The Quick Details

R1810, R1810Z, R1810ZZ, R1810RS, R1810-2RS Inch Flanged Deep Groove Ball Bearings 5/16"x1/2"x5/32" (7.938x12.7x3.967mm) – Sealed Flange Bearings for Small Motors, Fans, Office Equipment & Precision Machinery

The R1810 series inch deep groove ball bearings feature a built-in flange on the outer ring for axial location, eliminating the need for retaining rings or complex housing designs. Standard dimensions: 5/16"x1/2"x5/32" (7.938x12.7x3.967mm).

Ideal for space-constrained applications requiring simple mounting and high rotational accuracy—commonly used in small electric motors, cooling fans, printers, scanners, HVAC blowers, and precision instruments.

Available in multiple sealing options:

R1810: Open type – minimal friction, for clean or oil-lubricated systems
R1810Z / R1810ZZ: Single/double metal shields – reduce dust ingress
R1810RS / R1810-2RS: Single/double rubber seals – excellent protection against moisture and contaminants

Made from high-grade chrome steel (SAE 52100) with precision grinding for quiet, smooth operation. Stainless steel (440C) versions available for corrosive environments.
