6906, 6906Z, 6906ZZ, 6906RS, 6906-2RS Deep Groove Ball Bearings 30x47x9mm – Precision Bearings for High-Speed & Medium-Duty Industrial Machinery

6906, 6906Z, 6906ZZ, 6906RS, 6906-2RS Deep Groove Ball Bearings 30x47x9mm – Precision Bearings for High-Speed & Medium-Duty Industrial Machinery

High-performance 6906 series deep groove ball bearings in size 30mm (ID) × 47mm (OD) × 9mm (W), designed for medium-duty industrial machinery requiring reliable, smooth, and high-speed rotation under radial and moderate axial loads. Ideal for applications where compact design meets robust performance.

Available in multiple sealing configurations to suit diverse operating environments:

• 6906: Open type – best for clean or controlled settings with custom lubrication
• 6906Z / 6906ZZ (6906-2Z): Single or double metal shields – protect against dust while retaining factory grease
• 6906RS / 6906-2RS: Single or double rubber seals – provide excellent resistance to moisture, dirt, and contaminants

Manufactured from premium chrome steel (GCr15) — with stainless steel available on request — these bearings feature precision-ground raceways for low friction, minimal noise, and stable operation at high RPMs. Commonly used in electric motors, gearboxes, agricultural equipment, pumps, compressors, conveyors, textile machinery, HVAC systems, and light automotive components.

Most sealed variants are pre-lubricated with long-life, low-torque grease for maintenance-free performance. The 6906 series offers an optimal balance of load capacity, rotational accuracy, and durability in a space-efficient design—making it a trusted solution for both OEM integration and industrial maintenance.
