. The 6805 series supports both radial and limited axial loads, making it suitable for a wide range of compact mechanical applications requiring reliability and long service life.
