The Quick Details

16004, 16004Z, 16004ZZ, 16004RS, 16004-2RS Deep Groove Ball Bearings 20x42x8mm – Thin-Section Precision Bearings for Small Motors, Power Tools, Appliances & Office Equipment

The 16004 series deep groove ball bearings feature thin-section dimensions of 20mm (ID) × 42mm (OD) × 8mm (W), offering reliable performance in compact designs that require a 20mm shaft. Ideal for small electric motors, power tools, household appliances (e.g., washing machines, fans, food processors), office equipment (printers, copiers), and light industrial machinery.

Available in multiple sealing configurations to match your operating environment:

16004: Open type – minimal friction, perfect for clean or oil-lubricated systems
16004Z / 16004ZZ: Single or double metal shields – reduce dust ingress while retaining factory grease
16004RS / 16004-2RS: Single or double rubber seals – provide excellent protection against moisture, dust, and fine contaminants

Manufactured from high-quality chrome steel (GCr15) with precision grinding, these bearings ensure smooth rotation, low noise, and long service life. Stainless steel versions are available upon request for corrosive or hygiene-sensitive applications.

Commonly used in AC/DC motors, gearboxes, conveyor rollers, and rotating assemblies, the 16004 series combines a practical 20mm bore with a slim 8mm cross-section—making it ideal for moderate-load applications where radial space is limited but reliability is critical.
