6205

6205 is a standard designation for a metric deep groove ball bearing in the 6200 series. It features a bore diameter of 25 mm, an outer diameter of 52 mm, and a width of 15 mm. As a radial bearing with good load-carrying capacity and speed, it is commonly used in general machinery, household appliances, and automotive components. The 6205 bearing is available in several common variants, including 6205-2RS or 6205RS (dual rubber seals for dust and moisture protection) and 6205-Z or 6205ZZ (metal shields for reduced contamination). The suffix indicates the type of shielding or sealing and affects grease retention and protection level, while maintaining interchangeable inner and outer dimensions.

In operation, 6205 bearings are designed to support primarily radial loads with some allowance for axial loads in either direction. They are valued for their versatility, relatively simple maintenance, and wide availability from major manufacturers such as SKF, NSK, Timken, and others. Tolerances and performance characteristics depend on the specific grade and seal configuration, and users typically select a variant with appropriate lubrication and seals for the operating environment.

Applications for 6205 bearings span electric motors, gearboxes, conveyors, pumps, and various power tools. They are chosen for moderate to high-speed service and where a compact, robust, and readily replaceable bearing is required. For precise load ratings, speed limits, and installation data, the corresponding manufacturer’s datasheet should be consulted.
