The Quick Details

16011, 16011Z, 16011ZZ, 16011RS, 16011-2RS Deep Groove Ball Bearings 55x90x11mm – Thin-Section Precision Bearings for Industrial Motors, Large Fans, Pumps & Heavy Machinery

The 16011 series deep groove ball bearings feature thin-section dimensions of 55mm (ID) × 90mm (OD) × 11mm (W), delivering robust performance in space-constrained yet high-demand applications requiring a 55mm shaft. Ideal for large industrial motors, centrifugal fans, water and oil pumps, compressors, agricultural equipment, and heavy-duty transmission systems.

Available in multiple sealing configurations to suit your operating environment:

16011: Open type – minimal friction, ideal for clean or oil-lubricated systems
16011Z / 16011ZZ: Single or double metal shields – reduce dust ingress while retaining factory grease
16011RS / 16011-2RS: 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 extended service life. Stainless steel versions are available upon request for corrosive or hygiene-critical environments.

Commonly used in industrial AC/DC motors, blowers, gearboxes, conveyor rollers, and rotating assemblies, the 16011 series combines a strong 55mm bore with a slim 11mm cross-section—making it perfect for moderate to heavy-load applications where radial space is limited but reliability and load capacity are essential.
