Miniature Bearing
MR104ZZ Miniature Bearing Product Overview
Dimensions
Inner Diameter (ID): 4 mm
Outer Diameter (OD): 10 mm
Width: 4 mm
Design & Structure
Deep Groove Ball Bearing Design: Features inner and outer rings with steel balls positioned between them, enabling smooth radial and axial load support.
Double Metal Shields: Integrated metal shields on both sides protect internal components from contaminants (e.g., dust, debris) while retaining lubrication, enhancing durability.
Material & Construction
High-Grade Chrome Steel: Inner/outer rings and steel balls are manufactured from premium chrome steel (GCr15/SAE 52100), offering exceptional wear resistance, hardness, and corrosion resistance.
Precision Engineering: Ensures stable operation under high-speed rotation and varying load conditions.
Performance Advantages
High-Speed Capability: Optimized for high-speed applications with low friction and minimal heat generation. Its axial rigidity minimizes energy loss during rapid rotation.
Contaminant Resistance: Metal shields provide robust protection against dust and moisture ingress, prolonging service life in harsh environments.
Applications
Ideal for compact, high-efficiency systems such as:
Micro motors and drones
Precision instruments and electronic devices
Model kits,Nezha toys, and small machinery
Rotary components requiring friction reduction and smooth motion.
Summary
The MR104ZZ is a versatile, miniature deep groove ball bearing designed to deliver reliable performance in space-constrained, high-speed applications. Its chrome steel construction, dual metal shields, and precision engineering ensure durability, contaminant resistance, and consistent operation across industries like robotics, electronics, and micro-mechanics.
