Precision MR525 Deep Groove Ball Bearing - Ultra-Smooth Performance for Miniature Applications

High-precision chrome steel construction ensures exceptional durability and wear resistance for long-lasting operation.

Micro-sized dimensions (2.5x5x1mm) engineered for compact mechanisms with tight space constraints like drone motors and watch movements.

Mirror-polished raceways and Grade 10 bearing balls minimize friction, enabling silent rotation at speeds up to 30,000 RPM.

Ideal for high-speed miniature applications: RC models, medical devices, precision instruments, and miniature robotics.

Industrial-grade lubrication pre-applied for maintenance-free performance in both dry and lubricated environments.

Direct manufacturer pricing with bulk discounts available - trusted by OEMs worldwide for consistent quality.
