Angular Contact Bearing 7309-BL1G

Angular Contact Ball Bearings 7300 Series
The angular contact light 7300 Series is dimensionally interchangeable with the radial 6300 series.
A single bearing is recommended for applications in which the trust load is in one direction or, in case of combined loads, the thrust load is high in relation to the radial load. A duplex pair is recommended for applications where trust is present in both directions or where axial displacement of the shaft must be restricted. For exceptionally high thrust loads in one direction, tandem pair can be utilized opposed by a third bearing.
Angular bearings are usually mounted in a group of two or more opposed preloaded units with rigid or elastic spacers. Typically, the inner and outer raceways and balls are made of chrome steel. Where operating conditions are severe, bearings may have ceramic balls creating a hybrid bearing. Due to their internal design, angular contact ball bearings can withstand high radial-axial loads and reach high speeds. They are asymmetrical for manufacturing reasons and can withstand unidirectional axial loads only.
