6809, 6809Z, 6809ZZ, 6809RS, 6809-2RS Ball Bearings 45x58x7mm – Compact Deep Groove Ball Bearings for High-Speed Industrial & Heavy-Duty Mechanical Systems

6809, 6809Z, 6809ZZ, 6809RS, 6809-2RS Ball Bearings 45x58x7mm – Compact Deep Groove Ball Bearings for High-Speed Industrial & Heavy-Duty Mechanical Systems

High-performance 6809 series deep groove ball bearings in size 45mm (ID) × 58mm (OD) × 7mm (W), engineered for industrial and heavy-duty mechanical systems that require reliable, smooth, and quiet operation under moderate to heavy radial loads. Available in multiple sealing configurations to suit diverse operating environments:

• 6809: Open type – ideal for clean or controlled settings with custom lubrication
• 6809Z / 6809ZZ (6809-2Z): Single or double metal shields – protect against dust while retaining factory grease
• 6809RS / 6809-2RS: Single or double rubber seals – provide excellent resistance to moisture, dirt, and contaminants

Manufactured from premium chrome steel (GCr15) with precision-ground raceways, these bearings ensure low friction, minimal noise, and stable high-speed performance. Widely used in electric motors, gearboxes, agricultural machinery, construction equipment, pumps, compressors, conveyor systems, and industrial automation.

Most sealed models are pre-lubricated with high-quality grease for maintenance-free operation. The 6809 series supports both radial and limited axial loads, making it a robust solution for demanding mechanical applications requiring durability and extended service life.
