6806, 6806Z, 6806ZZ, 6806RS, 6806-2RS Ball Bearings 30x42x7mm – Compact Deep Groove Ball Bearings for High-Speed & Precision Industrial Applications

Robust and precision-engineered 6806 series deep groove ball bearings in size 30mm (ID) × 42mm (OD) × 7mm (W), designed for industrial and mechanical systems requiring reliable, quiet, and high-speed rotation under light to moderate radial loads. Available in multiple sealing options to suit diverse operating conditions:

• 6806: Open type – ideal for clean environments or custom lubrication setups
• 6806Z / 6806ZZ (6806-2Z): Single or double metal shields – protect against dust while retaining factory grease
• 6806RS / 6806-2RS: 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 performance at elevated speeds. Commonly used in electric motors, gearboxes, agricultural machinery, food processing equipment, conveyors, HVAC blowers, and light industrial automation.

Most sealed variants are pre-lubricated with high-performance grease for maintenance-free operation. The 6806 series supports both radial and limited axial loads, making it a versatile choice for compact mechanical designs demanding durability and long service life.
