The Quick Details

6910, 6910Z, 6910ZZ, 6910RS, 6910-2RS Deep Groove Ball Bearings 50x72x12mm – Heavy-Duty Precision Bearings for High-Speed Industrial & Mechanical Systems

High-performance 6910 series deep groove ball bearings in size 50mm (ID) × 72mm (OD) × 12mm (W), designed for heavy-duty industrial and mechanical systems that require reliable, smooth, and high-speed rotation under substantial radial and moderate axial loads. Ideal for demanding applications where strength, durability, and long service life are essential.

Available in multiple sealing configurations to suit diverse operating environments:

6910: Open type – best for clean or controlled settings with custom lubrication
6910Z / 6910ZZ (6910-2Z): Single or double metal shields – protect against dust while retaining factory grease
6910RS / 6910-2RS: 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 vibration, and stable performance at elevated speeds. Commonly used in large electric motors, industrial gearboxes, construction and mining machinery, pumps, compressors, conveyors, textile equipment, and heavy automotive components.

Most sealed variants are pre-lubricated with long-life, low-torque grease for maintenance-free operation. The 6910 series offers an optimal balance of high load capacity, rotational accuracy, and robust design, making it a trusted solution for both OEM integration and industrial maintenance.
