SKF 4311ATN9 Double Row Deep Groove Ball Bearing 55x120x43mm

SKF Double Row Deep Groove Ball Bearings: Similar in design to single row deep groove ball bearings, they have two parallel deep grooves and high conformity between the balls and the raceways. They are able to carry axial loads in both directions in addition to radial loads. These are particularly suited to applications where a single row ball bearing's load bearing capacity would be insufficient. Made with the same bore and outside diameters as the single row series they are a little bit wider but offer far greater load bearing ability.
Benefits: Higher axial and radial load than single row, same bore and diameter as single row equivalent size.
