681XZZ Deep Groove Ball Bearings, ID 1.5mm x OD 4mm x Width 2mm Miniature Bearings, Double Metal Shielded Ball Bearing Chrome Steel Z2 Lever 20pcs

Specification：Model: 681XZZSeal Type: Double ShieldedInner Race/Outer Race Material: Chrome Steel (GCr15)Cage Material: Stamping SteelInner Diameter (d): 1.5mmOuter Diameter (D): 4mmThickness (B): 2mmAccuracy Class: P0 (ABEC-1)Noise Level: Z2Number of Pack: 20Feature:Single-row, pre-lubricated, normal accuracy.Deep Groove Ball Bearings are one of the most widely used rolling bearings. They are used to accommodate radial and axial loads in both directions. With small friction and high-limit speed, Ball Bearings are cost-effective and require little maintenance.These cost-effective bearings are widely used in areas with low requirements for Mohs hardness. Suitable for all kinds of industrial equipment, micro motor, small rotary motor, office equipment and so on.Selecting Guide:Shields (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 Shield Bearings.
