20 Packs MR52ZZ Deep Groove Ball Bearings 2x5x2.5mm Chrome Steel Miniature Bearing Double Shielded, P6 (ABEC 3)

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.

Z2 Noise Level: The Z2 noise level enables it to provide a quieter operating environment and is especially suitable for occasions with higher noise requirements.

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.
