Description:Single-row, pre-lubricated, normal accuracy.They are used to accommodate radial and axial loads in both directions(Mainly bear radial load, but also can bear a certain amount of axial load).It is constructed using chrome steel material, and its sealing type features a metal cover. With high-speed capabilities, low friction, and minimal noise levels, this bearing ensures optimal performance.This type of bearing is used in industries such as precision instruments, low-noise motors and general machinery, and is the most widely used type of bearing in the machinery industry.Selecting Guide:Open Type (No Designation Suffix) - Suitable for high-speed and even very high-speed operation.Shielded (Designation Suffix Z/ZZ) - High speed. Protect from dirt and debris.Sealed (Designation Suffix RS/2RS) - Made of sheet steel reinforced nitrile butadiene rubber (oil- and liquid-resistant). Lower limit speed than metal shield bearings.Specification:Model: 6004ZZSeal Type: Double ShieldedInner Race/Outer Race Material: Chromium Steel (GCr15)Cage Material: Stamping SteelInner Diameter: 20mmOuter Diameter: 42mmThickness: 12mmDynamic Load Rating (Cr): 9380NStatic Load Rating (Cor): 5020NAccuracy Class: ABEC3Noise Level: Z3Package Contents:2pcs x Deep Groove Ball Bearing
