SKF 6300-2Z Metal Shielded Single Row Deep Groove Ball Bearing 10x35x11mm

The SKF 6300-2Z metal shielded deep groove ball bearing provides reliable rotational support for equipment requiring a 10mm shaft bore and a 35mm outside diameter. Its 63 series construction offers a larger bearing cross-section than the corresponding 6200 series, making it suitable for applications where housing space permits a more substantial bearing. The single row deep groove raceways accommodate predominantly radial loads together with axial forces in either direction, within the bearing's rated capacity. SKF specifies a basic dynamic load rating of 8.52kN and a basic static load rating of 3.4kN. These values help engineers assess operating loads and calculate bearing service life in compact machinery and power transmission equipment.

The 2Z designation identifies non-contact metal shields fitted on both sides of the bearing. Unlike rubber contact seals, these shields do not rub continuously against the inner ring, reducing seal-related friction and making the bearing particularly suitable for higher-speed applications. They help retain factory-applied grease and restrict larger contaminants, although they provide less protection against fine dust, water and washdown conditions than contact seals. SKF lists a 50,000rpm reference speed and a 26,000rpm limiting speed; these are catalogue values rather than guaranteed operating speeds under every load and temperature condition. The bearing features normal (CN) radial internal clearance, a sheet metal cage and an approximate mass of 55g. When replacing an existing bearing, confirm the 2Z shield configuration and clearance specification, as sealed or C3 variants may behave differently in service.
