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. Selection Guide: Shields (Designation Suffix Z/ZZ) - High speed. Protect from dirt and debris. Sealed (Designation SuffixRS/2RS) - Made of sheet steel reinforced NBR (oil- and liquid-resistant). Lower limit speed than Shield Bearings. 1, Closed with metal shields to protect the bearing from dust or any possible contamination. 2, Widely used in: Roller skates, Skateboarding, Twisting cars, Running shoes, In-line wheels, Double row wheels, MTB, SUV and other Extreme sports equipment. 3, Fit for skateboards, inline skates, roller skates, scooters, and other skating applications, also available for 3D printer wheel bearings, CNC, etc. 4, Also used in industrial engineering, such as Machinery, Power Transmission, Instrumentation, Household appliances, Internal combustion engines, Transport vehicles, Agricultural machinery, Construction machinery.
