6808, 6808Z, 6808ZZ, 6808RS, 6808-2RS Ball Bearings 40x52x7mm – Compact Deep Groove Ball Bearings for High-Speed Industrial & Mechanical Applications

Reliable and robust 6808 series deep groove ball bearings in size 40mm (ID) × 52mm (OD) × 7mm (W), engineered for industrial machinery and mechanical systems that demand smooth, quiet, and durable performance under moderate radial loads. Available in multiple sealing options to suit diverse operating conditions:

• 6808: Open type – ideal for clean environments or applications requiring custom lubrication
• 6808Z / 6808ZZ (6808-2Z): Single or double metal shields – protect against dust while retaining factory grease
• 6808RS / 6808-2RS: Single or double rubber seals – offer superior resistance to moisture, dirt, and contaminants

Manufactured from high-quality chrome steel (GCr15) with precision-ground raceways, these bearings deliver low friction, minimal noise, and consistent high-speed performance. Commonly used in electric motors, gearboxes, agricultural machinery, conveyor systems, pumps, compressors, HVAC equipment, and light-to-medium industrial automation.

Most sealed variants are pre-lubricated with high-performance grease for maintenance-free operation. The 6808 series supports both radial and limited axial loads, making it a versatile choice for demanding mechanical designs requiring long service life and reliability.
