10Pcs MF115-2RS Flanged Ball Bearing 5X11X4Mm Chrome Steel Rubber Seals (Abec 3)

Description Double-sided metal shielded bearings offer a physical barrier against larger particles and moderate amounts of dirt or dust. They are suitable for applications where moderate protection is required but not necessarily in extremely harsh environments. ABEC 3 precision bearing has lower manufacturing tolerances compared to lower-rated bearings, resulting in smoother rotation and less friction. Chrome steel material: Deep groove ball bearings are made of quality chrome steel with excellent strength, hardness, wear resistance and corrosion resistance. It can withstand significant radial and axial loads, providing reliable support in a variety of applications. Wide Application: Widely used in various high-speed motors, gearboxes, fans, mixers, juicers, treadmills, massagers, manipulators, RC cars, office equipment, machine tools, etc. 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.
