6204

6204 is a standard designation for a single-row deep groove ball bearing in the 6200 series. It designates a bearing with a bore of 20 mm, an outer diameter of 47 mm, and a width of 14 mm, making it a compact, versatile component used in a wide range of machinery. The 6200 series is known for its simple construction, low friction, and ability to accommodate both radial loads and light axial loads in either direction.

Variants of the 6204 bearing include configurations with seals or shields. Common examples are the 6204-2RS, which has two rubber seals for dust and moisture exclusion, and the 6204-Z or 6204-ZZ, which use metal shields. Variants with different cage materials or heat treatments may also be offered by manufacturers. Bearings are typically produced in chrome steel (such as SAE 52100) or stainless steel, with tolerances aligned to industry standards.

Applications of the 6204 bearing span automotive, industrial, and consumer domains. They are frequently used in electric motors, gearboxes, appliances, power tools, and various machinery where a compact, reliable radial bearing with moderate load capacity is required. Availability in sealed or shielded variants makes them suitable for environments with contamination, moisture, or limited lubrication.

Manufacturing and standards: the 6204 designation follows widely used bearing numbering conventions developed by major manufacturers. While exact tolerances and materials vary by producer, the general specification remains recognizable across brands, contributing to interchangeability in maintenance and repair contexts.
