Product Overview
The MR105ZZ bearing is a metric-size miniature deep groove ball bearing designed for high precision and reliable performance in compact spaces. With a 5 mm bore diameter and 10 mm outside diameter, this bearing is widely used in applications where size constraints, durability, and efficiency are critical.
Manufactured from high-quality chrome steel (GCr15 / AISI 52100 equivalent), the MR105ZZ offers excellent load capacity and wear resistance. The ZZ metal shields on both sides provide protection against dust and contaminants while allowing low-friction operation, making it suitable for both high-speed and continuous-use environments.
