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. Can be used to build the track system or replace the wheel, widely used in door and window to track, or drive mechanical equipment.
Selection 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.
