6914, 6914Z, 6914ZZ, 6914RS, 6914-2RS Deep Groove Ball Bearings 70x100x16mm – Heavy-Duty Precision Bearings for High-Speed Industrial & Mechanical Systems
High-performance 6914 series deep groove ball bearings in size 70mm (ID) × 100mm (OD) × 16mm (W), engineered for heavy-duty industrial and mechanical systems that demand reliable, smooth, and high-speed rotation under substantial radial and moderate axial loads. Ideal for demanding applications where strength, durability, and extended service life are essential.
Available in multiple sealing configurations to suit diverse operating environments:
-
6914: Open type – best for clean or controlled settings with custom lubrication
-
6914Z / 6914ZZ (6914-2Z): Single or double metal shields – protect against dust while retaining factory grease
-
6914RS / 6914-2RS: 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, mining and construction machinery, pumps, compressors, conveyors, textile equipment, and heavy-duty drivetrain components.
Most sealed variants are pre-lubricated with long-life, low-torque grease for maintenance-free operation. The 6914 series offers an optimal balance of high load capacity, rotational accuracy, and rugged design, making it a trusted solution for both OEM integration and industrial maintenance.
