Bearing Parts Single Row Deep Groove Ball Bearing Inner Rings for 6310 Ball Bearings
Product:BIR4011 Double row ball bearing ring
Inner rings can be integrated with shell-type or various machined needle roller bearings to provide good roller support without worrying about premature shaft wear. We heat-treat and grind our inner rings to tight tolerances to create hard, tough raceways for applications where it is impossible to make shaft surfaces to a specific hardness or roughness attribute. They’re an economical alternative to bushings because they don’t require any additional machining. Wide inner rings are also available to accommodate shafts that move axially or seals that are adjacent to bearings. Inner rings come in a broad range of shaft diameters, and assembly elements include small chamfers or gentle taper relief options.
And Deep groove ball bearings mainly bear radial load as well as take moderate axial load. With less coefficient of friction, high limiting speed, large size range and variations of structure, deep groove ball bearings are suitable for precision instruments, low noise motors, automobiles, motorcycles, air-conditioners, washers, cleaners and other common machineries as a widely used type of bearings in machinery industry.
