Description: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.Chromium Steel (GCr15) made with heat treating, provides high and uniform hardness, good wear resistance, and high contact fatigue performance.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.
