6814, 6814Z, 6814ZZ, 6814RS, 6814-2RS Ball Bearings 70x90x10mm – Heavy-Duty Deep Groove Ball Bearings for High-Speed Industrial & Mechanical Systems

6814, 6814Z, 6814ZZ, 6814RS, 6814-2RS Ball Bearings 70x90x10mm – Heavy-Duty Deep Groove Ball Bearings for High-Speed Industrial & Mechanical Systems

High-performance 6814 series deep groove ball bearings in size 70mm (ID) × 90mm (OD) × 10mm (W), designed for heavy-duty industrial and mechanical applications requiring reliable operation under moderate to high radial loads. Available in multiple sealing options to suit diverse operating environments:

• 6814: Open type – ideal for clean or controlled settings with custom lubrication
• 6814Z / 6814ZZ (6814-2Z): Single or double metal shields – protect against dust while retaining factory grease
• 6814RS / 6814-2RS: Single or double rubber seals – offer superior resistance to moisture, dirt, and contaminants

Manufactured from premium chrome steel (GCr15) with precision-ground raceways, these bearings deliver low friction, minimal noise, and stable high-speed performance. Commonly used in large electric motors, industrial gearboxes, construction and mining equipment, pumps, compressors, conveyor systems, and power transmission units.

Most sealed variants are pre-lubricated with high-quality grease for maintenance-free operation. The 6814 series supports both radial and limited axial loads, making it a robust solution for demanding mechanical systems that require durability and long service life.
