Precision Miniature MR105ZZ Deep Groove Ball Bearing

Ultra-Smooth Performance: Chrome steel construction with hardened raceways ensures low friction rotation at speeds up to 30,000 RPM. Polyamide cage maintains precise ball alignment for vibration-free operation.

Micro-Sized Versatility: Compact 5x10x4mm design fits tight spaces in drones, RC models, medical devices, and optical equipment. Shielded (ZZ) variant protects against dust while allowing grease retention.

High-Speed Endurance: Grade-10 precision balls polished to 0.25μm surface finish deliver quiet rotation. Ideal for miniature motors, dental tools, and precision instruments requiring 0.002mm radial runout accuracy.

Industrial-Grade Reliability: Heat-stabilized rings resist deformation under load. Pre-lubricated with high-temperature grease (-30°C to +120°C) for maintenance-free operation in robotics and automation systems.

Bulk Purchase Advantage: Direct factory pricing with MOQ discounts. ISO 9001 certified production ensures batch-to-batch consistency for OEM applications. Ships in anti-corrosion vacuum packaging.
